More Information
Summary:An arbitration circuit includes a use frequency setting block that sets a setting value for limiting a bus use frequency for each of a plurality of masters. A use request management section holds the bus use request from each of the plurality of masters and selects a use request that has not been granted from among the held use requests. A use frequency limitation block limits the use request selected by the use request management section such that the bus use frequency of each of the plurality of masters will not exceed its setting value. A use request grant block grants a use request of any one of the plurality of masters from among use requests not limited by the use frequency limitation block received from the plurality of masters.
