MULTI-PROCESSOR SYSTEM HAVING INDIVIDUAL AREA IN SHARED MEMORY

摘要

PROBLEM TO BE SOLVED: To prevent the deterioration of processing capabilities, and to efficiently and economically structure a highly reliable and stable system in a multi- processor system in which the individual memory of each processor module is assigned as an individual area in a shared memory.;SOLUTION: This multi-processor system is provided with plural processor modules 10-0-10-n including at least one primary processor module 10-n and a shared memory 15 to be commonly used by each processor module. The shared memory 15 is provided with individual areas 17-0-17-n-1 assigned to each processor module, and a shared memory mapping table 16-1 and an address converting part 16-2 for converting memory access from each processor module into access to each individual area in the shared memory 15. Also, this multi- processor system is provided with a switching control part 18-1 for switching the assignment of the individual areas of the processor module in which any failure is generated and the primary processor module by monitoring each processor module.;COPYRIGHT: (C)2001,JPO
