Abstract

This paper describes a full-custom mixed-signal chip which embeds distributed optical signal acquisition, digitally- programmable analog parallel processing, and distributed image memory--cache--on a common silicon substrate. The paper briefly describes the chip architecture and focus mostly on presenting experimental evidence of the chip functionality. Multiscale low-pass and high-pass filtering of gray-scale images, analog edges extraction, image segmentation, thresholded gradient detection, mathematical morphology operations, shortest path detection in a labyrinth, skeletonizing, image reconstruction, several non- linear type image processing tasks like absolute value calculation of gray-scale gradient detection and real-time motion detection in QCIF video sequences are some of the very interesting applications that have been demonstrated as available when using the prototype.
