A CMOS Resistive-fuse Processor for 2-D Image Acquisition, Smoothing, and Segmentation

Abstract

An integrated CMOS resistive-fuse processor capable of smoothing out noise while preserving the edges of a 32×32 image is described. An on-chip photo-transistor imager converts the optical image into electrical currents. The design of a single-pixel processing element using resistive fuses is described. The processed output is read out using a row decoder and a column MUX. Operating from a single 5-V supply, the chip typically dissipates only 10 mW.
