Abstract :
In this paper an architecture is described that implements motion estimation in image coding, using a block-matching algorithm and an exhaustive search method. The architecture, EST256, consists of 256 processor elements, deals with a search area of -8/+7 and performs 11 GOPS (subtraction, absolute value determination, accumulation and comparison). It is implemented with ES2 0.7 μm double-metal-layer CMOS technology. This ASIC is cascadable to deal with bigger search areas
