Abstract :
A programmable silicon retina is presented targeting the use of efficient analog computation for early vision. The decoding and programmability methods employed lead to a dynamic and wide range of vision operations including edge enhancement, edge detection and averaging. A prototype chip implementing a 15×15 matrix of photo-receptors was fabricated in a double poly double metal N-well 2 μm process.
