C6678的semaphore2的有效核问题？

easy super
Prodigy 100 points


在semaphore的user guide中“The module supports up to 64 semaphores that can be accessed by all four cores.”和SEMFLAG Registers (0 – N)N=0～3.

为什么是4个core怎么使用？为什么不是1个或8个？

对应的csl库中的masterID又有什么用？

与c66的corepac数量什么关系？

谢谢

    以数据手册为准，8个核都可以访问semaphore2.
    The semaphore module supports 8 masters and contains 32 semaphores to be used within the system.

    masterID表示核号
    The semaphore module is accessible only by masters with privilege ID (privID) 0 to 7, which means only CorePac 0 to 7 or the EDMA transactions initiated by CorePac 0 to 7 can access the semaphore module.
