STM32U385RG属 STM32 超低功耗家族，基于 96MHz 高性能 Arm® Cortex®-M33 内核，集成 TrustZone 和 FPU 单元。片载 1MB Flash、256KB SRAM 。搭载 Arm® Cortex®-M33 内核，主频高达 96 MHz。看着这些性能参数，还是不错了，
因此特别想测试一下STM32U385RG的跑分性能，看看到底在什么水平！
因为，我们需要下载开源的跑分测试软件coremark
https://github.com/eembc/coremark
大家可以在github上进行下载
 

 

这里面文件很多，我们只需要这几个文件就可以
 

 

新建一个coremark文件夹，将这些文件放在里面
 

添加路劲
 

添加源文件
 

设置最大优化等级，-Omax
 

修改coremark源代码
 

 

 

添加systick时间函数
 

 

核心函数如下

打开串口助手
 

等待跑分完毕
 

最终在96MHZ，最大优化等级 -Omax条件下，
STM32U385RG 的coremark跑分为288.658603分。
这个分数算一般吧，和STM32F407比有很大的差距
