摘要： The present invention discloses a method and apparatus for addressing the issue of clock skew in a data signal while making efficient use of space on an integrated chip (IC) by utilizing a physical delay line controlled by a state machine in conjunction with pre-requisite chip architecture. The pre-requisite chip architecture samples the incoming data signal in response to a clocking signal input from the physical delay line; the physical delay line responds to commands from the state machine to increment the delay of the physical delay line to produce samples which describe the incoming data signal and delineate its data valid window.

摘要： An apparatus for determining the amount of skew to be injected for system skew compensation in a high-speed data communications system including a plurality of lanes with a data bus per lane. Such skew compensation is necessary due to inherent system skew. By iterating through the possible intervals within the maximum expected skew search space, the correct combination of search space intervals for all lanes can be determined to provide alignment and thus compliancy with relevant standards, such as the SFI-5 and SxI-5 standards, in terms of data skew specifications.

摘要： An apparatus for determining the amount of skew injected into a high-speed data communications system, including a plurality of lanes having a data bus per lane, relative to a reference lane, for system skew compensation. By knowing the relative amount of skew that each lane requires for alignment, an appropriate amount of skew is then injected on each lane to provide alignment and thus compliancy with the SFI-5 and SxI-5 standards, in terms of data skew specifications. The relative skew amounts for each transmitting lane are determined using dual loopback methods.

摘要： This algorithm and apparatus provides the ability to determine the amount of skew that should be injected into a high-speed data communications system consisting of a plurality of lanes comprising a data bus on a per lane basis, relative to a reference lane, for the purpose of compensating for inherent system skew. By knowing the relative amount of skew that each lane requires for alignment, an appropriate amount of skew can then be injected on each lane to provide alignment and thus compliancy with relevant standards, such as the Sxl-5 standard, in terms of data skew specifications. These relative skew amounts for each transmitting lane are determined using a methodology involving internal loopback and characteristics from the connected communications element to the chip receive path.

摘要： The present disclosure relates to a directional pixel for a high-angular resolution, wide field of view, multiple view display. The design teaches a directional pixel comprising a substrate, one or more pixel driving circuits, one or more nano- or micro-scale subpixels, and one or more directional optical guiding surfaces, wherein each of said one or more subpixels is comprised of a light emitting device emitting a light beam and an optical microcavity housing said light emitting device. The optical microcavity is comprised of a plurality of reflective surfaces to specifically manipulate and tune said light beam, wherein one or more of said reflective surfaces is a light propagating reflective surface which propagates said light beam out of said microcavity, and said light propagating reflective surface is connected to said one or more directional optical guiding surfaces to direct said light beam at a specific angle. A high-angular resolution, multiple-view light-field display is created by deploying a plurality of directional pixels into a directional pixel array system.

摘要： A method of performing forward error correction with configurable latency, where a configurable latency algorithm evaluates a target Bit Error Rate (BER) against an actual BER and adjusts the size of a configurable buffer such that the target BER may be achieved when utilizing the smallest buffer size possible. When errors are corrected without the utilization of each of the configurable buffer locations, the algorithm reduces the size of the buffer by y buffer locations; the algorithm may continue to successively reduce the size of said buffer until the minimum number of buffer locations are utilized to achieve the target BER. If the buffer locations have been reduced such that the buffer size is too small and the target BER cannot be achieved, the algorithm may increase the size of the buffer until the minimum number of buffer locations are utilized to achieve the target BER.
