ABSTRACT:
A plurality of units (processing units) connected to a crossbar are divided into a plurality of groups and one is selected from requests selected for each group according to priority among the groups that changes at prescribed time intervals. Thus, the number of times per unit time requests issued from units belonging to a group whose priority is improved at the prescribed time intervals can be maintained over a certain value regardless of a request state.
