A CMOS image sensor/processor chip fabricated in a 0.35 µm CMOS technology is presented. The chip contains a general purpose software-programmable SIMD array of 128×128 processing elements. It executes over 20 GOPS while dissipating 240 mW of power and achieves pixel-processor density of 410 cells/mm2. Performance and accuracy measurement results are given.
