  • Patent number: 10164809
    Abstract: In a detection circuit, inputs correspond to received indications of vector signaling code words received by a first integrated circuit from a second integrated circuit. With four inputs, the circuit compares a first pair to obtain a first difference result and compares a second pair, disjoint from the first pair, to obtain a second difference result. The first and second difference results are then summed to form an output function. A system might use a plurality of such detection circuits to arrive at an input word. The circuit can include amplification, equalization, and input selection with efficient code word detection. The vector signaling code can be a Hadamard matrix code encoding for three input bits. The circuit might also have frequency-dependent gain, a selection function that directs one of the summation function result or the first difference result to the output function, variable gain, and/or a slicer.

  • Publication number: 20180302181
    Abstract: Properties and the construction method of Orthogonal Differential Vector Signaling Codes are disclosed which are tolerant of order-reversal, as may occur when physical routing of communications channel wires causes the bus signal order to be reversed. Operation using the described codes with such bus-reversed signals can avoid complete logical or physical re-ordering of received signals or other significant duplication of receiver resources.

  • Patent number: 10091035
    Abstract: 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.

  • Publication number: 20180176045
    Abstract: Vector signaling codes are synergistically combined with multi-level signaling, the increased alphabet size provided by the multi-level signaling enabling a larger codeword space for a given number of symbols, at the cost of reduced receiver detection margin for each of the multiple signal levels. Vector signaling code construction methods are disclosed in which code construction and selection of multi-level signal levels are coordinated with the design of an associated receive comparator network, wherein modified signal levels encoded and emitted by the transmitter result in increased detection margin at the receive comparators.
