Title:
SYSTEM AND METHOD OF MAPPING MULTIPLE REFERENCE FRAME MOTION ESTIMATION ON MULTI-CORE DSP ARCHITECTURE
Document Type and Number:
WIPO Patent Application WO/2014/083491
Kind Code:
A3
Abstract:
System and method of mapping multiple reference frame motion estimation on a multi core digital signal processor is disclosed. The method includes considering at least one motion vector of a plurality of neighbouring macro blocks present in a current frame and a co-located frame to find a best prediction point motion vector set, collecting a best data block among a plurality of data blocks from a plurality of reference frames according to a plurality of sets of motion vectors at a first pipeline stage, transmitting a data searched related to the plurality of sets of motion vectors from the second level of memory to a first level of memory of a second digital signal processor at a second pipeline stage and finding a best motion vector by utilizing a cost based search on the second digital signal processor is performed at third pipeline stage.
