FAIL-FIRST, FAIL-FUNCTIONAL AND FAULT-TOLERANT MULTIPROCESSOR SYSTEM |
摘要 |
PROBLEM TO BE SOLVED: To add no delay to access by providing an error inspecting function and performing error inspection by an interface so that no influence is exerted on performance. SOLUTION: A data processing system 10 is equipped with two subprocessor systems 10A and 10B which have substantially the same structure and functions. Each of the subprocessor systems 10A and 10B includes a central processing unit(CPU) 12, a router 14, and plural I/O packet interfaces 16 coupled with many I/O devices 17. The pair of CPUs 12 is each equipped with an interface device. Those interface devices receive specific parts of N-bit data words from the other interface devices to which an error signal detected by miscomparison should be asserted and compare them with specific parts of N-bit data words received from the corresponding CPUs 12. |
