摘要： Embodiments include systems and methods for RFI mitigation in a wireless computing environment. In one embodiment, a platform determines RFI information of the platform by listening with a receiver of a transceiver of the platform when the transmitter of the transceiver is quiescent. The platform derives Frequency Domain Weights from the RFI information and transmits the Frequency Domain Weights to a Wireless Access Point (WAP). In the transmitter and receiver of the WAP, the Frequency Domain Weights are applied to signals received and to be transmitted.

摘要： Apparatuses, systems, and methods that employ conditional probabilities to calculate phase errors are disclosed. For a received signal, the embodiments may develop several phase error estimates relative to each point of a constellation, the number and location of points of the constellation depending on the modulation technique of the received signal. In addition to calculating the phase error estimates, the embodiments may also calculate weights, or probabilities, associated with each of the estimates. The embodiments may use the estimates and the weights to calculate a composite phase error estimate. The composite phase error estimate may be used to correct the received signal and eliminate or reduce the impact of the phase error.

摘要： Methods and apparatuses to support memory transactions using partial physical addresses are disclosed. Method embodiments generally comprise home agents monitoring multiple responses to multiple memory requests, wherein at least one of the responses has a partial address for a memory line, resolving conflicts for the memory requests, and suspending conflict resolution for the memory requests which match partial address responses until determining the full address. Apparatus embodiments generally comprise a home agent having a response monitor and a conflict resolver. The response monitor may observe a snoop response of a memory agent, wherein the snoop response only has a partial address and is for a memory line of a memory agent. The conflict resolver may suspend conflict resolution for memory transactions that match the partial address of the memory line until the conflict resolver receives a full address for the memory line.

摘要： Methods and arrangements to correct for double rounding errors when rounding floating point numbers to nearest away are described. Embodiments include transformations, code, state machines or other logic to perform a floating point operation on one or more floating point numbers of precision P1 in base b, producing positive result res0 of precision greater than precision P1; rounding positive result res0 to precision P1 to the nearest away, producing positive result res1; and rounding the result res1 to precision P2 to the nearest away, where P2 is narrower than P1, producing result res2. The embodiments may also include correcting res2 for double rounding errors. The correcting may include determining that res1 is midway between two consecutive floating point numbers of precision P2, the larger being res2, determining that rounding res0 to produce res1 involved rounding up, and decrementing the significand of res2 to obtain the corrected result.

摘要： A sampling clock signal controller for receivers of digital data is disclosed. Specific bit patterns of a data waveform can be identified, and stored time samples of the waveform that correspond to the specific bit patterns can be analyzed to improve the timing of a sampling clock signal. These “time-amplitude” samples on known bit patterns can be utilized to determine if a sample on the data waveform should be taken before the center of the eye pattern, at the center of the eye pattern, or after the center of the eye pattern and by what time change. Accordingly, a single low power clock can be utilized to adjust the timing of the sample clock such that improved communication scan be achieved. Such a single clock system has reduced power requirements and increased accuracy.
