CoreMark

概述

CoreMark示例工程展示了运行CoreMark测试程序的情况。

硬件设置

无特殊设置

运行现象

当工程正确运行后，串口终端会输出CoreMark测试结果：

CoreMark 1.0 : 687.371393 / GCC14.2.1 20240816 -Ofast -fno-code-hoisting -fno-common -finline-functions -falign-functions=6 -falign-jumps=6

    (Iterations is: 8000
    (total_ticks is: 2327708283
(*) Assume the core running at 1 MHz
    So the CoreMark/MHz can be calculated by:
    (Iterations*1000000/total_ticks) = 3.436857 CoreMark/MHz
