ABSTRACT:
A bridge for interconnecting a processor to a peripheral device by way of a PCI bus may have a read buffer. The bridge autonomously requests data from the peripheral device and places received data in the read buffer. The processor reads the data from the receive buffer. The bridge may have a write buffer. The bridge accumulates data in the write buffer until a triggering event occurs. Upon the occurrence of a triggering event the bridge sends the data in the receive buffer to the peripheral device in a burst.
