Abstract :
A vision chip operating with 1.9pJ/OP efficiency has been fabricated in 0.18μm CMOS. Each of the 256×256 pixel-processors (dimensions 32×32μm), contains 14 binary and 7 analog registers coupled to a photodiode, an arithmetic logic unit, diffusion and asynchronous propagation networks. At the chip´s periphery, facilities exist to allow pixel address extraction, analog or digital readout. The chip has been exploited to conduct real-time image processing operations at 100,000fps, locating a closed-shape object from amongst clutter.
