The CorePac Memory Management Unit (CMMU) extends the C71x architecture with support for address translation, access permission and protections and memory attributes determination and checking. It is implemented per C71x cluster as a two-level TLB structure. The CMMU works with the C71x L1 caches, stream buffers in each processor and CorePac memory system of CorePac cluster to translate virtual addresses to physical addresses, controls tablewalk hardware that accesses translation tables in main memory. The CMMU enables fine-grained memory system control through a set of virtual-to-physical address mappings and memory attributes held in the L1 level micro translation look-aside buffer (uTLB) and CorePac cluster level translation look-aside buffers (TLBs).
The CMMU provides the following key features:
