VFCC: A verification framework of cache coherence using parallel simulation

A cache coherence protocol is a vital component of a multiprocessor to maintain the data consistency. In this paper, we proposed VFCC, which is a simulation framework to validate a cache-coherence protocol implementation of a commercial 64-bit superscalar multiprocessor. It exploits multiple-level parallelism to accelerate validation without overheads among threads. Our experimental results demonstrate VFCC has a 5.0?? speedup than a traditional simulator on a conventional 16-core host machine. ? 2013 IEEE.EI
