| 摘要 |
In accordance with the invention, a multi-processing unit system (10) including a plurality of processing units (14-38) in direct communication via a communication bus (12) is presented. The system includes a communication bus arbiter (40) having a communication packet multiplexer. Each of the processing units include a communication bus interface comprising a transmitter interface and a receiver interface. Each of the transmitter interfaces are connected to the communication packet multiplexer of the communication bus arbiter via separate 32-bit interfaces. Each of the receiver interfaces is connected to the communication packet multiplexer of the communication bus arbiter via a single 32-bit bus. The system may further comprise a first control signal connection means for communicating control signals between the transmitter interface and the communication bus arbiter and a second control signal connection means for communicating control signal between the receiver interface and the communication bus arbiter.
