• abstract: A new smart-sensor VLSI circuit intended for focal-plane processing of grey-scale images is presented. The architecture is based on a fine-grain software-programmable SIMD array. Processing elements, integrated within each pixel of the imager, are implemented utilising a switched-current analogue microprocessor concept. In a 0.6 /spl mu/m CMOS process the cell size is equal to 98.6 /spl mu/m/spl times/98.6 /spl mu/m. A prototype 21/spl times/21 array chip executes over 1.1 GIPS (Giga Instructions Per Second) while dissipating below 40 mW of power and demonstrates a real-time performance on a variety of early vision tasks.
