摘　　要：本文介绍了一种基于FPGA的多数值分频器的设计,该分频器可以实现占空比及分频系数可调,其分频数值可以是整数、小数和分数。文章给出了使用Altera公司的Cyclone II系列EP2C5Q208C型FPGA芯片中实现后的仿真结果和测试结果,这些结果表明设计的正确性和可行性。分频器采用VHDL语言编程实现,用户可以自行设置分频器功能,这种分频器设计具有很强的实用性和可移值性。A multi-value frequency divider design based on FPGA is described, it can achieve that its the duty cycle and the frequency division factor are adjustable, the dividing valve can be integer, decimal or fractional. The simulation results and the test results are showed, the frequency divider use Altera Corporation Cyclone Ⅱ series EP2CSQ208C chip to complete the configuring and functions, the test results showed that the design is correctness and feasibility. The frequency divider is programmed by VHDL language, users can set its function by self, the frequency divider design has very practical and portability.
