Abstract

A method and apparatus for broadcasting data to multiple target devices during a single bus transaction. Each of a plurality of potential target devices detect the beginning of a primary bus transaction and retrieve transaction command and target device identification information from a multicast bus. The transaction command information and target device identification information are decoded. A determination is made by each device as to whether the decoded target device identification information matches the identity of the device and furthermore whether the decoded transaction command is a read command. If the target device identification information matches the identity of the device and the command is a read, the device writes data present on the primary device into the device.
