METHOD AND SYSTEM FOR PERFORMING MOTION ESTIMATION USING LOGARITHMIC SEARCH

A method, apparatus,and system for performing motion estimation using a logarithmic search are described. One or more image signal processing engines including a plurality of processing elements are employed. The one or more image signal processing engines are mutually coupled by a register file switch, and the one or more image signal processing engines perform a block matching calculation that includes a sum of absolute differences. The plurality of processing elements is further mutually coupled such that, during the block matching calculation, parallel processing and pixel data sharing of reference block pixel locations is employed by the plurality of processing elements.
