ABSTRACT:
A circuit for implementing a full search block matching algorithm for coding video signals sequentially receives pixel values from a block of pixels in a current video frame and sequentially receives pixel values from a search area of a previous video frame. The circuit includes a plurality of processors for calculating in parallel a group of error functions corresponding to a group of positions of the block in the search area. The error functions are compared for determining the block position having the minimum error function.
