摘      要：This paper presents the design of a Coherence-Free Processor(CFP)that enables a scalable multiprocessor by eliminating cache coherence operations in both hardware and *** CFP uses a coherence-free cache(CFC)that can improve the cost-effectiveness and performance-effectiveness of the existing multiprocessors for commonly used *** CFC is feasible because not all program data that reside in a multiprocessor cache need to be accessed by other processors,and private caches at level 1(L1)and level 2(L2)facilitate this method of *** programs are specifically designed to protect their data from modification by other *** data that are modified but not shared with other tasks do not require a coherence *** processors reduces the multitasking queue,reducing elapsed *** execution replaces concurrent execution.
