 ### 2. CoreMark CoreMark is a benchmark program used to evaluate CPU performance. It includes a variety of different computing tasks, including floating point, integer, cache, memory and other aspects. CoreMark test results are usually used as a reference for CPU performance. It can help developers and system administrators evaluate the performance of different processors and systems, compare the performance differences between different processors, and can also be used to test the performance of processors in multi-threaded parallel computing. Official website: https://www.eembc.org/ Github repository address: https://github.com/eembc/coremark Among them, simple is the interface transplantation file, which is more important. Important modifications are made here. The following core_main.c, core_matrix.c and other files are important files for testing

 ### 3. CoreMark transplantation 1. Make modifications to the project that supports printf and build your own project template, mainly modifying the path and establishing the at32a403a_coremark_tempalte project template.

 4. Modify the content of the core_portme.c file 1. Modify some macro definitions The value of ITERATIONS depends on the situation. If **ERROR! Must execute for at least 10 secs for a valid result!** appears, then you need to change this value to make the program run time at least 10 seconds. ```c #define SysTick_Counter_Disable ((uint32_t)0xFFFFFFFE) #define SysTick_Counter_Enable ((uint32_t)0x00000001) #define SysTick_Counter_Clear ((uint32_t)0x00000000) __IO uint32_t Ticks; #define ITERATIONS 500 0; ``` 2. Shield part of the code ```c //#define NSECS_PER_SEC CLOCKS_PER_SEC //#define CORETIMETYPE clock_t //#define GETMYTIME(_t) (*_t = clock()) //#define MYTIMEDIFF(fin, ini) ((fin) - (ini)) //#define TIMER_RES_DIVIDER 1 //#define SAMPLE_TIME_IMPLEMENT ATION 1 //#define EE_TICKS_PER_SEC (NSECS_PER_SEC / TIMER_RES_DIVIDER) /** Define Host specific (POSIX), or target specific global time variables. */ //static CORETIMETYPE start_time_val, stop_time_val;//changed ```` 3. Add start_time, stop_time, get_time function body, mainly for time timing ```c __IO uint32_t Ticks; /* Function : start_time This function will be called right before starting the timed portion of the benchmark. Implementation may be capturing a system timer (as implemented in the example code) or zeroing some system parameters - eg setting the cpu clocks cycles to 0. */ void start_time(void)//changed { //GETMYTIME(&start_time_val); Ticks++; SysTick_Config(SystemCoreClock / 1000); //1ms interrupt} /* Function: stop_time This function will be called right after ending the timed portion of the benchmark. Implementation may be capturing a system timer (as implemented in the example code) or other system parameters - eg reading the current value of cpu cycles counter.*/
  void stop_time(void)//changed
  {
    //GETMYTIME(&stop_time_val);
      /* Stop the Timer and get the encoding time */
     SysTick->CTRL &=SysTick_Counter_Disable;
     /* Clear the SysTick Counter */
     SysTick->VAL = SysTick_Counter_Clear;
  }
  /* Function : get_time
    Return an abstract "ticks" number that signifies time on the system.
  
    Actual value returned may be cpu cycles, milliseconds or any other
   value, as long as it can be converted to seconds by<time_in_secs>. This
   methodology is taken to accomodate any hardware or simulated platform. The
   sample implementation returns millisecs by default, and the resolution is
   controlled by <timer_res_divider>
  */ CORE_TICKS get_time(void)//changed { CORE_TICKS elapsed=(CORE_TICKS) Ticks;//(MYTIMEDIFF(stop_time_val, start_time_val)); return elapsed; } ``` You need to add the following code in the interrupt service function```c extern __IO uint32_t Ticks; void SysTick_Handler(void) { Ticks++; } ``` 4. Perform chip initialization functions (such as system clock, serial port configuration) in the portable_init function ```c /* Function : portable_init Target specific initialization code Test for some common mistakes. */ void portable_init(core_portable *p, int *argc, char *argv[]) { system_clock_config(); delay_init(); uart_print_init(115200); printf("at32a403a_board hardware_init [ok] _portme.c /* Copyright 2018 Embedded Microprocessor Benchmark Consortium (EEMBC) Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.

5. 由于原工程有main函数，core_main也有main函数，则需要注释吊main.c的函数。
