Abstract

Today, low-cost, high-performance processors are required in many products such as portable terminals and network appliances, and the demand for on-chip multiprocessors is increasing. The authors have proposed a semi-shared pseudo set associative cache for on-chip multiprocessors, or pSAS, which offers both high speed of the snoop cache and on-chip cache memory efficiency of the shared cache. Although pSAS can directly access other caches with some delay, its performance deteriorates if it continues to access other caches. In this article, we propose the pSAS/c cache that solves this problem by copying frequently accessed data into self-cache and accessing it as fast as the snoop cache.
