<P>PROBLEM TO BE SOLVED: To provide a resource arbitration system, used by a plurality of devices (for example, processors etc.), that effectively allocates resources while suppressing influences on processing by the devices. <P>SOLUTION: The resource arbitration system includes a resource register 10 which is provided for each resource, and has a first identifier gid_rs indicative of a group that the resource belongs to, and a request register 11 which has a second identifier gid_rq indicative of a group to which the resource as a request object is allocated. For processing that a first device is schedule to execute, a first request having the second identifier gid_rq indicative of a group for reservation is made. When a first resource having accepted the first request is released, the first identifier gid_rs associated with the first resource is changed to the identifier indicative of the group for reservation. When the first identifier gid_rs associated with the first resource is changed to an identifier indicative of all groups for reservation, information on that is reported to the first device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
