IRIS: An integrated, scalable focal plane architecture

Wearable video processing systems integrate low cost silicon detectors and analog interface circuitry with massively parallel digital processing on a single chip. While this `imaging system on a chip' can enable many significant new systems, many architectural and technological challenges must be addressed. This paper presents the IRIS architecture in which a detector, analog interface circuitry, and massively parallel digital processing is integrated into a cell that can be tiled into a monolithic array. This pixel level integration offers significant performance, efficiency, and cost advantages over multi-chip and non-interleaved approaches. The IRIS architecture and an example system is described.
