Paper Abstract

In this paper, a four-channel associative memory based on multiplexed synchronizing data processing has been presented, whose processing speed is four times as fast as that of one- channel memory. The storage unit and the processing unit has also been separated. Photorefractive KNSBN crystals are used as storage media, and a liquid crystal photoelectric switch (LCPS) is selected to perform the thresholding feedback and gain operation. The experimental results show that some important parameters, including processing speed, output quality, etc., have been improved a lot, and the system can process natural images in real- time.
