Samsung patents circuit that adjusts data links to prevent errors
Samsung has filed a patent for a communication interface circuit that manages how data is sent across multiple wire connections. The system uses a control code to change how data is encoded based on how the wires are connected, which helps maintain a stable signal during transmission.
In the filing’s own words
A communication interface circuit includes a protocol layer circuit that generates packet data based on input data, and a physical layer circuit that encodes the packet data to output a transmission state, and drives a data lane including a plurality of three-phase wire links based on the transmission state, wherein the physical layer circuit may include an encoder that calculates the transmission state based on a preceding state output from the encoder in a previous unit interval, a symbol mapped to the packet data, and a control code, and wherein the control code instructs an encoding change based on a coupling relationship of the plurality of three-phase wire links. The communication interface circuit stably transmits data.
What exactly they claim (claim 1)
1. A communication interface circuit comprising: a protocol layer circuit configured to generate packet data based on input data; and a physical layer circuit configured to encode the packet data to output a transmission state, and drive a data lane including a plurality of three-phase wire links based on the transmission state, wherein the physical layer circuit includes an encoder configured to calculate the transmission state based on a symbol mapped to the packet data, and a control code, and wherein the control code is configured to instruct an encoding change based on a coupling relationship of the plurality of three-phase wire links.
