Building the ThreadX run-time Library + +First make sure you are in the "example_build" directory. Also, make sure that +you have setup your path and other environment variables necessary for the ARM +AC5 development environment. At this point you may run the build_threadx.bat +batch file. This will build the ThreadX run-time environment in the +"example_build" directory. + +You should observe assembly and compilation of a series of ThreadX source +files. At the end of the batch file, they are all combined into the +run-time library file: tx.a. This file must be linked with your +application in order to use ThreadX. + + +2. Demonstration System + +Since there is no ARM11 FVP, there are no instructions here for running +the demonstration; users are expected to run the demonstration on their +platform of choice. + +Building the demonstration is easy; simply execute the build_threadx_sample.bat +batch file while inside the "example_build" directory. + +You should observe the compilation of sample_threadx.c (which is the demonstration +application) and linking with tx.a. The resulting file sample_threadx.axf +is a binary file that can be downloaded and executed on the user's platform of choice. + + +3. System Initialization + +The entry point in ThreadX for the Cortex-A5 using AC5 tools is at label +__main. This is defined within the AC5 compiler's startup code. In addition, +this is where all static and global pre-set C variable initialization processing +takes place. + +The ThreadX tx_initialize_low_level.s file is responsible for setting up +various system data structures, the vector area, and a periodic timer interrupt +source. By default, the vector area is defined to be located in the Init area, +which is defined at the top of tx_initialize_low_level.s. This area is typically +located at 0. In situations where this is impossible, the vectors at the beginning +of the Init area should be copied to address 0. + +This is also where initialization of a periodic timer interrupt source +should take place. + +In addition, _tx_initialize_low_level determines the first available +address for use by the application, which is supplied as the sole input +parameter to your application definition function, tx_application_define. + + +4.

This define + should also be used in conjunction + with the corresponding assembler + define. + -DTX_DISABLE_ERROR_CHECKING If defined before tx_api.h is included, + this define causes basic ThreadX error + checking to be disabled. Please see + Chapter 2 in the "ThreadX User Guide" + for more details. + + -DTX_MAX_PRIORITIES Defines the priority levels for ThreadX. + Legal values range from 32 through + 1024 (inclusive) and MUST be evenly divisible + by 32. Increasing the number of priority levels + supported increases the RAM usage by 128 bytes + for every group of 32 priorities. However, there + is only a negligible effect on performance.

However, using this option moves all + the timer expiration processing to the timer ISR level. + By default, this option is not defined. + + -DTX_REACTIVATE_INLINE Defined, this option performs reactivation of ThreadX + timers in-line instead of using a function call. This + improves performance but slightly increases code size. + By default, this option is not defined. + + -DTX_DISABLE_STACK_FILLING Defined, placing the 0xEF value in each byte of each + thread's stack is disabled.

This define is only pertinent if the ThreadX + library is built with TX_ENABLE_EVENT_TRACE defined. + + + +5. Register Usage and Stack Frames + +The AC5 compiler assumes that registers r0-r3 (a1-a4) and r12 (ip) are scratch +registers for each function. All other registers used by a C function must +be preserved by the function. ThreadX takes advantage of this in situations +where a context switch happens as a result of making a ThreadX service call +(which is itself a C function). In such cases, the saved context of a thread +is only the non-scratch registers. + +The following defines the saved context stack frames for context switches +that occur as a result of interrupt handling or from thread-level API calls. +All suspended threads have one of these two types of stack frames. The top +of the suspended thread's stack is pointed to by tx_thread_stack_ptr in the +associated thread control block TX_THREAD. + + + + Offset Interrupted Stack Frame Non-Interrupt Stack Frame + + 0x00 1 0 + 0x04 CPSR CPSR + 0x08 r0 (a1) r4 (v1) + 0x0C r1 (a2) r5 (v2) + 0x10 r2 (a3) r6 (v3) + 0x14 r3 (a4) r7 (v4) + 0x18 r4 (v1) r8 (v5) + 0x1C r5 (v2) r9 (v6) + 0x20 r6 (v3) r10 (v7) + 0x24 r7 (v4) r11 (fp) + 0x28 r8 (v5) r14 (lr) + 0x2C r9 (v6) + 0x30 r10 (v7) + 0x34 r11 (fp) + 0x38 r12 (ip) + 0x3C r14 (lr) + 0x40 PC + + +6. Improving Performance + +The distribution version of ThreadX is built without any compiler +optimizations. This makes it easy to debug because you can trace or set +breakpoints inside of ThreadX itself. Of course, this costs some +performance. To make it run faster, you can change the build_threadx.bat file to +remove the -g option and enable all compiler optimizations. + +In addition, you can eliminate the ThreadX basic API error checking by +compiling your application code with the symbol TX_DISABLE_ERROR_CHECKING +defined. + + +7. Interrupt Handling + +ThreadX provides complete and high-performance interrupt handling for Cortex-A5 +targets. There are a certain set of requirements that are defined in the +following sub-sections: + + +7.1 Vector Area + +The Cortex-A5 vectors start at address zero. The demonstration system startup +Init area contains the vectors and is loaded at address zero. On actual +hardware platforms, this area might have to be copied to address 0. + + +7.2 IRQ ISRs + +ThreadX fully manages standard and vectored IRQ interrupts. ThreadX also supports nested +IRQ interrupts. The following sub-sections define the IRQ capabilities. + + +7.2.1 Standard IRQ ISRs + +The standard ARM IRQ mechanism has a single interrupt vector at address 0x18. This IRQ +interrupt is managed by the __tx_irq_handler code in tx_initialize_low_level. The following +is the default IRQ handler defined in tx_initialize_low_level.s: + + EXPORT __tx_irq_handler + EXPORT __tx_irq_processing_return +__tx_irq_handler +; +; /* Jump to context save to save system context. */ + B _tx_thread_context_save ; Jump to the context save +__tx_irq_processing_return +; +; /* At this point execution is still in the IRQ mode. The CPSR, point of +; interrupt, and all C scratch registers are available for use. Note +; that IRQ interrupts are still disabled upon return from the context +; save function. */ +; +; /* Application ISR call(s) go here! */ +; +; /* Jump to context restore to restore system context. */ + B _tx_thread_context_restore + + +7.2.2 Vectored IRQ ISRs + +The vectored ARM IRQ mechanism has multiple interrupt vectors at addresses specified +by the particular implementation. The following is an example IRQ handler defined in +tx_initialize_low_level.s: + + EXPORT __tx_irq_example_handler +__tx_irq_example_handler +; +; /* Call context save to save system context. */ + + STMDB sp!, {r0-r3} ; Save some scratch registers + MRS r0, SPSR ; Pickup saved SPSR + SUB lr, lr, #4 ; Adjust point of interrupt + STMDB sp!, {r0, r10, r12, lr} ; Store other scratch registers + BL _tx_thread_vectored_context_save ; Call the vectored IRQ context save +; +; /* At this point execution is still in the IRQ mode. The CPSR, point of +; interrupt, and all C scratch registers are available for use. Note +; that IRQ interrupts are still disabled upon return from the context +; save function. */ +; +; /* Application ISR call goes here! */ +; +; /* Jump to context restore to restore system context. */ + B _tx_thread_context_restore + + +7.2.3 Nested IRQ Support + +By default, nested IRQ interrupt support is not enabled. To enable nested +IRQ support, the entire library should be built with TX_ENABLE_IRQ_NESTING +defined. With this defined, two new IRQ interrupt management services are +available, namely _tx_thread_irq_nesting_start and _tx_thread_irq_nesting_end. +These function should be called between the IRQ context save and restore +calls. + +Execution between the calls to _tx_thread_irq_nesting_start and +_tx_thread_irq_nesting_end is enabled for IRQ nesting. This is achieved +by switching from IRQ mode to SYS mode and enabling IRQ interrupts. +The SYS mode stack is used during the SYS mode operation, which was +setup in tx_initialize_low_level.s. When nested IRQ interrupts are no longer required, +calling the _tx_thread_irq_nesting_end service disables nesting by disabling +IRQ interrupts and switching back to IRQ mode in preparation for the IRQ +context restore service. + +The following is an example of enabling IRQ nested interrupts in a standard +IRQ handler: + + EXPORT __tx_irq_handler + EXPORT __tx_irq_processing_return +__tx_irq_handler +; +; /* Jump to context save to save system context. */ + B _tx_thread_context_save +__tx_irq_processing_return +; +; /* Enable nested IRQ interrupts. NOTE: Since this service returns +; with IRQ interrupts enabled, all IRQ interrupt sources must be +; cleared prior to calling this service. */ + BL _tx_thread_irq_nesting_start +; +; /* Application ISR call(s) go here! */ +; +; /* Disable nested IRQ interrupts. The mode is switched back to +; IRQ mode and IRQ interrupts are disable upon return. */ + BL _tx_thread_irq_nesting_end +; +; /* Jump to context restore to restore system context. */ + B _tx_thread_context_restore + + +7.3 FIQ Interrupts + +By default, Cortex-A5 FIQ interrupts are left alone by ThreadX. Of course, this +means that the application is fully responsible for enabling the FIQ interrupt +and saving/restoring any registers used in the FIQ ISR processing. To globally +enable FIQ interrupts, the application should enable FIQ interrupts at the +beginning of each thread or before any threads are created in tx_application_define. +In addition, the application must ensure that no ThreadX service calls are made +from default FIQ ISRs, which is located in tx_initialize_low_level.s. + + +7.3.1 Managed FIQ Interrupts + +Full ThreadX management of FIQ interrupts is provided if the ThreadX sources +are built with the TX_ENABLE_FIQ_SUPPORT defined. If the library is built +this way, the FIQ interrupt handlers are very similar to the IRQ interrupt +handlers defined previously. The following is default FIQ handler +defined in tx_initialize_low_level.s: + + + EXPORT __tx_fiq_handler + EXPORT __tx_fiq_processing_return +__tx_fiq_handler +; +; /* Jump to fiq context save to save system context. */ + B _tx_thread_fiq_context_save +__tx_fiq_processing_return: +; +; /* At this point execution is still in the FIQ mode. The CPSR, point of +; interrupt, and all C scratch registers are available for use. */ +; +; /* Application FIQ handlers can be called here! */ +; +; /* Jump to fiq context restore to restore system context. */ + B _tx_thread_fiq_context_restore + + +7.3.1.1 Nested FIQ Support + +By default, nested FIQ interrupt support is not enabled. To enable nested +FIQ support, the entire library should be built with TX_ENABLE_FIQ_NESTING +defined. With this defined, two new FIQ interrupt management services are +available, namely _tx_thread_fiq_nesting_start and _tx_thread_fiq_nesting_end. +These function should be called between the FIQ context save and restore +calls. + +Execution between the calls to _tx_thread_fiq_nesting_start and +_tx_thread_fiq_nesting_end is enabled for FIQ nesting. This is achieved +by switching from FIQ mode to SYS mode and enabling FIQ interrupts. +The SYS mode stack is used during the SYS mode operation, which was +setup in tx_initialize_low_level.s. When nested FIQ interrupts are no longer required, +calling the _tx_thread_fiq_nesting_end service disables nesting by disabling +FIQ interrupts and switching back to FIQ mode in preparation for the FIQ +context restore service. + +The following is an example of enabling FIQ nested interrupts in the +typical FIQ handler: + + + EXPORT __tx_fiq_handler + EXPORT __tx_fiq_processing_return +__tx_fiq_handler +; +; /* Jump to fiq context save to save system context. */ + B _tx_thread_fiq_context_save +__tx_fiq_processing_return +; +; /* At this point execution is still in the FIQ mode. The CPSR, point of +; interrupt, and all C scratch registers are available for use. */ +; +; /* Enable nested FIQ interrupts. NOTE: Since this service returns +; with FIQ interrupts enabled, all FIQ interrupt sources must be +; cleared prior to calling this service. */ + BL _tx_thread_fiq_nesting_start +; +; /* Application FIQ handlers can be called here! */ +; +; /* Disable nested FIQ interrupts. The mode is switched back to +; FIQ mode and FIQ interrupts are disable upon return. */ + BL _tx_thread_fiq_nesting_end +; +; /* Jump to fiq context restore to restore system context. */ + B _tx_thread_fiq_context_restore + + +8. ThreadX Timer Interrupt + +ThreadX requires a periodic interrupt source to manage all time-slicing, +thread sleeps, timeouts, and application timers. Without such a timer +interrupt source, these services are not functional. However, all other +ThreadX services are operational without a periodic timer source. + +To add the timer interrupt processing, simply make a call to +_tx_timer_interrupt in the IRQ processing. An example of this can be +found in the file tx_initialize_low_level.s in the Integrator sub-directories. + + +9. Thumb/Cortex-A5 Mixed Mode + +By default, ThreadX is setup for running in Cortex-A5 32-bit mode. This is +also true for the demonstration system. It is possible to build any +ThreadX file and/or the application in Thumb mode. If any Thumb code +is used the entire ThreadX source- both C and assembly - should be built +with the "-apcs /interwork" option. + +11. VFP Support + +By default, VFP support is disabled for each thread. If saving the context of the VFP registers +is needed, the following API call must be made from the context of the application thread - before +the VFP usage: + +void tx_thread_vfp_enable(void); + +After this API is called in the application, VFP registers will be saved/restored for this thread if it +is preempted via an interrupt. All other suspension of the this thread will not require the VFP registers +to be saved/restored. + +To disable VFP register context saving, simply call the following API: + +void tx_thread_vfp_disable(void); + + +12.

Register Usage and Stack Frames + +The GNU compiler assumes that registers r0-r3 (a1-a4) and r12 (ip) are scratch +registers for each function. All other registers used by a C function must +be preserved by the function. ThreadX takes advantage of this in situations +where a context switch happens as a result of making a ThreadX service call +(which is itself a C function). In such cases, the saved context of a thread +is only the non-scratch registers. + +The following defines the saved context stack frames for context switches +that occur as a result of interrupt handling or from thread-level API calls. +All suspended threads have one of these two types of stack frames. The top +of the suspended thread's stack is pointed to by tx_thread_stack_ptr in the +associated thread control block TX_THREAD. + + + + Offset Interrupted Stack Frame Non-Interrupt Stack Frame + + 0x00 1 0 + 0x04 CPSR CPSR + 0x08 r0 (a1) r4 (v1) + 0x0C r1 (a2) r5 (v2) + 0x10 r2 (a3) r6 (v3) + 0x14 r3 (a4) r7 (v4) + 0x18 r4 (v1) r8 (v5) + 0x1C r5 (v2) r9 (v6) + 0x20 r6 (v3) r10 (v7) + 0x24 r7 (v4) r11 (fp) + 0x28 r8 (v5) r14 (lr) + 0x2C r9 (v6) + 0x30 r10 (v7) + 0x34 r11 (fp) + 0x38 r12 (ip) + 0x3C r14 (lr) + 0x40 PC + + +6. Improving Performance + +The distribution version of ThreadX is built without any compiler +optimizations.

Interrupt Handling + +ThreadX provides complete and high-performance interrupt handling for ARM11 +targets. There are a certain set of requirements that are defined in the +following sub-sections: + + +7.1 Vector Area + +The ARM11 vectors start at address zero. The demonstration system startup +reset.S file contains the vectors and is loaded at address zero. On actual +hardware platforms, this area might have to be copied to address 0. + + +7.2 IRQ ISRs + +ThreadX fully manages standard and vectored IRQ interrupts. ThreadX also supports +nested IRQ interrupts. The following sub-sections define the IRQ capabilities. + + +7.2.1 Standard IRQ ISRs + +The standard ARM IRQ mechanism has a single interrupt vector at address 0x18. This IRQ +interrupt is managed by the __tx_irq_handler code in tx_initialize_low_level. The following +is the default IRQ handler defined in tx_initialize_low_level.S: + + .global __tx_irq_handler + .global __tx_irq_processing_return +__tx_irq_handler: +@ +@ /* Jump to context save to save system context. */ + B _tx_thread_context_save @ Jump to the context save +__tx_irq_processing_return: +@ +@ /* At this point execution is still in the IRQ mode. The CPSR, point of +@ interrupt, and all C scratch registers are available for use. Note +@ that IRQ interrupts are still disabled upon return from the context +@ save function. */ +@ +@ /* Application ISR call(s) go here! */ +@ +@ /* Jump to context restore to restore system context. */ + B _tx_thread_context_restore + + +7.2.2 Vectored IRQ ISRs + +The vectored ARM IRQ mechanism has multiple interrupt vectors at addresses specified +by the particular implementation. The following is an example IRQ handler defined in +tx_initialize_low_level.S: + + .global __tx_irq_example_handler +__tx_irq_example_handler: +@ +@ /* Call context save to save system context. */ + + STMDB sp!, {r0-r3} @ Save some scratch registers + MRS r0, SPSR @ Pickup saved SPSR + SUB lr, lr, #4 @ Adjust point of interrupt + STMDB sp!, {r0, r10, r12, lr} @ Store other scratch registers + BL _tx_thread_vectored_context_save @ Call the vectored IRQ context save +@ +@ /* At this point execution is still in the IRQ mode. The CPSR, point of +@ interrupt, and all C scratch registers are available for use. Note +@ that IRQ interrupts are still disabled upon return from the context +@ save function. */ +@ +@ /* Application ISR call goes here! */ +@ +@ /* Jump to context restore to restore system context. */ + B _tx_thread_context_restore + + +7.2.3 Nested IRQ Support + +By default, nested IRQ interrupt support is not enabled. To enable nested +IRQ support, the entire library should be built with TX_ENABLE_IRQ_NESTING +defined. With this defined, two new IRQ interrupt management services are +available, namely _tx_thread_irq_nesting_start and _tx_thread_irq_nesting_end. +These function should be called between the IRQ context save and restore +calls. + +Execution between the calls to _tx_thread_irq_nesting_start and +_tx_thread_irq_nesting_end is enabled for IRQ nesting. This is achieved +by switching from IRQ mode to SYS mode and enabling IRQ interrupts. +The SYS mode stack is used during the SYS mode operation, which was +setup in tx_initialize_low_level.S. When nested IRQ interrupts are no +longer required, calling the _tx_thread_irq_nesting_end service disables +nesting by disabling IRQ interrupts and switching back to IRQ mode in +preparation for the IRQ context restore service. + +The following is an example of enabling IRQ nested interrupts in a standard +IRQ handler: + + .global __tx_irq_handler + .global __tx_irq_processing_return +__tx_irq_handler: +@ +@ /* Jump to context save to save system context. */ + B _tx_thread_context_save +__tx_irq_processing_return: +@ +@ /* Enable nested IRQ interrupts. NOTE: Since this service returns +@ with IRQ interrupts enabled, all IRQ interrupt sources must be +@ cleared prior to calling this service. */ + BL _tx_thread_irq_nesting_start +@ +@ /* Application ISR call(s) go here! */ +@ +@ /* Disable nested IRQ interrupts. The mode is switched back to +@ IRQ mode and IRQ interrupts are disable upon return. */ + BL _tx_thread_irq_nesting_end +@ +@ /* Jump to context restore to restore system context. */ + B _tx_thread_context_restore + + +7.3 FIQ Interrupts + +By default, ARM7 FIQ interrupts are left alone by ThreadX. Of course, this +means that the application is fully responsible for enabling the FIQ interrupt +and saving/restoring any registers used in the FIQ ISR processing. To globally +enable FIQ interrupts, the application should enable FIQ interrupts at the +beginning of each thread or before any threads are created in tx_application_define. +In addition, the application must ensure that no ThreadX service calls are made +from default FIQ ISRs, which is located in tx_initialize_low_level.S. + + +7.3.1 Managed FIQ Interrupts + +Full ThreadX management of FIQ interrupts is provided if the ThreadX sources +are built with the TX_ENABLE_FIQ_SUPPORT defined. If the library is built +this way, the FIQ interrupt handlers are very similar to the IRQ interrupt +handlers defined previously. The following is default FIQ handler +defined in tx_initialize_low_level.S: + + + .global __tx_fiq_handler + .global __tx_fiq_processing_return +__tx_fiq_handler: +@ +@ /* Jump to fiq context save to save system context. */ + B _tx_thread_fiq_context_save +__tx_fiq_processing_return: +@ +@ /* At this point execution is still in the FIQ mode. The CPSR, point of +@ interrupt, and all C scratch registers are available for use. */ +@ +@ /* Application FIQ handlers can be called here! */ +@ +@ /* Jump to fiq context restore to restore system context. */ + B _tx_thread_fiq_context_restore + + +7.3.1.1 Nested FIQ Support + +By default, nested FIQ interrupt support is not enabled. To enable nested +FIQ support, the entire library should be built with TX_ENABLE_FIQ_NESTING +defined. With this defined, two new FIQ interrupt management services are +available, namely _tx_thread_fiq_nesting_start and _tx_thread_fiq_nesting_end. +These function should be called between the FIQ context save and restore +calls. + +Execution between the calls to _tx_thread_fiq_nesting_start and +_tx_thread_fiq_nesting_end is enabled for FIQ nesting. This is achieved +by switching from FIQ mode to SYS mode and enabling FIQ interrupts. +The SYS mode stack is used during the SYS mode operation, which was +setup in tx_initialize_low_level.S. When nested FIQ interrupts are no longer required, +calling the _tx_thread_fiq_nesting_end service disables nesting by disabling +FIQ interrupts and switching back to FIQ mode in preparation for the FIQ +context restore service. + +The following is an example of enabling FIQ nested interrupts in the +typical FIQ handler: + + + .global __tx_fiq_handler + .global __tx_fiq_processing_return +__tx_fiq_handler: +@ +@ /* Jump to fiq context save to save system context. */ + B _tx_thread_fiq_context_save +__tx_fiq_processing_return: +@ +@ /* At this point execution is still in the FIQ mode. The CPSR, point of +@ interrupt, and all C scratch registers are available for use. */ +@ +@ /* Enable nested FIQ interrupts. NOTE: Since this service returns +@ with FIQ interrupts enabled, all FIQ interrupt sources must be +@ cleared prior to calling this service. */ + BL _tx_thread_fiq_nesting_start +@ +@ /* Application FIQ handlers can be called here! */ +@ +@ /* Disable nested FIQ interrupts. The mode is switched back to +@ FIQ mode and FIQ interrupts are disable upon return. */ + BL _tx_thread_fiq_nesting_end +@ +@ /* Jump to fiq context restore to restore system context. */ + B _tx_thread_fiq_context_restore + + +8. ThreadX Timer Interrupt + +ThreadX requires a periodic interrupt source to manage all time-slicing, +thread sleeps, timeouts, and application timers. Without such a timer +interrupt source, these services are not functional but the remainder of +ThreadX will still run. + +To add the timer interrupt processing, simply make a call to +_tx_timer_interrupt in the IRQ processing.

Building the ThreadX run-time Library + +Building the ThreadX library is easy. First, open the Azure RTOS workspace +azure_rtos.eww. Next, make the TX project the "active project" in the +IAR Embedded Workbench and select the "Make" button. You should observe +assembly and compilation of a series of ThreadX source files. This +results in the ThreadX run-time library file tx.a, which is needed by +the application. + + +2. Demonstration System + +The ThreadX demonstration is designed to execute under the IAR +Windows-based ARM11 simulator. + +Building the demonstration is easy; simply make the sample_threadx.ewp project +the "active project" in the IAR Embedded Workbench and select the +"Make" button. + +You should observe the compilation of sample_threadx.c (which is the demonstration +application) and linking with tx.a. The resulting file sample_threadx.out is a +binary file that can be downloaded and executed on IAR's ARM11 simulator. + +A SPECIAL NOTE: The IAR ARM simulator does simulate interrupts. In order +for the ThreadX demonstration to run properly, a periodic IRQ interrupt must +be setup in the IAR debugging environment. We recommend setting an IRQ +interrupt to execute every 9999 cycles. + + +3. System Initialization + +The entry point in ThreadX for the ARM11 using IAR tools is at label +?cstartup. This is defined within the IAR compiler's startup code. In +addition, this is where all static and global preset C variable +initialization processing takes place. + +The ThreadX tx_initialize_low_level.s file is responsible for setting up +various system data structures, and a periodic timer interrupt source. +By default, the vector area is defined at the top of cstartup.s, which is +a slightly modified from the base IAR file. + +The _tx_initialize_low_level function inside of tx_initialize_low_level.s +also determines the first available address for use by the application, which +is supplied as the sole input parameter to your application definition function, +tx_application_define. To accomplish this, a section is created in +tx_initialize_low_level.s called FREE_MEM, which must be located after all +other RAM sections in memory. + + +4. Register Usage and Stack Frames + +The IAR ARM compiler assumes that registers r0-r3 (a1-a4) and r12 (ip) are +scratch registers for each function. All other registers used by a C function +must be preserved by the function. ThreadX takes advantage of this in +situations where a context switch happens as a result of making a ThreadX +service call (which is itself a C function). In such cases, the saved +context of a thread is only the non-scratch registers. + +The following defines the saved context stack frames for context switches +that occur as a result of interrupt handling or from thread-level API calls. +All suspended threads have one of these two types of stack frames. The top +of the suspended thread's stack is pointed to by tx_thread_stack_ptr in the +associated thread control block TX_THREAD. + + + + Offset Interrupted Stack Frame Non-Interrupt Stack Frame + + 0x00 1 0 + 0x04 CPSR CPSR + 0x08 r0 (a1) r4 (v1) + 0x0C r1 (a2) r5 (v2) + 0x10 r2 (a3) r6 (v3) + 0x14 r3 (a4) r7 (v4) + 0x18 r4 (v1) r8 (v5) + 0x1C r5 (v2) r9 (v6) + 0x20 r6 (v3) r10 (v7) + 0x24 r7 (v4) r11 (fp) + 0x28 r8 (v5) r14 (lr) + 0x2C r9 (v6) + 0x30 r10 (v7) + 0x34 r11 (fp) + 0x38 r12 (ip) + 0x3C r14 (lr) + 0x40 PC + + +5. Conditional Compilation Switches + +The following are conditional compilation options for building the ThreadX library +and application: + + + TX_ENABLE_FIQ_SUPPORT This assembler/compiler define enables + FIQ interrupt handling support in the + ThreadX assembly files. If used, + it should be used on all assembly + files and the generic C source of + ThreadX should be compiled with + TX_ENABLE_FIQ_SUPPORT defined as well. + + TX_ENABLE_IRQ_NESTING This assembler define enables IRQ + nested support. If IRQ nested + interrupt support is needed, this + define should be applied to + tx_initialize_low_level.s. + + TX_ENABLE_FIQ_NESTING This assembler define enables FIQ + nested support. If FIQ nested + interrupt support is needed, this + define should be applied to + tx_initialize_low_level.s. In addition, + IRQ nesting should also be enabled. + + TX_DISABLE_ERROR_CHECKING If defined before tx_api.h is included, + this define causes basic ThreadX error + checking to be disabled. Please see + Chapter 2 in the "ThreadX User Guide" + for more details. + + TX_MAX_PRIORITIES Defines the priority levels for ThreadX. + Legal values range from 32 through + 1024 (inclusive) and MUST be evenly divisible + by 32. Increasing the number of priority levels + supported increases the RAM usage by 128 bytes + for every group of 32 priorities. However, there + is only a negligible effect on performance. By + default, this value is set to 32 priority levels. + + TX_MINIMUM_STACK Defines the minimum stack size (in bytes). It is + used for error checking when threads are created. + The default value is port-specific and is found + in tx_port.h. + + TX_TIMER_THREAD_STACK_SIZE Defines the stack size (in bytes) of the internal + ThreadX timer thread. This thread processes all + thread sleep requests as well as all service call + timeouts. In addition, all application timer callback + routines are invoked from this context. The default + value is port-specific and is found in tx_port.h. + + TX_TIMER_THREAD_PRIORITY Defines the priority of the internal ThreadX timer + thread. The default value is priority 0 - the highest + priority in ThreadX. The default value is defined + in tx_port.h. + + TX_TIMER_PROCESS_IN_ISR Defined, this option eliminates the internal system + timer thread for ThreadX. This results in improved + performance on timer events and smaller RAM requirements + because the timer stack and control block are no + longer needed. However, using this option moves all + the timer expiration processing to the timer ISR level. + By default, this option is not defined. + + TX_REACTIVATE_INLINE Defined, this option performs reactivation of ThreadX + timers in-line instead of using a function call. This + improves performance but slightly increases code size. + By default, this option is not defined. + + TX_DISABLE_STACK_FILLING Defined, placing the 0xEF value in each byte of each + thread's stack is disabled. By default, this option is + not defined. + + TX_ENABLE_STACK_CHECKING Defined, this option enables ThreadX run-time stack checking, + which includes analysis of how much stack has been used and + examination of data pattern "fences" before and after the + stack area. If a stack error is detected, the registered + application stack error handler is called. This option does + result in slightly increased overhead and code size. Please + review the tx_thread_stack_error_notify API for more information. + By default, this option is not defined. + + TX_DISABLE_PREEMPTION_THRESHOLD Defined, this option disables the preemption-threshold feature + and slightly reduces code size and improves performance. Of course, + the preemption-threshold capabilities are no longer available. + By default, this option is not defined. + + TX_DISABLE_REDUNDANT_CLEARING Defined, this option removes the logic for initializing ThreadX + global C data structures to zero. This should only be used if + the compiler's initialization code sets all un-initialized + C global data to zero. Using this option slightly reduces + code size and improves performance during initialization. + By default, this option is not defined. + + TX_DISABLE_NOTIFY_CALLBACKS Defined, this option disables the notify callbacks for various + ThreadX objects. Using this option slightly reduces code size + and improves performance. + + TX_BLOCK_POOL_ENABLE_PERFORMANCE_INFO Defined, this option enables the gathering of performance + information on block pools. By default, this option is + not defined. + + TX_BYTE_POOL_ENABLE_PERFORMANCE_INFO Defined, this option enables the gathering of performance + information on byte pools. By default, this option is + not defined. + + TX_EVENT_FLAGS_ENABLE_PERFORMANCE_INFO Defined, this option enables the gathering of performance + information on event flags groups. By default, this option + is not defined. + + TX_MUTEX_ENABLE_PERFORMANCE_INFO Defined, this option enables the gathering of performance + information on mutexes. By default, this option is + not defined. + + TX_QUEUE_ENABLE_PERFORMANCE_INFO Defined, this option enables the gathering of performance + information on queues. By default, this option is + not defined. + + TX_SEMAPHORE_ENABLE_PERFORMANCE_INFO Defined, this option enables the gathering of performance + information on semaphores. By default, this option is + not defined. + + TX_THREAD_ENABLE_PERFORMANCE_INFO Defined, this option enables the gathering of performance + information on threads. By default, this option is + not defined. + + TX_TIMER_ENABLE_PERFORMANCE_INFO Defined, this option enables the gathering of performance + information on timers. By default, this option is + not defined. + + TX_ENABLE_EVENT_TRACE Defined, this option enables the internal ThreadX trace + feature. The trace buffer is supplied at a later time + via an application call to tx_trace_enable. + + TX_TRACE_TIME_SOURCE This defines the time-stamp source for event tracing. + This define is only pertinent if the ThreadX library is + built with TX_ENABLE_EVENT_TRACE defined. + + TX_TRACE_TIME_MASK This defines the number of valid bits in the event trace + time-stamp source defined previously. If the time-stamp + source is 16-bits, this value should be 0xFFFF. Alternatively, + if the time-stamp source is 32-bits, this value should be + 0xFFFFFFFF. This define is only pertinent if the ThreadX + library is built with TX_ENABLE_EVENT_TRACE defined. + + TX_THUMB Defined, this option enables the BX LR calling return sequence + in assembly files, to ensure correct operation on systems that + use both ARM and Thumb mode. By default, this option is + not defined + + + + + +6. Improving Performance + +The distribution version of ThreadX is built without any compiler +optimizations. This makes it easy to debug because you can trace or set +breakpoints inside of ThreadX itself. Of course, this costs some +performance. To make it run faster, you can change the ThreadX library +project to enable various compiler optimizations. + +In addition, you can eliminate the ThreadX basic API error checking by +compiling your application code with the symbol TX_DISABLE_ERROR_CHECKING +defined. + + +7. Interrupt Handling + +ThreadX provides complete and high-performance interrupt handling for ARM11 +targets. There are a certain set of requirements that are defined in the +following sub-sections: + + +7.1 Vector Area + +The ARM11 vectors start at address zero. The demonstration system startup +cstartup.s file contains the vectors and is loaded at address zero. +On actual hardware platforms, this area might have to be copied to address 0. + + +7.2 IRQ ISRs + +ThreadX fully manages standard and vectored IRQ interrupts. ThreadX also supports nested +IRQ interrupts. The following sub-sections define the IRQ capabilities. + + +7.2.1 Standard IRQ ISRs + +The standard ARM IRQ mechanism has a single interrupt vector at address 0x18. This IRQ +interrupt is managed by the __tx_irq_handler code in tx_initialize_low_level. The following +is the default IRQ handler defined in tx_initialize_low_level.s: + + PUBLIC __tx_irq_handler + PUBLIC __tx_irq_processing_return +__tx_irq_handler +; +; /* Jump to context save to save system context. */ + B _tx_thread_context_save +__tx_irq_processing_return +; +; /* At this point execution is still in the IRQ mode. The CPSR, point of +; interrupt, and all C scratch registers are available for use. Note +; that IRQ interrupts are still disabled upon return from the context +; save function. */ +; +; /* Application ISR dispatch call goes here! */ +; +; /* Jump to context restore to restore system context. */ + B _tx_thread_context_restore + + +7.2.2 Vectored IRQ ISRs + +The vectored ARM IRQ mechanism has multiple interrupt vectors at addresses specified +by the particular implementation. The following is an example IRQ handler defined in +tx_initialize_low_level.s: + + + RSEG .text:CODE:NOROOT(2) + PUBLIC __tx_example_vectored_irq_handler +__tx_example_vectored_irq_handler +; +; /* Jump to context save to save system context. */ + STMDB sp!, {r0-r3} ; Save some scratch registers + MRS r0, SPSR ; Pickup saved SPSR + SUB lr, lr, #4 ; Adjust point of interrupt + STMDB sp!, {r0, r10, r12, lr} ; Store other registers + BL _tx_thread_vectored_context_save +; +; /* At this point execution is still in the IRQ mode. The CPSR, point of +; interrupt, and all C scratch registers are available for use. Note +; that IRQ interrupts are still disabled upon return from the context +; save function. */ +; +; /* Application ISR dispatch call goes here! */ +; +; /* Jump to context restore to restore system context. */ + B _tx_thread_context_restore + + +7.2.3 Nested IRQ Support + +By default, nested IRQ interrupt support is not enabled. To enable nested +IRQ support, the entire library should be built with TX_ENABLE_IRQ_NESTING +defined. With this defined, two new IRQ interrupt management services are +available, namely _tx_thread_irq_nesting_start and _tx_thread_irq_nesting_end. +These function should be called between the IRQ context save and restore +calls. + +Execution between the calls to _tx_thread_irq_nesting_start and +_tx_thread_irq_nesting_end is enabled for IRQ nesting. This is achieved +by switching from IRQ mode to SYS mode and enabling IRQ interrupts. +The SYS mode stack is used during the SYS mode operation, which was +setup in tx_initialize_low_level.s. When nested IRQ interrupts are no +longer required, calling the _tx_thread_irq_nesting_end service disables +nesting by disabling IRQ interrupts and switching back to IRQ mode in +preparation for the IRQ context restore service. + +The following is an example of enabling IRQ nested interrupts in a standard +IRQ handler: + + RSEG .text:CODE:NOROOT(2) + PUBLIC __tx_irq_handler + RSEG .text:CODE:NOROOT(2) + PUBLIC __tx_irq_processing_return +__tx_irq_handler +; +; /* Jump to context save to save system context. */ + B _tx_thread_context_save +__tx_irq_processing_return +; +; /* At this point execution is still in the IRQ mode. The CPSR, point of +; interrupt, and all C scratch registers are available for use. Note +; that IRQ interrupts are still disabled upon return from the context +; save function. */ +; +; /* Interrupt nesting is allowed after calling _tx_thread_irq_nesting_start +; from IRQ mode with interrupts disabled. This routine switches to the +; system mode and returns with IRQ interrupts enabled. +; +; NOTE: It is very important to ensure all IRQ interrupts are cleared +; prior to enabling nested IRQ interrupts. */ +; + BL _tx_thread_irq_nesting_start + +; /* Application ISR dispatch call goes here! */ +; +; /* If interrupt nesting was started earlier, the end of interrupt nesting +; service must be called before returning to _tx_thread_context_restore. +; This routine returns in processing in IRQ mode with interrupts disabled. */ +; + BL _tx_thread_irq_nesting_end +; +; /* Jump to context restore to restore system context. */ + B _tx_thread_context_restore + + +7.3 FIQ Interrupts + +By default, ARM11 FIQ interrupts are left alone by ThreadX. Of course, this +means that the application is fully responsible for enabling the FIQ interrupt +and saving/restoring any registers used in the FIQ ISR processing. To globally +enable FIQ interrupts, the application should enable FIQ interrupts at the +beginning of each thread or before any threads are created in tx_application_define. +In addition, the application must ensure that no ThreadX service calls are made +from default FIQ ISRs, which is located in tx_initialize_low_level.s. + + +7.3.1 Managed FIQ Interrupts + +Full ThreadX management of FIQ interrupts is provided if the ThreadX sources +are built with the TX_ENABLE_FIQ_SUPPORT defined. If the library is built +this way, the FIQ interrupt handlers are very similar to the IRQ interrupt +handlers defined previously. The following is default FIQ handler +defined in tx_initialize_low_level.s: + + + RSEG .text:CODE:NOROOT(2) + PUBLIC __tx_fiq_handler + RSEG .text:CODE:NOROOT(2) + PUBLIC __tx_fiq_processing_return +__tx_fiq_handler +; +; /* Jump to fiq context save to save system context. */ + B _tx_thread_fiq_context_save +__tx_fiq_processing_return: +; +; /* At this point execution is still in the FIQ mode. The CPSR, point of +; interrupt, and all C scratch registers are available for use. */ +; +; /* Application FIQ dispatch call goes here! */ +; +; /* Jump to fiq context restore to restore system context. */ + B _tx_thread_fiq_context_restore + + + +7.3.1.1 Nested FIQ Support + +By default, nested FIQ interrupt support is not enabled. To enable nested +FIQ support, the entire library should be built with TX_ENABLE_FIQ_NESTING +defined. With this defined, two new FIQ interrupt management services are +available, namely _tx_thread_fiq_nesting_start and _tx_thread_fiq_nesting_end. +These function should be called between the FIQ context save and restore +calls. + +Execution between the calls to _tx_thread_fiq_nesting_start and +_tx_thread_fiq_nesting_end is enabled for FIQ nesting. This is achieved +by switching from FIQ mode to SYS mode and enabling FIQ interrupts. +The SYS mode stack is used during the SYS mode operation, which was +setup in tx_initialize_low_level.s. When nested FIQ interrupts are no +longer required, calling the _tx_thread_fiq_nesting_end service disables +nesting by disabling FIQ interrupts and switching back to FIQ mode in +preparation for the FIQ context restore service. + +The following is an example of enabling FIQ nested interrupts in the +typical FIQ handler: + + + RSEG .text:CODE:NOROOT(2) + PUBLIC __tx_fiq_handler + RSEG .text:CODE:NOROOT(2) + PUBLIC __tx_fiq_processing_return +__tx_fiq_handler +; +; /* Jump to fiq context save to save system context. */ + B _tx_thread_fiq_context_save +__tx_fiq_processing_return: +; +; /* At this point execution is still in the FIQ mode. The CPSR, point of +; interrupt, and all C scratch registers are available for use. */ +; +; /* Enable nested FIQ interrupts. NOTE: Since this service returns +; with FIQ interrupts enabled, all FIQ interrupt sources must be +; cleared prior to calling this service. */ + BL _tx_thread_fiq_nesting_start +; +; /* Application FIQ dispatch call goes here! */ +; +; /* Disable nested FIQ interrupts. The mode is switched back to +; FIQ mode and FIQ interrupts are disable upon return. */ + BL _tx_thread_fiq_nesting_end +; +; /* Jump to fiq context restore to restore system context. */ + B _tx_thread_fiq_context_restore + + +8. ThreadX Timer Interrupt + +ThreadX requires a periodic interrupt source to manage all time-slicing, +thread sleeps, timeouts, and application timers. Without such a timer +interrupt source, these services are not functional. However, all other +ThreadX services are operational without a periodic timer source. + +To add the timer interrupt processing, simply make a call to _tx_timer_interrupt +in the IRQ processing. + + +9. Thumb/ARM11 Mixed Mode + +By default, ThreadX is setup for running in ARM11 32-bit mode. This is +also true for the demonstration system. It is possible to build any +ThreadX file and/or the application in Thumb mode. The only exception +to this is the file tx_thread_shell_entry.c. This file must always be +built in 32-bit mode. In addition, if any Thumb code is used the entire +ThreadX assembly source should be built with TX_THUMB defined. + + +10. IAR Thread-safe Library Support + +Thread-safe support for the IAR tools is easily enabled by building the ThreadX library +and the application with TX_ENABLE_IAR_LIBRARY_SUPPORT. Also, the linker control file +should have the following line added (if not already in place): + +initialize by copy with packing = none { section __DLIB_PERTHREAD }; // Required in a multi-threaded application + +The project options "General Options -> Library Configuration" should also have the +"Enable thread support in library" box selected. + + +11.
