Abstract
Abstract A data processing system in which the interface for connecting a host controller to a burst multiplexor channel comprises two sections one to handle the transfer of data and the other to handle the transfer of command and status information. The interface also includes logic to monitor the division of any transfer into bursts and logic to arbitrate for the two sections for any given burst.
