Abstract: Based on FPGA and PCI bus,proposed design or motion controller.In this paper,introduced the system’s hardware structure,and there was a detailed description about how to achieve single-axis high-speed pulse output,linear interpolation,circular interpolation by FPGA.The implementation process of linear interpolation and circular interpolation were described,and some of the code were given.Finally the experiments prove that this system has the characteristics of high precision and reliable operation.
Key words: FPGA; PCI; motion controller; linear interpolation; circular interpolation
