Abstract
PURPOSE: To increase the reliability of unit and the operation rate, by comparing the result of input clock count of the main counter circuit and auxiliary counter circuit and displaying failure with the output of the logical product circuit if parity error signal is produced from the both circuits.
CONSTITUTION: The main counter circuit 1 counts the inputs data based on the clock to detect the parity error of the result of the counter with the error detection circuit 3. On the other hand, the auxiliary counter detection circuit 2 had the same constitution as the circuit 1, the input data is counted at the clock, and the parity error of the result of count is detected with the error detection circuit 4. The comparison circuit 7 compares the result of count of the circuits 1 and 2, and if the parity error detection signal is produced from the both of the circuits 3 and 4, the logical product circuit 9 produces the output, and when the output of the circuit 9 is given with coincidence of the result of comparison of the circuit 7, the reliability and operation rate of the unit can be increased by displaying failure.
