PROBLEM TO BE SOLVED: To allow respective instruction process parts to process instructions synchronously even if an address error occurs. SOLUTION: If an error check part 10 detects an error in an address that an address reception part 6 has received through a bus line 18, an address processing part 15 discards the address and an error send-out part 7 outputs error detection signal to the bus line 18. If an error reception part 8 inputs error detection information outputted by other instruction process parts 2 and 3 although no error is found in the address, the address is discarded. Therefore, even when there are an instruction process part having detected an address error and an instruction process part having detected no address error for one address, either instruction process part discards the address. |
