前言

根据官方的手册宣传可以看到coremark跑分达到了4925,我们就实际测一测。

准备

基于WIN11下的WSL2搭建开发环境

安装WSL2和Ubuntu20.04,过程可以搜索网络上的资料,这里不再赘述。

打开WSL终端

安装编译器

sudo apt-get install gcc-aarch64-linux-gnu

查看编译器版本

aarch64-linux-gnu-gcc -v

过程

下载代码

git clone https://github.com/eembc/coremark.git

cd coremark/

vi simple/core_portme.h

修改

#define COMPILER_FLAGS \

    FLAGS_STR /* "Please put compiler flags here (e.g. -o3)" */

#endif

为

#define COMPILER_FLAGS \

    "-O3" /* "Please put compiler flags here (e.g. -o3)" */

#endif

如果-O0编译则改为”-O0”

typedef ee_u32 ee_ptr_int;

改为

typedef unsigned long ee_ptr_int;

编译

aarch64-linux-gnu-gcc core_list_join.c core_main.c core_matrix.c core_state.c core_util.c simple/core_portme.c -DPERFORMANCE_RUN=1 -DITERATIONS=100000 -Isimple -I. -O0 -o coremarko0

aarch64-linux-gnu-gcc core_list_join.c core_main.c core_matrix.c core_state.c core_util.c simple/core_portme.c -DPERFORMANCE_RUN=1 -DITERATIONS=100000 -Isimple -I. -O3 -o coremarko3

aarch64-linux-gnu-gcc core_list_join.c core_main.c core_matrix.c core_state.c core_util.c simple/core_portme.c -DPERFORMANCE_RUN=1 -DITERATIONS=100000 -Isimple -I. -ofast -o coremarkofast

导入到windows下

cp coremarko0 coremarko3 coremarkofast /mnt/d

然后通过串口rz导入到开发板

添加可执行权限

chmod +x coremarko0 coremarko3 coremarkofast

运行

echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor切换到性能模式

./coremarko0

./coremarko3

./coremarkofast

结果如下,可以看到优化不同差距较大

与官方的4952差别不大

用官方的程序跑也是4628,所以与板子本身环境还有一些影响。
