摘要： Disclosed herein are techniques to provide forward error correction for a high-speed interconnect symbol stream, such as, DisplayPort. The symbol stream may be split into FEC blocks and parity bits generated for each of the FEC blocks. The parity bits may be interleaved, encoded, and transmitted over an interconnect along with the symbol stream to provide forward error correction for the symbol stream.

摘要： A device system and method is provided for early termination of a decoding process performed at a receiving user device. A user-specific message may be received, from a communication channel shared by multiple user devices. The user-specific message may include an error correction codeword generated by shifting an original codeword by an offset codeword uniquely associated with a target user device. The error correction codeword may be shifted based on an offset codeword uniquely associated with the receiving user device. The received message may begin to be decoded. If the receiving device is the target device, the offsets respectively associated therewith are equal and cancel, and the original message is decoded to completion. If, however, the receiving device is not the target device, the offsets respectively associated therewith are not equal and combine to form an above threshold decoding error and decoding is terminated before completion.

摘要： Conventional link error correction techniques in memory subsystems include either widening the I/O width or increasing the burst length. However, both techniques have drawbacks. In one or more aspects, it is proposed to incorporate link error correction in both the host and the memory devices to address the drawbacks associated with the conventional techniques. The proposed memory subsystem is advantageous in that the interface architecture of conventional memory systems can be maintained. Also, the link error correction is capability is provided with the proposed memory subsystem without increasing the I/O width and without increasing the burst length.

摘要： Systems and methods are described for transmitting data over physical channels to provide a high bandwidth, low latency interface between a transmitting device and a receiving device operating at high speed with low power utilization. Communication is performed using group signaling over sets of four wires using a vector signaling code, where each wire of a set carries a low-swing signal that may take on one of four signal values. Topologies and designs of wire sets are disclosed with preferred characteristics for group signaling communications.
