transferring data to a destination agent. Each of the plurality of ports is further
customized with a crossbar control data (64, 66, 72, 74, 80, 82, 88, 90) for specifying
crossbar control information, and for transferring data from an input port to an output
port having different port configurations. The crossbar control data also includes control
information for formatting bit length of data from an input port to be transmitted to an
output port having less width than the input port.
Claim 1 is representative of the claimed invention and is reproduced as follows:
1. A crossbar for providing connections between a plurality of ports
and a plurality of system agents via a processing system comprising:
a plurality of ports, each port capable of being an input port customized
for receiving data from a source agent and an output port customized for
transferring data to a destination agent; and,
crossbar control data for specifying crossbar control information for
transferring data from an input port to an output port having different port
configurations, said crossbar control data containing control information for
formatting bit length of data from an input port to be transmitted to an output
port having less width than the input port.
