Scheduling method of multiple core system and multiple core system and scheduling program null plural processor

摘要

Profile information about the access to peripheral devices for each task assigned to the processor core (26) is prepared in advance. To monitor the access request to each of the peripheral devices from the task of running on each processor core based on profile information (26) and (27) monitoring unit. Running task processor core # 0_ (21) is requesting access peripherals A (24) when the task of running the processor core # 1_ (22) is accessing (25) peripheral B Then, bus contention takes place, the monitoring unit (27) to prohibit the access request of the running task processor core # 0_ (21). (28) to switch to another task that does not cause a bus conflict on the basis of profile information (26) the task of running the processor core # 0_ (21) scheduler.
