Function Module Based on FPGA System in Textile Machinery Control

摘要

This paper proposes a design of the equal duty ratio arbitrary integer frequency divider based on FPGA. First it introduces the characteristics and application domain of FPGA in brief, we 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 VHDL tool and simulated with QUARTERSII6.0.
