Title: PREFETCHING DATA IN COMPUTER SYSTEM
Abstract:
A method and apparatus to detect and filter out redundant cache line addresses in a prefetch input queue, and to adjust the detector window size dynamically according to the number of detector entries in the queue for the cache-to-memory controller bus. Detectors correspond to cache line addresses that may represent cache misses in various levels of cache memory.
