Abstract: PROBLEM TO BE SOLVED: To provide a system serialization method by the early release of individual processors by generating a system standstill request and the request of the updating of a global resource by the processor, responding to the request and buffering the request in the processor during the processing. SOLUTION: Plural CPUs 210 and 211 in a system respectively execute an instruction from a simple instruction set and the instruction from a complicated instruction set in the execution controller 243 of hardware control. The respective CPUs 210 and 211 generate the system standstill request and the request of the updating of the global resource and respond to the request. Then, during the processing, the system standstill request and the request of the updating of the global resource are buffered in one or more of the CPUs 210 and 211. A system operation controller provided with a system serialization controller 220 or the like instructs the updating the global resource.

Abstract: PROBLEM TO BE SOLVED: To obtain a system which performs system serialization by early releasing of a processor by buffering a system standstill request and a request for updating on the processor. SOLUTION: Plural processors are included in this system and respective processors generates system standstill requests and requests to update global resources and responds to the requests. The system standstill request and the request for updating are buffered by one or plural processors. Then a system operation controller including a storage device controller SC 212 and a system serializing a controller 220 indicates the updating of the global resources. The global resources include an address conversion table entry and a protection key.
