RA8D1 coremark跑分测试

首先，来个美女镇楼吧，最近在健身中！！！

很荣幸收到了瑞萨电子发放的CPKCOR-RA8D1B开发板, RA8D1是瑞萨的Arm® Cortex®-M85 core旗舰版M85处理器，是专门用来跑AI算法的MCU，加上480MHZ的主频，性能应该非常的强劲，所以本期就使用coremark来对RA8D1进行跑分测试。看看能跑多少分！！！

1。首先从官网下载coremark源代码

https://github.com/eembc/coremark
大家自行下载

2。新建工程，使用瑞萨的ra smart配置软件建立串口工程，这里就不赘述了，直接看我上一篇测评文章，里面有详细说明

3。修改coremark源文件

如上图所示，只需要上面的文件

#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"// ��ֵ��ʵ�ʵı��Ż�ѡ��д
#endif

#ifndef MEM_LOCATION
#define MEM_LOCATION "STACK"
#endif

#define ITERATIONS 10000 // ��ֵ��Ҫ��֤�ܹ��10�룬��дһ��ֵ��в��10��ᱨ��ٻ��޸�
#define MAIN_HAS_NOARGC 1 // coremark main��ʹ�÷��ֵ

使能最高优化等级，跑分最高

同时KEIL里面也要使能-Omax等级

修改上面的宏定义

4。主要核心代码如下：
#include "hal_data.h"
#include "Systick.h"
#include "usart9.h"
#include "usart_ring.h"
#include "bsp_debug_uart.h"
#include "bsp_canfd1.h"
#include "coremark.h"

FSP_CPP_HEADER
void R_BSP_WarmStart(bsp_warm_start_event_t event);
FSP_CPP_FOOTER

extern MAIN_RETURN_TYPE coremark_main(void);

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

hal_systick_init();

printf("RA8D1测试版coremark跑分\r\n");
coremark_main();

while (1)
{
HAL_Delay(200);

}

#if BSP_TZ_SECURE_BUILD
/* Enter non-secure code */
R_BSP_NonSecureEnter();
#endif
}

void R_BSP_WarmStart (bsp_warm_start_event_t event)
{
if (BSP_WARM_START_RESET == event)
{
#if BSP_FEATURE_FLASH_LP_VERSION != 0
```
/* Enable reading from data flash. */
 R_FACI_LP->DFLCTL = 1U;

 /* Would normally have to wait tDSTOP(6us) for data flash recovery. Placing the enable here, before clock and
  * C runtime initialization, should negate the need for a delay since the initialization will typically take more than 6us. */
```

#endif
}

if (BSP_WARM_START_POST_C == event)
{
    /* C runtime environment and system clocks are setup. */

    /* Configure pins. */
    R_IOPORT_Open(&g_ioport_ctrl, &IOPORT_CFG_NAME);
}

}

#if BSP_TZ_SECURE_BUILD

FSP_CPP_HEADER
BSP_CMSE_NONSECURE_ENTRY void template_nonsecure_callable ();

/* Trustzone Secure Projects require at least one nonsecure callable function in order to build (Remove this if it is not required to build). */
BSP_CMSE_NONSECURE_ENTRY void template_nonsecure_callable ()
{

}
