Abstract
A resource request arbitration device is connected with each of a plurality of masters, and arbitrates transfer requests issued by the masters. The resource request arbitration device includes a plurality of counters each indicating a slack time of a transfer request issued by a master corresponding to the counter, and compares counter values stored in the counters by a tournament method, and specifies a master that has issued a transfer request having the highest priority. The resource request arbitration device grants access permission to the specified master to permit the specified master to use a slave.
