Circuit arrangement for use in controlling bridging between two computer communication buses ensures that data on one bus is available to the other bus for a selectable time

摘要

Device comprises a first circuit (1) that connects first (2) and second (3) communications buses and acts as a bus- master for the first bus. A second circuit (4) is connected to the first communications bus and has a first output (5) connected to the input (6) of the first bus-master circuit (1). In the second circuit a wait signal is generated that enable read or write access to the first bus over a chosen number of clock cycles. An independent claim is made for a method for controlling a connection between two communications buses.
