Flux caches: what are they and are they useful?

Abstract

In this paper, we introduce the concept of flux caches envisioned to improve processor performance by dynamically changing the cache organization and implementation. Contrary to the traditional approaches, processors designed with flux caches instead of assuming a hardwired cache organization change their cache ¿design¿ on program demand. Consequently program (data and instruction) dynamic behavior determines the cache hardware design. Experimental results to confirm the flux caches potential are also presented.
