A flexible block matching motion estimation chip is described with variable sized blocks between 8×8 and 32×32 pixels. Each chip performs block matching with a search area of ±15 vertically and horizontally for a block size of 32×32. For larger search areas devices can be cascaded. Besides full search, fast algorithms can be emulated. Sub-pel precision motion vectors can be calculated using a smaller search area or cascading devices. The chip will have a computational power of more than 200 GOPS and a die size of 170 mm2 in an 0.5-μm CMOS technology
