# perf_counter (v1.9.8) # perf_counter (v1.9.9)
A dedicated performance counter for Cortex-M Systick. It shares the SysTick with users' original SysTick function(s) without interfering with it. This library will bring new functionalities, such as performance counter,` delay_us` and `clock()` service defined in `time.h`. A dedicated performance counter for Cortex-M Systick.
