Abstract: Techniques that enable calibration of digital-to-analog Converters (DACs) with minimal processing overhead. A single frequency bin can be used to calibrate errors between bits. A low frequency feedback path can be included into a low frequency low power ADC to determine the error signal that exists in the calibration bin. The bits are calibrated when this error signal is minimized. The calibration techniques described provide an extremely efficient and optimal calibration at the DAC output of both static and dynamic errors.

Abstract: A system, method, and computer program product for dividing two binary numbers. The divider implements a fixed point division function using a floating point normalization architecture to yield the closest initial quotient approximation. The divider normalizes the input dividend and divisor to a range of [0.5, 1.0) by scaling each by necessary factors of two. The normalized inputs are submitted to a divider core that may be optimized for dividing inputs of such limited ranges. The divider core output is then rescaled by an appropriate factor of two, appropriately signed, and loaded into saturating registers for output in various formats. The divider core progressively outputs quotient bits in decreasing order of significance until a predetermined level of precision is reached, typically fewer bits than in a complete quotient, for faster output. One embodiment generates the six most significant quotient bits in one clock cycle.

Abstract: A packet detection technique is disclosed in which an average correlation signal is generated representative of the match between a repetitive sequence of symbols; an average power signal is generated representative of the average power in the sequence of symbols; a scaled magnitude of the average correlation signal scaled by a first predetermined scale factor is produced; and one of the average power signal and scaled magnitude of the average correlation signal are multiplied by the second scale factor and compared to determine whether there is a match between a repetitive sequence of symbols.
