    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 computing device can include a radio receiver to receive a radio signal from a radio transmitter of a second computing or communication device. The radio receiver can experience radio frequency interference. The computing device can also include a digital signal generator. The digital signal generator can be to process a signal (S1) underlying a source of the radio frequency interference. The digital signal generator can also be to generate a digital signal (S1). The digital signal generator can further be to inject the digital signal (S1) into the radio receiver to cancel the radio frequency interference around the radio frequency of interest.

    摘要: Embodiments of systems, apparatuses, and methods for correcting double bit burst errors using a low density parity check technique are disclosed. In one embodiment, an apparatus includes an encoder to generate a parity vector by multiplying a first version of a data vector by a matrix. The parity vector is to identify correctable double-bit burst errors in a second version of the data vector. The apparatus also includes logic to concatenate the parity vector and the first version of the data vector.
