<p>Provided is a control device that guarantees transmission performance while minimizing the operating frequency of a bus. This control device is used for controlling transmission timing of access requests that are received from initiators via distributed buses in a system in which the initiators and targets are connected together by means of the buses. The control device stores information about an intermittent cycle which allows an inter-packet interference to be minimized, said intermittent cycle information being generated from system configuration information and flow configuration information about per-unit-flow specifications needed for the respective initiators to access the targets, and intermittent information which includes information about minimum bus operating frequencies at which real-time performances of the respective initiators can be guaranteed. The control device is provided with: a clock generation unit that generates clocks according to the bus operating frequency information; a communication unit; and a transmission interval determination unit that determines times to issue transmission permissions in response to the transmission requests on the basis of the intermittent cycle, the detected times of the transmission requests, and the last transmission times.</p> |
