  • Patent number: 11949629
    Abstract: A signaling link retimer injects flow-rate compensation transmissions into a synthesized symbol stream in coordination with flow-rate compensation transmissions detected within a received symbol stream, enabling the retimer to switch seamlessly between forwarding the received symbol stream and outputting the synthesized symbol stream.

  • Patent number: 11941436
    Abstract: An integrated-circuit retimer selectively logs information corresponding to mission-mode data, received and transmitted via counterpart high-bandwidth data interfaces, in real-time and accordance with contents of a logging control storage written by an external component during retimer run time.

  • Patent number: 11853115
    Abstract: A low-latency signaling link retimer generates an output signal transmission synchronously with respect to a core clock signal alternately selected from two or more plesiochronous or mesochronous clock sources with switchover between or among the core-clock sources executed without shrinking, extending or otherwise disrupting the edge-to-edge core clock period or clock duty cycle.

  • Patent number: 11722152
    Abstract: A memory control component encodes over-capacity data into an error correction code generated for and stored in association with an application data block, inferentially recovering the over-capacity data during application data block read-back by comparing error syndromes generated in detection/correction operations for respective combinations of each possible value of the over-capacity data and the read-back application data block.

  • Patent number: 11424905
    Abstract: First and second clock signals are generated based on signal transitions within first and second streams of symbols, respectively, received within an integrated circuit component, the first and second clock signals having a time-varying phase offset with respect to one another. A first control circuit, operating in a first timing domain established by the first clock signal, generates first control information based on the first stream of symbols and forwards the first control information, via a domain crossing circuit that bridges the time-varying phase offset, to a second control circuit operating in a second timing domain. The second control circuit generates a third stream of symbols based on the first control information and on the second stream of symbols, and a transmit circuit outputs the third stream of symbols from the integrated circuit component synchronously with respect to the second clock signal.

  • Patent number: 11327913
    Abstract: Groups of signal conductors within a configurable communication system are managed by respective, dedicated media controllers implement a configurable number of independent communication channels through coordinated action so that signal conductors need not be multiplexed to/from multiple controllers and no media controllers or input/output driver circuits therein need be disabled in any configuration.
