Abstract :
The architecture of the elementary Processing Element - PE - used in a recently designed 128×128 Focal Plane Analog Programmable Array Processor is presented. The PE architecture contains the required building blocks to implement bifurcated data flow vision algorithms based on the execution of 3×3 convolution masks. The vision chip has been implemented in a standard 0.35 μm CMOS technology. The main PE related figures are: 180 cells/mm2, 18 MOPS/cell, and 180 μW/cell.
