FAIL-FIRST, FAIL-FUNCTIONAL AND FAULT TOLERANT MULTIPROCESSOR SYSTEM

Title:

FAIL-FIRST, FAIL-FUNCTIONAL AND FAULT TOLERANT MULTIPROCESSOR SYSTEM

Document Type and Number:

Japanese Patent JPH09134332

Kind Code:

A

Abstract:

To provide a multiprocessor system which can attain the fail-first, fail-functional and fault tolerant actions.

This multiprocessor system includes the sub-processor systems 10A and 10B which have the substantially same constitution. The CPU 12A and 12B of systems 10A and 10B can communicate with the I/O devices 171 to 17n or the CPU of the multiprocessor system via the routing devices 14A and 14B. The communication is performed between the I/O devices and the multiplexed CPUs by means of the messages which are turned into a packet. These CPUs and I/O devices are written into or read out of the CPU of the multiprocessor system. The protection of the CPU memory is maintained by every CPU that has a priority check function of the read/write operations which are carried out against the CPU memory.
