摘要： A serial point to point link that communicatively couples an integrated circuit (IC) device to another IC device is initialized by transferring a training sequence of symbols over the link. Registers of the IC device are programmed, to set a symbol data pattern and configure a lane transmitter for the link. A start bit in a register of the IC device is programmed, to request that the link be placed in a measurement mode. In this mode, the IC device instructs the other IC device to enter a loopback mode for the link. The IC device transmits a sequence of test symbols over the link and evaluates a loopback version of the sequence for errors. The sequence of test symbols have a data pattern, and are transmitted, as configured by the registers. Other embodiments are also described and claimed.

摘要： A transmitting device and a receiving device are coupled together via an interconnect. An electrical idle ordered set is received at the receiving device power management unit after having been transmitted by the transmitting device and received at the input pins of the receiving device and moving through the receiver logic pipeline. At the time the electrical idle ordered set has been recognized at the end of the receiver logic pipeline, the power management unit checks for activity on the interconnect. If there is no activity on the interconnect, then the power management unit causes the receiving device to enter a low power state where the receiver circuitry (input buffers) is turned off. If there is activity on the interconnect when the electrical idle ordered set is received at the power management unit, then the power management unit does not cause the receiver circuitry to be turned off.

摘要： A stream of bits are received in a first integrated circuit (IC) device, where the stream represents a sequence of symbols transmitted by a second IC device over a serial point to point link that couples the two devices. First and second M-bit sections of the stream are compared to a non-data symbol. The second M-bit section is offset by one bit in the stream relative to the first section. If there is a match between the first section and the non-data symbol, then a flag indicating symbol alignment is asserted. Each of multiple, consecutive, non overlapping M-bit sections that follow the first section are then to be treated as separate symbols. Other embodiments are also described and claimed.

摘要： Multiple symbol sequences that have been transmitted in parallel using the same transmit clock over a serial point to point link are received. Each symbol sequence includes an instance of a first, non-data symbol. The multiple symbol sequences are buffered and the number of times an instance of a second, non-data symbol that occurs in one of the symbol sequences is changed. A first deskew process is performed, followed by a second deskew process. The first deskew process aligns an instance of the first non-data symbol in every one of the buffered symbol sequences. The second deskew process equalizes the number of instances of the second non-data symbol that follow an instance of the first non-data symbol in every one of the symbol sequences. Other embodiments are also described and claimed.
