Abstract: An instruction control circuit decodes an instruction and issues a request. A cache control pipeline determines whether or not the requests output from local request ports, an external request port, and an order port are processable. When the request is not processable, then the cache control pipeline performs end processing that includes aborting the request and requesting other request to another request port among the plurality of request ports except the request port which output the request which is not processable for re-output. When a request is processable, then the cache control pipeline performs pipeline processing that includes the requested processing according to the request. A processing sequence adjusting circuit makes the cache control pipeline perform the end processing with respect to a subsequent request which is output after a possible request from the request port that has already output the possible request with respect to which the control pipeline performed the requested processing.
