ACE16k: A Programmable Focal Plane Vision Processor with 128 x 128 Resolution

چکیده
* --This paper presents a new generation 128x128 Focal Plane Analog Programmable Array Processor (FPAPAP), from a system level perspective. The design has recently sent to fabrication in a 0.35μm standard digital 1P-5M CMOS Technology. The chip has been designed to achieve the high-speed and moderate-accuracy constraints of most real time image processing applications. It has been designed to be easily embedded in conventional digital hosting systems: external data interchange and control are completely digital. The chip contains close to four millions transistors, 80% of them working in analog mode, and exhibits a relatively low power consumption (<4W, i.e. less than 1mW per transistor). Experimental results are expected for the date of paper presentation.
