the Micro-Grain Array Processor-2 (MGAP-2) is a two dimensional SIMD array of 49,152 fine-grain processors, designed primarily for high performance signal processing. Each processor can compute any one of 65,536 boolean transformations. What separates the MGAP-2 from existing fine-grain arrays is its processor level interconnect control. Each processor can independently select its communication direction. this allows a programmer to cluster groups of processors into larger computational units, and provides flexible interprocessor communication.

We present a single chip circuit solution to a concept called Near-Sensor Image processing, which includes image sensing, image processing and feature extraction. We give solutions to the three main implementation problems. A small photodiode read-out unit, which is locally compensated for process variations, a low power processor element and an instruction line driver, suitable for massively parallel processors are described. A 16 × 16 elements prototype has been built. However most of the results come from simulations of an improved 128 × 128 matrix.

A customized image processor for real time convolution of an image has been developed. Image convolution requires an extensive amount of calculation capacity and I/O communication which is hard to sustain with standard processors in real time. therefore, a customized processor has been designed with a tailored architecture. the processors have a total sustained calculation capacity of > 2G arithmetic operations/s at 20MHz clock frequency, surpassing that of TMS320C80 for this application due to the tailored architecture.
