coremark

coremark是专业用来评估MCU单片机性能的第三方开源软件库。
本期就来移植coremark到RA4E2来测试一下coremark的跑分性能！！！！！！

1。首先从coremark官网下载coremark源码。

2。下载后，复制下面文件到一个文件夹内

3。打开之前创建好的串口工程，将coremark添加到KEIL工程里

4。修改主要核心代码

#ifndef COMPILER_VERSION
#ifdef GNUC
#define COMPILER_VERSION "GCC"VERSION
#else
#define COMPILER_VERSION "Please put compiler version here (e.g. gcc 4.1)"
#endif
#endif
#ifndef COMPILER_FLAGS
#define COMPILER_FLAGS "-Omax"// 这个值根据实际的编译优化选项进行填写
#endif

#ifndef MEM_LOCATION
#define MEM_LOCATION "STACK"
#endif

选取最大优化等级，Omax，对应KEIL里

主函数如下：
#include "hal_data.h"
#include "usart9.h"
#include "shell.h"
#include "ebtn_app.h"
#include "Serial.h"
#include "coremark.h"

FSP_CPP_HEADER
void R_BSP_WarmStart(bsp_warm_start_event_t event);
FSP_CPP_FOOTER
extern void coremark_main(void);

/*******************************************************************************************************************//**

main() is generated by the RA Configuration editor and is used to generate threads if an RTOS is used. This function

*********************************************************************************************************************/
void hal_entry(void)
{
/ TODO: add your own code here */
UART9_Init();hal_systick_init();
shell_init();
ebtn_APP_Key_INIT();

printf("\r\n>RA4E2性能跑分coremark分数\r\n");

coremark_main();

while(1)
{
SerialDecode();
/*

led1_off();led2_on();HAL_Delay(200);
break;
case 5:

break;
default:

break;
}
