# perf_counter (v2.1.0-dev)
# perf_counter (v2.1.0)
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:
- **Measure CPU cycles for specified code segment**
- **[NEW] Add Coremark 1.0**
- **Add Coremark 1.0**
- **[New] Provide Timer Service for EventRecorder automatically.**
- **Enhanced measurement services for RTOS**
- Measures **RAW / True** cycles used for specified code segment inside a thread, **i.e. scheduling cost are removed**.
- Measure **RAW/True** cycles used for a data-process-path across multiple threads.
- **Easy to use**
- Helper macros: `__cycleof__()` , `__super_loop_monitor__()` etc.
- Helper functions: `start_cycle_counter()`, `stop_cycle_counter()` etc.
- **Support ALL Cortex-M processors**
- Including **Cortex-M85** and Star-MC1
- **Provide Free Services**
- Do **NOT** interfering with existing SysTick based applications
- **Support ALL arm compilers**
- Arm Compiler 5 (armcc), Arm Compiler 6 (armclang)
- arm gcc

### 1.3 Work with EventRecorder in MDK
If you are using EventRecorder in MDK, once you deployed the `perf_counter`, it will provide the timer service for EventRecorder by implenting the following functions: `EventRecorderTimerSetup()`, `EventRecorderTimerGetFreq()` and `EventRecorderTimerGetCount()`.
If you have not modify anything in `EventRecorderConf.h`, **you don't have to anything** and please keep the default configuration. If you see warnings like this:
```
Invalid Time Stamp Source selected in EventRecorderConf.h!
```
Please ignore it, or you can set the macro `EVENT_TIMESTAMP_SOURCE` to `3` to suppress it.
**By using perf_counter as the reference clock, EventRecorder can have the highest clock resolution on the target system without worring about the presence of DWT or any conflicting usage of SysTick.**
