FAIL-FIRST, FAIL-FUNCTIONAL AND FAULT-TOLERANT MULTIPROCESSOR SYSTEM |
摘要 |
PROBLEM TO BE SOLVED: To reduce the processing system cost by providing an error inspecting function and masking a fault through hardware in duplex mode operation. SOLUTION: A data processing system 10 is equipped with two subprocessor systems 10A and 10B which have the same constitution and functions. This pair of the subprocessor systems 10A and 10B include a processor device (CPU) 12, a router 14, and an I/O packet interface 16 having a relative I/O device 17. Each of the pair of the CPUs 12 receive an error signal and returns an echo-back error signal to a couple of data communication elements. Then it is determined whether or not each CPU 12 continues to operate according to the error signal and echo-back error signal; and then one of the CPUs 12 continues to operate and the other CPU 12 finishes operating. |
