# perf_counter (v1.9.8)
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`.
### Features:

Implement an empty funciton `__ensure_systick_wrapper()` as there is no wrapper actually used in this deployment method:
```c
void __ensure_systick_wrapper(void)
{
}
```
7. Make sure the `SystemCoreClock` is updated with the same value as CPU frequency.
