PURPOSE:To enhance the reliability for the computer system by using the data output of one microprocessor for production of the data parity information of the microcomputer system. CONSTITUTION:Address output 13 of microprocessor 1 is connected to address output bus 8 to be supplied to RAM3, ROM4 and input/output port 5 each. Then the data output of microprocessor 2 is supplied to parity generator 70 to generate data parity output 71. Output 71 is supplied to RAM3 and also used for production of the data parity information of the microcomputer system. Thus the reliability can be enhanced for the computer system. |
