Abstract:
A pipelined cache memory supports global operations within the cache. The cache may be a spiral cache, with a move-to-front M2F network for moving values from a backing store to a front-most tile coupled to a processor or lower-order level of a memory hierarchy and a spiral push-back network for pushing out modified values to the backing-store. The cache controller manages application of global commands by propagating individual commands to the tiles. The global commands may provide zeroing, flushing and reconciling of the given tiles. Commands for interrupting and resuming interrupted global commands may be implemented, to reduce halting or slowing of processing while other global operations are in process. A line detector within each tile supports reconcile and flush operations, and a line patcher in the controller provides for initializing address ranges with no processor intervention.
