摘　　要：应用数字信号处理器设计了一个基于想象动作电位的脑-机接口系统,通过模拟滤波与数字信号器处理相结合的方法,实现了对想象动作电位信息的有效采集和处理。系统在硬件上设计了脑电信号放大器,DSP开发板;对脑电信号放大、AD转换后,通过分类特征提取处理后,完成动作识别与控制命令的输出。将数字信号处理器应用在脑-机接口中,利用数字信号处理器优异的处理能力和丰富的外设资源,实现了一个嵌入式、微型化的脑-机接口构建,实现了脑-机接口实时处理与微型化。This paper presents motor-imaginary-potential-based brain-computer interface （BCI） interface by using digital signal processor （DSP）. Combining analog filtering and digital processing; realize the motor imaginary potential information acquisition effectively and processing. A EEG amplifier and DSP development board were designed in system for hardware. Motor imaginary potential information through EEG-amplifier and AD converted, after classification and feature extraction, gesture recognition will be completed and control command will be output to control peripherals. In this paper, digital signal processor （DSP） is used in brain-computer interface （BCI）, using the DSP achieved a brain-computer interface real-time processing and miniaturization with its excellent processing power and rich resources of the peripheral. A on embedded technology Based,Miniaturization of brain-computer interface was built.
