GorgonMeducer perf_counter A dedicated performance counter for the Cortex-M Systick. It shares the SysTick with users' original SysTick function without interfering with it. This library will bring new functionalities, such as performance counter, APIs for delay, clock() defined in time.h etc. https://raw.githubusercontent.com/GorgonMeducer/perf_counter/CMSIS-Pack/cmsis-pack/ https://github.com/GorgonMeducer/perf_counter/issues lib/LICENSE https://github.com/GorgonMeducer/perf_counter.git Active development ... - Add support for RT-Thread-nano - Add an API for checking stack overflow - Improve the support for the Arm Compiler 6.21 - Other minor updates - Mitigate time-rolling-back issue when calling get_system_ticks in exception handlers that have higher priorities than the SysTick_Handler. - Other minor updates - Add __cpu_time__ - Support reconfiguring the SysTick - Suppress warnings - Other minor updates - Update perfc_is_time_out_ms and perf_is_time_out_us - Enhance Timer Services - Other minor changes - Update stop_cycle_counter prototype to solve return-value-overflow issue - Provide timer service for EventRecorder automatically - Remove the bundle from cmsis-pack - Add Coremark - Fix the source variant support for Armv8-M processors - Other minor fixes - Fix the support for RT-Thread - Improve the way to import systick wrapper - Add get_system_us to avoid 64bit integer divider. - Minor Update - Improve delay accuracy - Fix RT-Thread stack-fully-used issue - introduce macro __PERF_COUNTER_CFG_USE_SYSTICK_WRAPPER__ - Add RT-Thread Package - Add new API update_perf_counter() for notifying perf_counter that SystemCoreClock has been updated - Add a macro __perf_counter_printf__ to retarget printf - Add a macor __PERF_COUNT_PLATFORM_SPECIFIC_HEADER__ for people to insert a platform specific header file. - Add Doxygen - Other minor changes - Add support for Cortex-M85, Star-MC1 and all other Armv8.1-M processors - Update Readme - Mitigate some clang warnings - Minor update for RTOS support - Fix CONNECT macro cannot connect two parameters issue. - Add UNUSED_PARAM - Add support for C++ env - Other minor updates - Add API get_system_ms() to avoid int64_t divide operation. - Add API delay_ms() - Add preprocessing in perf_counter.h to detect whether GNU extension is enabled or not. - Enhance RTOS support - Add macro __PERF_COUNTER__ in RTE_Components.h for compile-time detection. - Fix a bug found in __cycleof__. The __cycle_counter__ was not updated with the measure result. - Add macros for version info. Cortex-M SysTick Performance Analaysis Arm Compiler 5 (armcc) or Arm Compiler 6 (armclang).
