Abstract :
A 3 V 0.5 /spl mu/m CMOS analog IC correlates each 9/spl times/9 pixel window in an input image with 8 stored 9/spl times/9 templates at rates up to 5 MHz and outputs the best match. Core multiply-accumulators (MACs) use 5 pJ/multiply at 320/spl times/10/sup 6/ MAC/s for a 10/spl times/ energy improvement over digital ASIC MACs and 10/spl times/ over a general DSP. The overall IC performs data sequencing, 3.6/spl times/10/sup 9/ MAC/s, and max-finding, with 8 mV resolution, while consuming 420 mW.
