Abstract
An apparatus includes an arbiter and a plurality of arithmetic processors, each including an arithmetic circuit and a measuring circuit. The arithmetic circuit executes an arithmetic process, and the measuring circuit measures a progress level indicating a progress of the arithmetic process executed by the arithmetic circuit. Upon receiving access requests to an external device from first arithmetic processors included in the plurality of arithmetic processors, the arbiter arbitrates the access requests, based on a result of comparing the progress levels measured by the measuring circuits of the first arithmetic processors.
