CACHE SYSTEM FOR MANAGING VARIOUS CACHE LINE CONDITIONS

摘要

A cache controller configured to detect a wait type (i.e., a wait event) associated with an imprecise collision and/or contention event is disclosed. The cache controller is configured to operatively connect to a cache memory device, which is configured to store a plurality of cache lines. The cache controller is configured to detect a wait type due to an imprecise collision and/or collision event associated with a cache line. The cache controller is configured to cause transmission of a broadcast to one or more transaction sources (e.g., broadcast to the transaction sources internal to the cache controller) requesting the cache line indicating the transaction source can employ the cache line.
