CoreMark简介

  • 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。
