Abstract:
A digital-to-analog converter (DAC) includes a mismatch shaping feedback vector quantizer configured to store state information in expanded format using One-Hot Encoding of a matrix. The expanded state format storage enables implementation of a simplified state sorter for the vector feedback mechanism of the vector quantizer. The simplified state sorter may minimize the variance of ones (or other symbols representing state values) in the matrix, and allow performing sorting in a reduced number of clock cycles. For example, sorting may be performed on a predetermined edge of single clock cycle, or on two edges of the same clock cycle. The matrix may be normalized periodically or as needed, to avoid overflow and underflow. The DAC may be used as a quantizer of a modulator of an access terminal in a cellular communication system.

Abstract:
Aspects of the present disclosure provide methods and apparatus for offloading checksum processing in a user equipment (UE) (e.g., from an application processor to a modem processor). Such offloading may speed up packet processing, increase data rate, and/or free up resources of the application processor for other tasks.
