Simplification of Motion Controller Based on DSP IO Space and CPLD

A method is designed for the simplification of multi-function motion controller, based on the DSP I/O space and CPLD. The core technology is the use of the rich I/O space of the DSP and the powerful logic capabilities of CPLD. Using this method, the reuse of the DSP bus can be achieved. Compared with the traditional motion controller, the simplified motion controller significantly reduces both the hardware resources and the complexity of the motion controller. It increases the reliability and versatility of the motion controller. Development cycle is shorter and easier to maintain. This method is suitable for real-time signal processing.
