Abstract
PURPOSE: To proceed the normal data transfer without report of failure to the processor, when an error is detected to the output of one register, by making duplex buffer registers for input data storage and comparing the output of both the registers for check.
CONSTITUTION: A transfer data is simultaneously stored in the 1nst and 2nd registers 6, 7 in a normal timing T1, and stored data is given to incorrect data detection circuits 11, 12, comparison circuit 13 and a selection circuit 14. Further, the output of registers 6, 7 is compared by bits at the circuit 13, and the result is set to the 3rd register 38. Further, incorrect data detection signals 16, 17 are fed to AND gates 19W21 after they are inspected at the circuits 11 and 12, and when incorrectness is detected, a failure report signal 49 is output via an interface control circuit 47 to a data processor 200. Further, the output of a register 38 is fed to the circuit 47, the selection circuit output signal 33 selected at the circuit 14 is fed to the circuit 47, enabling to transfer the normal data when an error in one register 6 or 7 is detected.
