Console Coremark 示例
======================================

概览
------

多核 命令上终端 Coremark 示例同时在核０和核１上跑 "coremark"并将结果打印到终端

开发板设置
---------------

BOOT_PIN 必须拨到 0-OFF, 1-OFF

生成、编译和调试多核工程
------------------------------------

请参见 :ref:`Multicore 通用说明 <multicore_general_description>`

运行现象
------------

- 以HPM6750EVKMINI为例，当该程序正确运行时，会打印类似如下示例


.. code-block:: console
