The FPGA is a new large—scale integrated logic IC. It is designed by EDA technology. And it has superiority over the TTL logic integrated gate. The article introduces realization method on the precise interpolation of quadratic interpolation in the FPGA, and emphatically discusses the pulse transmission module included odd frequency divider, even frequency divider and other auxiliary function modules. Each function module is described by the VHDL language and simulated on function and timing. And it has bring forward FPGA Precise Interpolation of Digital signal processor based on DSP-TMS320F28335 AC servo system. A motor’s closed-loop control system based on FPGA is introduced in this paper. High speed performance of FPGA chips is used to achieve real-time contro1.At the same time, new systems designs have been made out. By contacting the results of simulation and test, FPGA Precise Interpolation Devices can control the servo motor speed and direction with good flexibility, and meet the design requirements.
