With the rapid development of information technology , all kinds of portable electronic products and personal digital assistants are coming forth , the information source of these products partly roots in newspapers and journals , if the literal data could be acquired in optical scan mode instead of traditional keyboard input mode , human hands will be further liberated . on the other hand , the digital signal processor ( dsp ) specially designed for high - speed digital signal processing is playing an important role in the digital field , and the dsp with high processing speed and excellent operation performance is particularly adapted to image processing and character recognition . in consequence of this status , making use of new technology , this thesis researches into miniature intelligent reading system based on dsp and then presents a system solution of it 随着信息化技术的飞速发展，各种便携式电子产品和个人助理不断涌现，这类产品的信息来源有很大一部分都是报纸、书刊等文字资料，如果以文字的光扫描输入取代传统键盘输入将会进一步解放人的双手；同时专门为高速数字信息处理而设计的数字信号处理器( dsp )也成为数字化领域的重要角色， dsp的高速度和良好的运算性能特别适合于图像处理和文字识别。
