Apparatus, method and system for asymmetric, full-duplex communication

摘要

Techniques and methods for performing asymmetric, full-duplex communication via a signal line. In an embodiment, a transceiver includes transmit circuitry to transmit a first signal via a node coupled to a signal line, where the first signal is transmitted concurrently with the transceiver receiving a second signal via the node at a substantially different data rate than that of the first signal. In another embodiment, signal processing circuitry of the transceiver detects a composite signal at the node, the composite signal including a combination of the first signal and the second signal. Based on the combination of the first signal and the second signal, the signal processing circuitry generates a processed signal, including the signal processing circuitry reducing a contribution by the first signal. The processed signal is provided to receiver circuitry of the transceiver.

1. A first device comprising:
a first transceiver configured to perform, with a second device coupled to the first device, asymmetric full-duplex communication of a first signal and a second signal, the first transceiver including:
first transmitter circuitry configured to transmit the first signal from the first device via a first node while the second device transmits the second signal to the first node,wherein a superimposed signal of the first signal and the second signal is formed at the first node:signal processing circuitry coupled to the first node, the signal processing circuitry configured to generate a third signal from the superimposed signal, including the signal processing circuitry to reduce a contribution by the first signal; andfirst receiver circuitry coupled to receive the third signal from the signal processing circuitry, wherein one of the first signal and the second signal includes a stable portion comprised of two or more consecutive placeholder bits which each have the same logic level, wherein an exchange of the stable portion is concurrent with a transition time of the other of the first signal and the second signal.
