摘要

Nowadays, multimedia applications are more and more used, and take a larger place in the workloads of modern computing systems. It appears that the classical 1D spatial locality arrangement in the cache is not adapted to the management of this data type, because its structures exhibit an intrinsic 2D locality.In this article, we study cache behavior and alternative strategies for multimedia, using a JPEG benchmark on an Itanium2#8482; cache system. We demonstrate, through systematic experiments, that performance can be very sensitive to data structure, revealing that cache organization has a major impact on performance. We then present the results of our experiments with suggestions to improve future media processing compiler design.
