Systems and methods for sharing a serial communication port between a plurality of communication channels

摘要

An apparatus for sharing a serial communication port between a plurality of communication channels is described. The apparatus comprises a transceiver that manages communications over the serial communication port. The apparatus also includes a multiplexer coupled to the transceiver, wherein the multiplexer multiplexes the plurality of communication channels. The apparatus also includes identification information circuitry coupled to the multiplexer, wherein the identification information circuitry adds identification information to data from the plurality of communication channels that enables the plurality of communication channels to share the serial communication port. The serial communications port and the multiplexer permit communication between integrated circuits that meet at least one latency metric for the plurality of communication channels when the plurality of communication channels are active.

1. An apparatus for sharing a serial communication port between a plurality of communication channels, comprising:
a transceiver that manages communications over the serial communication port; a multiplexer coupled to the transceiver, wherein the multiplexer multiplexes the plurality of communication channels; and identification information circuitry coupled to the multiplexer, wherein the identification information circuitry adds identification information to data from the plurality of communication channels that enables the plurality of communication channels to share the serial communication port; wherein the serial communication port and the multiplexer permit bi-directional communication between a modem in the apparatus and an analog chip in the apparatus coupled together by a high-speed clock line serial link that meet at least one latency metric for the plurality of communication channels when each of the plurality of communication channels is active.
