| 摘要 |
A preferred embodiment includes a distributed network of a plurality of dynamically configurable bi-directional input/output (I/O) cells, each including a forward datapath having a first receiver, for receiving a first input signal from downstream driver on a first port of a signal line, coupled to a first driver for sending a first output signal to a first upstream receiver on a second port of the signal line; and a reverse datapath having a second receiver, for receiving a second input signal from a second downstream driver on the second port of the signal line, coupled to a second driver for sending a second output signal to a second upstream receiver on the first port of the signal line; wherein the first input signal and the second output signal are transmitted concurrently on the first port of the signal line.
