Cache memory control system that caches requested data and adjacently displayed data

摘要

A cache memory control system includes a cache memory to store a copy of a subset of data which is stored in the main memory and a cache controller to control data caching and data replacement for the cache memory. Upon a cache miss, the cache controller replaces data in the cache memory with the read requested data and a plurality of data which are adjacent to that read requested data on a display screen.
