Abstract
A multimedia video processor chip for a personal computer in employs a multi-port central cache memory to queue all the incoming data to be stored in a DRAM and all the outgoing data being retrieved from the DRAM. Such a cache memory is used in one of several modes in which the cache memory is partitioned by cache boundaries into different groups of storage areas. Each storage area of the cache is dedicated to storing data from a specific data source. The cache boundaries are chosen such that, for a given mode, the storage areas are optimized for worst case conditions for all data streams.
