Customised ports in a crossbar and method for transmitting data between customised ports and system agents

摘要

A crossbar (50) and method (180) for providing connections between a plurality of ports and a plurality of system agents via a processing system, which includes a plurality of ports (52, 54, 56, 58), each port being capable of being an input port (60, 68, 76, 84) customized for receiving data from a source agent and an output port (62, 70, 78, 86) customized for transferring data to a destination agent, and crossbar control data (66, 74, 82, 90) for specifying crossbar control information for transferring data from an input port to an output port having different port configurations.
