摘要:
A processor communication register (PCR) contained in each processor within a multiprocessor cluster network provides enhanced processor communication. Each PCR stores identical processor communication information that is useful in pipelined or parallel multi-processing. Each processor has exclusive rights to store to a sector within each PCR within the cluster network and has continuous access to read the contents of its own PCR. Each processor updates its exclusive sector within all of the PCRs via a private protocol or dedicated wireless network, instantly allowing all of the other processors within the cluster network to see the change within the PCR data, and bypassing the cache subsystem. Efficiency is enhanced within the processor cluster network by providing processor communications to be immediately networked and transferred into all processors without momentarily restricting access to the information or forcing all the processors to be continually contending for the same cache line, and thereby overwhelming the interconnect and memory system with an endless stream of load, store and invalidate commands.
