METHOD AND DATA PROCESSING SYSTEM FOR MICROPROCESSOR COMMUNICATION USING PROCESSOR INTERCONNECTED IN 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: The identical processing communication information useful in pipelined multiprocessing or parallel multiprocessing is stored in each processor communication register (PCR). Each processor possesses an exclusive right to store to a sector within each PCR and has continuous access to read PCR contents of itself. Each processor updates its exclusive sector within all of the PCRs using communication over a specialized bus, makes all other processors to be able to quickly see the change within the PCR data and bypasses a cache subsystem.
