| Abstract: | In textile machinery needle-election spending-control system, this paper gives out a design of the equal duty ratio arbitrary integer frequency divider based on FPGA. First introduces the characteristics and application domain of FPGA in brief. Then discusses a few traditional integer frequency dividers. Finally presents the frequency division theory and circuit design of dual modulus preset decimal frequency divider based on FPGA. The frequency divider is described in Verilog HDL and simulated with QUARTERSII6.0. |
