block-inclusivecache-sifive

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. 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.
