Abstract:
An intelligent tile-based prefetching solution executed by a compression address aperture services linearly addressed data requests from a processor to memory stored in a memory component having a tile-based address structure. The aperture monitors tile reads and seeks to match the tile read pattern to a predefined pattern. If a match is determined, the aperture executes a prefetching algorithm uniquely and optimally associated with the predefined tile read pattern. In this way, tile overfetch is mitigated while the latency on first line data reads is reduced.
