Abstract
A parallel processing logic circuit for sensor signal processing includes sensors and processing units. The sensor and the processing unit are integrated in the same pixel and arranged in a matrix. The processing unit contains a logic structure that consists of a register and a combinational logic function to execute pixel-parallel processing, based on binary data for a sensor, other processing units, and itself. The combinational logic function performs only a predetermined logic function and its dual one exclusively, thereby sharing the circuit resource and reducing the size of the processing unit. The register focusing on compactness also contributes to the small unit.
