Abstract
The present invention discloses a bi-directional bus system including one or more junction circuits and a plurality of logic blocks wherein each logic block includes circuitry for transmitting and receiving data and a driver circuit for selectively driving an idle state or data signals as output signals. A bi-directional bus segment for conducting data signals thereon couples a logic block or a junction circuit to another junction circuit. The output signal to each bi-directional bus segment coupled to a junction circuit is a function of the input signals from all the other bi-directional bus segments coupled to the junction circuit and is controlled by one input signal not being driven into the idle state when all the other input signals are driven into the idle state. The bi-directional bus segment coupled to each logic block directly provides input signals to the logic block.
