以下是测评用户编写的测评内容，欢迎阅读：

前言

之前进行了开发环境的体验，现在对各方面的性能进行一个定性体验。

跑分

打开WSL终端

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

export PATH=$PATH:~/lichee/out/sun8iw11p1/linux/common/buildroot/host/usr/bin

arm-linux-gnueabihf-gcc -o coremarko0 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

arm-linux-gnueabihf-gcc -o coremarko3 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

导入到windows下

cp coremarko0 coremarko3 /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

运行

./coremarko0

./coremarko3

结果如下,可以看到优化不同差距较大

RAM性能测试

WSL中

下载代码

git clone https://github.com/qinyunti/STREAM.git

cd STREAM/

编译

export PATH=$PATH:~/lichee/out/sun8iw11p1/linux/common/buildroot/host/usr/bin

arm-linux-gnueabihf-gcc -O3 -DSTREAM_ARRAY_SIZE=5000000 stream.c -o stream.5M

导出到windows下

cp stream.5M /mnt/d

然后通过串口rz导入到开发板

添加可执行权限

chmod +x stream.5M

运行

./stream.5M

结果如下

root@T3/A40i-Tronlong:~# ./stream.5M

-------------------------------------------------------------

STREAM version $Revision: 5.10 $

-------------------------------------------------------------

This system uses 8 bytes per array element.

-------------------------------------------------------------

Array size = 5000000 (elements), Offset = 0 (elements)

Memory per array = 38.1 MiB (= 0.0 GiB).

Total memory required = 114.4 MiB (= 0.1 GiB).

Each kernel will be executed 10 times.

The *best* time for each kernel (excluding the first iteration)

will be used to compute the reported bandwidth.

-------------------------------------------------------------

Your clock granularity/precision appears to be 1 microseconds.

Each test below will take on the order of 52219 microseconds.

(= 52219 clock ticks)

Increase the size of the arrays if this shows that

you are not getting at least 20 clock ticks per test.

-------------------------------------------------------------

WARNING -- The above is only a rough guideline.

For best results, please be sure you know the

precision of your system timer.

-------------------------------------------------------------

Function Best Rate MB/s Avg time Min time Max time

RAM压力测试

参考 https://pyropus.ca./software/memtester/

WSL中

下载代码

wget https://pyropus.ca./software/memtester/old-versions/memtester-4.5.1.tar.gz

tar -xvf memtester-4.5.1.tar.gz

cd memtester-4.5.1/

编译

export PATH=$PATH:~/lichee/out/sun8iw11p1/linux/common/buildroot/host/usr/bin

arm-linux-gnueabihf-gcc -O3 memtester.c tests.c -o memtester

导出到WINDOWS下,下载到开发板

cp memtester /mnt/d

chmod +x memtester

运行

./memtester

运行结果如下,默认一直测试下去,可以最后指定测试次数

比如

./memtester 128M 1

128M表示测试RAM大小

1表示测试一次

另外也可以-p直接指定物理地址,适合在板子开发阶段裸机代码直接指定物理地址测试。

速度和SD卡本身有关，也没有考虑缓存，所以结果仅作参考。

总结

以上综合对性能进行了测试,感觉性能还是非常不错的，各测试结果仅作参考，因为环境等因素不一样测得结果也会不一样，包括存储的测试方法也不是很科学，比如没有考虑缓存等。上述测试只是一个定性的性能体验，板子的性能是一个综合的体验，需要是面对真实的应用场景才有意义，并且针对场景优化也很重要。
