如何利用MicroBlaze实现大内部存储器设计

MicroBlaze可以使用AXI BRAM存放数据和指令。有些客户软件很大，需要把AXI BRAM的空间做到最大。AXI BRAM底层是Block RAM或者Ultra RAM。器件的Block RAM或者Ultra RAM个数，决定了AXI BRAM的大小。

在ZCU106单板上，有312个Block RAM，有96个Ultra RAM。客户需要1MB存储空间。实现MicroBlaze时，也使用Block RAM实现Cache，和Local Memory。剩下的个Block RAM不够做1MB的AXI BRAM。为了实现1MB空间，可以用Block RAM实现512KB AXI BRAM、256KB AXI BRAM；再使用Ultra RAM实现256KB AXI BRAM。为这三个AXI BRAM分配连续的地址空间，从而使软件感觉到这是一个存储器。其中，Block RAM和Ultra RAM还可以根据实际情况调整，比如用Block RAM实现512KB AXI BRAM；用Ultra RAM实现512KB AXI BRAM，两个存储器也可以实现1MB存储空间。
