Abstract
A new integrated circuit for interfacing a standard IEEE 796 bus to a VSB-type buffer bus. This integrated circuit includes a DMA channel for high speed access of the IEEE 796 bus to the buffer bus, and a slave bus channel for high speed access of the buffer bus to the IEEE 796 bus. A third bus interface connects to a local processor to assist in arbitration and control during some types of data transfers.
