<p>A large number of requests can be stored irrespective of the buffer capacity of a response side, and the processing efficiency of a CPU core can be improved. A cache (102) receives a request from an instruction execution unit (101), searches for necessary data, outputs the data to the instruction execution unit (101) if there is a cache hit, and instructs a request storage unit (103) to request a move-in of the data if a cache miss occurs. The request storage unit (103) stores therein the request corresponding to the instruction of the cache (102) while the requested process is being executed. A REQID assignment unit (104) reads the request stored in the request storage unit (103), selects an unused REQID from a REQID table (105), and assigns the unused REQID to the read request. The REQID is an identification number of the request based on the number of requests set as the maximum number that can be received at a simultaneous time by a system controller (200) of the response side.</p> |
