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.

Abstract: A packet processing system having each of a plurality of hierarchical clients and a packet memory arbiter serially communicatively coupled together via a plurality of primary interfaces thereby forming a unidirectional client chain. This chain is then able to be utilized by all of the hierarchical clients to write the packet data to or read the packet data from the packet memory.

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.

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.

Abstract: A multi-dimensional mesh architecture is proposed to support transmitting data packets from one source to a plurality of destinations in multicasting or broadcasting modes. Each data packet to be transmitted to the destinations carries a destination mask, wherein each bit in the destination mask represents a corresponding destination processing block in the mesh architecture the data packet is sent to. The data packet traverses through the mesh architecture based on a routing scheme, wherein the data packet first traverses in a first direction across a first set of processing blocks and then traverses in a second direction across a second set of processing blocks to the first destination. During the process, the data packet is only replicated when it reaches a splitting processing block where the paths to different destinations diverge. The original and the replicated data packets are then routed in different directions until they reach their respective destinations.

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.
