Abstract
An exclusion controller which allows an information processing unit to acquire a contended resource to the exclusion of the other information processing units includes a plurality of non-prioritized information processing units mutually exclusively acquiring a non-prioritized exclusion right, which indicates a candidate for acquiring the contended resource, by a first process. The exclusion controller further includes a prioritized information processing unit acquiring the contended resource by a second process, which requires a shorter processing time than the first process, to the exclusion of the non-prioritized information processing unit having acquired the non-prioritized exclusion right.
