摘要：

A new approach to an analog ultra-low power medium-resolution vision chip design is presented. The prototype chip performs low-level image processing algorithms in real time. Only a photo-diode, MOS switches and two capacitors are used to create an analog processing element (APE) that is able to realize any convolution algorithm based on a full 3 x 3 kernel. The proof-of-concept circuit is implemented in 0.35 mu m CMOS technology, and contains a 64 x 64 SIMD matrix with embedded APEs. The matrix dissipates less than 0.3 mW (less than 0.1 mu W per APE) of power under 3.3 V supply, and its image processing speed is up to 100 frames/s.
