This block package contains an RTL generator for creating instances of a coherent, last-level, inclusive cache.
The InclusiveCache controller enforces coherence among a set of caching clients
using an invalidation-based coherence policy implemetated on top of the the TileLink 1.8.1 coherence messaging protocol.
This policy is implemented using a full-map of directory bits stored with each cache block's metadata tag.
The InclusiveCache is a TileLink adapter;
it can be used as a drop-in replacement for Rocket-Chip's tilelink.BroadcastHub coherence manager.
It additionally supplies a SW-controlled interface for flusing cache blocks based on physical addresses.
The following parameters of the cache are easily Config-urable:
size, ways, banking and sub-banking factors, external bandwidth, network interface buffering.
Stand-alone unit tests coming soon.
