More Information
Summary:A method of providing an interconnection between one or more peripheral devices and a system bus of a computer system selectively establishes and removes a connection from a primary peripheral bus to a secondary peripheral buses, and determines a target from among the one or more peripheral devices when a bus bridge is a master of the primary peripheral bus, using an address decoder. Access to and from the primary peripheral bus is controlled using an arbiter to select a master for the primary peripheral bus from among the one or more peripheral devices, to allow both (i) selective establishing and removing of a connection from the primary peripheral bus to one of the secondary peripheral buses in response to the selection of the master, and (ii) isolating of the master prior to establishing the connection to the secondary peripheral bus.
