  • Patent number: 11561920
    Abstract: A device includes a first interface to receive a signal from a first communication link, wherein the receive signal includes out-of-band (OOB) information. A detector coupled to the first interface detects the OOB information. An encoder coupled to the detector encodes the OOB information into one or more symbols (e.g., control characters). A second interface is coupled to the encoder and a second communication link (e.g., a serial transport path). The second interface transmits the symbols on the second communication link. The device also includes mechanisms for preventing false presence detection of terminating devices.

  • Publication number: 20120215952
    Abstract: Video data is transmitted from a video source to a video sink via a fixed rate serial link with a substantially constant unit interval for transmission of each symbol of the encoded data. The unit interval of the serial link is maintained substantially constant, and does not vary regardless of the display parameters of the video data. The video data is encoded into a plurality of video data streams, with each data stream including a plurality of fields. The fields include at least a clock offset field and video payload data fields. The clock offset field includes phase information indicative of the phase of the display clock offset with respect to a time reference, indicated in terms of the number of unit intervals offset from the time reference. The video sink recovers the display clock based on the display clock offset information, and thus no display clock itself is transmitted from the video source to the video sink.

  • Patent number: 6061815
    Abstract: A algorithmic pattern generator (APG) in a memory tester having a programmable first ALU generating an first value on a first output data path; a programmable Z ALU generating a Z value on an Z output data path; and a programmable second ALU having terminals to receive the Z value from the Z ALU and a circuit to insert bits of the received Z value into low order bits of a second value before outputting the second value on a second output data path. In embodiments, the first value and the second value are generated to define a location in an array of memory cells of a memory under test; and the second value contains low order bits corresponding to address bits that are incremented internally by the memory under test in a burst mode of operation.
