Abstract
In an information processing system having a bus bridge connected between a plurality of buses for data transfer therebetween, the bus bridge is provided with a RAS data acquisition bus operating independently from the plurality of buses and a RAS data acquisition circuit for acquiring RAS data, the RAS data acquisition circuit acquires RAS data in the bus bridge or RAS data of a processor or an I/O device on a bus connected to the bus bridge, in response to a command supplied from an external circuit via the RAS data acquisition bus. The RAS data acquisition circuit sends the acquired RAS data to the external circuit via the RAS data acquisition bus.
