Abstract
An information processing device collects status information for a large number of input and output devices simultaneously. A bridge circuit having a multicast function connects an information processing unit with a plurality of input and output devices. By setting the multicast to the bridge circuit, the bridge circuit forwards a packet which instructs a copy of the status information to the plurality of input and output devices by multicast, and a DMA circuit in the plurality of input and output devices simultaneously starts DMA transfer of the status information to the processing unit.
