    Abstract: A method and apparatus in which a data stream is received that includes constant bit rate (CBR) carrier streams, at least one of which comprises frames, a cumulative phase offset report (CPOR) and a client rate report (CRR). A counter accumulating a PHY-scaled stream clock (IPSCk) is sampled at a nominal sampling period (Tps) to obtain a cumulative PHY-scaled count (CPSC). A PHY-scaled stream phase offset (PSPO) is calculated that indicates phase difference between PHY-scaled stream nominal bit count (LPSD) and an incoming PHY-scaled count delta (IPSD). The data stream is demultiplexed to obtain CBR carrier streams. Respective CBR carrier streams include a previous network node CPOR (CPOR-P) and a previous network node CPO (CPO-P). A CPO is calculated that is a function of CPO-P and PSPO. CPO-P is replaced with the calculated CPO. The CBR carrier streams are multiplexed into intermediate-network-node data streams that are transmitted from the intermediate-network-node.

    Abstract: A method and apparatus in which a data stream generated by a previous network node, a cumulative phase offset report (CPOR) and a client rate report (CRR) are received. A counter accumulating a PHY-scaled stream clock (IPSCk) is sampled at a nominal sampling period (Tps) to obtain a cumulative PHY-scaled count (CPSC). A PHY-scaled stream phase offset (PSPO) is calculated that indicates phase difference between a PHY-scaled stream nominal bit count (LPSD) and an incoming PHY-scaled count delta (IPSD), where IPSD indicates CPSC increment between successive CPSC samples. The data stream is demultiplexed to obtain CBR carrier streams that include a previous network node CPOR (CPOR-P) and a previous network node CPO (CPO-P). A CPO is calculated that is a function of CPO-P and the PSPO. CPO-P is replaced with the calculated CPO. The CBR carrier streams are multiplexed into intermediate-network-node data streams that are transmitted from the intermediate-network-node.

    Abstract: A network switch and associated method of operation for establishing a low latency transmission path through the network which bypasses the packet queue and scheduler of the switch fabric. The network switch transmits each of a plurality of data packets to the identified destination egress port over the low latency transmission if the data packet is identified to be transmitted over the low latency transmission path from the ingress port to the destination egress port, and transmits the data packet to the destination egress port through the packet queue and scheduler if the data packet is not identified to be transmitted over the low latency transmission path from the ingress port to the destination egress ports.

    Abstract: A redundant angular position sensor comprising a first angular position sensor including a first excitation coil, a first sensing coil and a second sensing coil and a second angular position sensor. The second angular position sensor including a second excitation coil, a third sensing coil and a fourth sensing coil. Each of the first, second, third and fourth sensing coils comprising a respective clockwise winding portion and a respective counter-clockwise winding portion. The redundant angular position sensor further comprises a rotatable inductive coupling element positioned in overlying relation to the sensing coils and separated from the sensing coils by a gap, wherein the rotatable inductive coupling element comprises four, substantially evenly radially spaced, sector apertures.

    Abstract: In one implementation devoid of an effective address generator a method of call operation comprises pushing one or more parameters onto a first stack, pushing the contents of one or more registers onto a second stack, popping off the first stack one or more of the parameters into one or more of the registers whose contents were pushed onto the second stack, performing register to register operations on the one or more registers whose contents were pushed onto the second stack with a result of the register to register operations being stored in a result register, the result register being one of the one or more registers whose contents were pushed onto the second stack, popping off the second stack the contents of all the one or more registers into their respective registers from which they came, and returning control to an instruction following the call.

    Abstract: A system and method for double data rate (DDR) chip-kill decoding using an array of ECC erasure decoders operating in parallel to identify a location of a chip-kill event associated with a DDR memory device. The ECC erasure decoder that correctly identifies the chip-kill location is then used to decode subsequent DDR bursts transmitted from the DDR memory device.

    Abstract: An angular position sensor comprising two annular sensors, one annular sensor for generating a coarse resolution time varying signal in the presence of a rotatable inductive coupling element and the other annular sensor for generating a fine resolution time varying signal in the presence of the rotatable inductive coupling element. The rotatable inductive coupling element comprising a first annular portion comprising at least one annular conductive sector and at least one annular non-conductive sector and a second annular portion comprising at least one annular conductive sectors and at least one annular non-conductive sector, wherein the number of annular conductive sectors of the first annular portion and the second annular portion are different. In particular, the annular conductive sectors of the annular portions may comprise 50% or 75% of the total area of the annular portions.
