A Simple Distributed Directory-based Protocol for Simics
Cao Hong-xi · Computer and Modernization · 2011
As a full-system simulation technology allowing one to completely simulate the functionality of computer systems with different memory hierarchy configurations and different number of processors,Vitutech Simics has an in-order 'flat' cache model which only provides with a simple snooping cache coherence protocol support for a simple MESI protocol between caches with a unified shared memory.This limits the number of processors that can be scalable to simulate for the logical bus contention.This paper presents a simple distributed directory-based cache coherence protocol that will solve scalability problem of Simics.
