PROBLEM TO BE SOLVED: To prevent a deterioration in performance in a system controller adopting a system for transmitting a response packet prior to a request packet.SOLUTION: A system controller 2 connected to a plurality of arithmetic processing units 1 has: a request holding part 8 for storing a request from a first arithmetic processing unit 1 among the plurality of arithmetic processing units 1; a response holding part 11 for storing a response to a second arithmetic processing unit 1 among the plurality of arithmetic processing units 1 corresponding to the request from the first arithmetic processing unit 1; and an arbitration part 12 for outputting a response prior to a request when the response holding part 11 has already held the response in the case that the request is stored in the request holding part 8, and outputting the request prior to the response when the response has not been held in the response holding part 11 yet in the case that the request is stored in the request holding part 8. |
