METHOD AND DATA PROCESSING SYSTEM FOR MICROPROCESSOR COMMUNICATION IN CLUSTER BASED MULTIPROCESSOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an improved data processing system architecture reducing waiting time of communication between physically separating processors, reducing bus bandwidth consumption, and releasing the bus bandwidth for a general data transfer between the processor and a hierarchical memory system.

SOLUTION: Information useful in pipelined multiprocessing or parallel multiprocessing is stored in each processor communication register (PCR). Each processor possesses an exclusive right to store a sector within each PCR and has continuous access to read the contents. Each processor cluster updates its exclusive sector within the PCRs, makes all other processors within the cluster network to be able to quickly see the change within the PCR data and bypasses a cache subsystem.
