Open publisher page 0 citations

Abstract

This paper introduces some typical directory organization schemes and analyzes their advantages and disadvantages. By full using advantages of full-map directory and limited directory, an improved directory-based Cache-coherent protocol is presented and discussed here, which adds a Cache level upon the memory level. It limites the space cost increase, while the system performance and system scalability have a remarkable enhancement.
