Abstract: For the requirement of designing open motion controller, a solution of designing a four-axis motion controller based on digital signal processor(DSP) and field programmable gate array(FPGA) was presented. The characteristic of the architecture, the design of the hardware and software modules, and the analysis of FPGA logic modules of the motion controller system were discussed in detail. The idea of modularization from PC/104 architecture was absorbed, based on the external interface of TMS320F2812 DSP, and the EP2C5 FPGA chip with high cost performance, specific peripheral circuit was adopted. Therefore, this system has the characteristics of simple framework, lower cost, open and modularization. Additional, the modules based on the local bus can be implemented respectively, which makes design easily. The results of practical application show that the controller has good performance.
