zhaomeijing@raspberrypi5:~$1.2 CoreMark性能测试
1.2.1 CoreMark简介//------CoreMark简介CoreMark是用来衡量嵌入式系统中心处理单元（CPU，或叫做微控制器MCU）性能的标准。该标准于2009年由EEMBC组织的Shay Gla-On提出，并且试图将其发展成为工业标准，从而代替陈旧的Dhrystone标准。代码使用C语言写成，包含如下的运算法则：列举（寻找并排序），数学矩阵操作（普通矩阵运算）和状态机（用来确定输入流中是否包含有效数字），最后还包括CRC（循环冗余校验）。CoreMark是由EEMBC(Embedded Microprocessor Benchmark Consortium)的Shay Gla-On于2009年提出的一项基准测试程序，CoreMark的主要目标是简化操作，并提供一套测试单核处理器核心的方法。测试标准是在配置参数的组合下单位时间内运行的CoreMark程序次数（单位：CoreMark/MHz），该数字值越大则说明测试的性能越好。目前在嵌入式CPU行业中普遍公认的性能测试指标的标准主要使用以下三种，MIPS、Dhrystone、Coremark，而CoreMark与Dhrystone一样，拥有体积小、方便移植、易于理解、免费并且显示单个数字基准分数。与Dhrystone不同的是，Dhrystone的主要部分实际上暴露了编译器优化工作负载的能力，而不是实际MCU或CPU的能力，的性能，而CoreMark具有特定的运行和报告规则，从而可以避免由于所使用的编译库不同而导致的测试结果难以比较。1.2.2 CoreMark源码获取与编译//------CoreMark源码获取EEMBC 在将 CoreMark 源码托管在 GitHub 上可以访**ithub.com/eembc/coremark直接点击下载获得源码；也可以通过 git 命令下载到本地。//------CoreMark源码获取
