Solution of Cache coherence in SCMP
Suo Hong-jun · Journal of Xi'an University of Science and Technology · 2006
Single Chip Multiprocessors(SCMP) system is one of the most important microprocessor architectures today.Cache coherence must be maintained in SCMP,as well as in conventional multi-processors system.There are two classic cache coherence protocols: snooping based,which will lead to long latency with the increasing of nodes and directory based,which will lead to more conflict in directory access.A new cache coherence protocol,cache coherence based on dual-ring structure is proposed to solve these problems effectively.
