A Study of Hardware Prefetch Techniques for Mpeg-Play This talk will be a continuation of work presented last quarter in which initial results were presented for the data cache behavior of the multimedia benchmark, mpeg_play. This quarter I will present results comparing performance of various specialized prefetching caches, including Fu, Patel, and Janssens' Stride Cache, Jouppi's Stream Cache, and a new hybrid cache configuration that combines useful features from each.
