关于CPPI 中的Link Ram和index的计算问题



Hi 大家好

我看CPPI时看到这个图有些不太明白,首先,按照CPPI的datasheet说Link Ram的base address是用来计算descriptor 的index值的,那么这个index的值怎么通过Link ram 的 base address计算出来呢?还有就是按照下图来理解的话对于index 0-9,base address应该是region 1的起始地址啊,对于index 0-9,其index=(descriptor的地址-region1的base address)/64+起始的index(对于region1就是0)。这么理解对不对?请专家解答,谢谢
