A 100,000 fps vision sensor with embedded 535GOPS/W 256×256 SIMD processor array

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.
