摘要：
A device control apparatus includes a request accepting unit which accepts a device control request, the device control request containing an instruction code indicating a specified instruction and a device identifier indicating a specified device. A competition control unit includes a set of competition definition tables for respective devices and respective device-control instructions, reads out one of the competition definition tables by the device control request, and recognizes competition states between in-process instructions to competition devices and the specified instruction to the specified device by using the read-out competition definition table. A parallel execution control unit performs execution of one or a plurality of the specified instruction and the in-process instructions in accordance with the competition states when a sum of a first weight for the specified instruction and a second weight for the in-process instructions is less than a maximum weight.
