| Abstract(in English) | Gabor filtering is useful for intelligent image processing, but it requires huge computational power. Pixel-parallel LSI implementation is one solution for real-time image processing. We have already proposed a new pixel-parallel Gabor filtering algorithm using transient states of resistive networks. This paper describes an LSI implementing this algorithm. This LSI has been designed using 0.35μm CMOS technology and based on the merged analog-digital circuit architecture using pulse-width modulation (PWM) signals. The LSI with a die size of 9.8 mm sq. includes 61 × 72-pixel processing units, and its maximum operation performance is 26 GOPS. |
