Abstract
Provided is a hierarchical arbitration device wherein an arbitration device at each level of the hierarchy selects a resource use request having the highest priority and a resource use request having the second highest priority, outputting these two resource use requests to the arbitration device that is one level higher. After outputting the memory use request having the highest priority to a resource control unit as the top priority resource use request, when the arbitration device at the highest level of the hierarchy receives a signal from the memory control unit indicating receipt of the resource use request, the arbitration device then selects the resource use request having the second highest priority and outputs this resource request as the next top priority resource use request.
