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：

        (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


    CSV, Benchmark, Iterations, Cycles, CoreMark/MHz
    CSV, CoreMark, 8000, 2327708283, 3.436
    IPC = Instret/Cycle = 1807000296/2327708283 = 0.776
