VECTOR PROCESSING ENGINES EMPLOYING A TAPPED-DELAY LINE FOR CORRELATION VECTOR PROCESSING OPERATIONS, AND RELATED VECTOR PROCESSOR SYSTEMS AND METHODS

摘要

tap for providing the reduced sample material patches and / or precise correlation / covariance vector processing operations whose power consumption-the vector processing engine using the delay line (s) (VPE s) is initiated do. VPE disclosed herein are configured to provide correlation / covariance vector processing operation, such as CDMA (code division multiple access) correlation / covariance vector processing operation by way of non-limiting example. Tapping-delay line (s) contained in the data flow path between the memory and the execution units in the VPE. Tapping-delay line (s) is configured to provide to the execution unit for performing the correlation / covariance vector processing operation receives an input data sample vector set. Tapped-delay line (s) is further adapted shifting the input vector data set of samples for each of the filter delay taps, and to provide the shifted input vector data sample set to the execution unit, and thereby shift the inputted vector data sample set It does not need to be re-fetched from the vector data file for the processing operation of the filter vector.
