Abstract
Bandwidth information including a plurality of slots each having highest priority order information for arbitrating access conflict, and priority master information for specifying, as a priority master, one or more of a plurality of masters whose latency in accessing a memory serving as a shared resource is desired to be reduced are included as arbitration information. When an arbitration section arbitrates access conflict while switching the slots in the bandwidth information at each of predetermined arbitration timings, if there is an access request from the priority master specified in the priority master information, the arbitration section changes the sequence of the slots in the bandwidth information so as to allow the priority master to access the memory with priority.
