The thesis will be established as prototype of DSP-Based motion control card with USB2.0 interface. The whole system is composed of three subsystems: 1. Windows AP¡]Application Program¡^, 2.USB2.0 development tools, and 3.DSP development tools. Many motion control commands can be transmitted from friendly AP, through USB2.0 development board, to DSP development board, for example, position, velocity and acceleration. DSP will parse and execute these commands immediately; furthermore, the course and result of processing can be sent back to host by the same route. Then AP can display the data received from target with high readability. In a word, proved by experiment, the thesis achieved the expected goal: accomplish the prototype research and development of DSP-Based motion control card with USB2.0 interface.
