Paper Abstract

In this paper, a programmable accelerating chip with parallel and pipelined computation capabilities for optical Chinese character recognition (OCCR) is presented. The chip contains eight matching processing elements working in parallel and a memory-saving sorter which can choose the best 32 candidates. The structure of the design is flexible and modular, which is capable of processing different start points and end points of the template feature. Fabricated in 1.0 micron CMOS gate array, the chip contains approximately 16,000 gates. It has been tested to be fully functional. By using this chip, a powerful optical Chinese character recognition system with high speed, high recognition rate, and accumulated learning ability is developed. From the experimental results, the process speed of this chip can be up to 200 characters per second, which is one hundred times the conventional pure software process speed. The chips can be used in parallel for a larger template character system and will not increase the process time.
