The central of controller is DSP,FPGA is used for extending and managing peripheral interfaces. The in-out signals have different ways; serial communication can be setting different modes. Therefore, the controller has great universality. The controller has merits of DSP and FPGA. Consequently, it is integration, flexibility, universal, high speed and high precision. The controller satisfied different situation.%以DSP作为核心，配以FPGA作为外围接口扩展和管理，进行了控制器设计。通过A／D采样和正交编码QEP，可以获取不同类型传感器的输入信号；D／A和PWM可以输出模拟和数字的控制信号；扩展的多路串口通信电路也可以配置为不同的工作模式，保证了控制器对于不同场合的适用性。DSP强大的数据运算能力与FPGA的灵活性相结合。使得控制器具有灵活性好、通用性强以及高速、高精度的特点，满足多种场合应用。
