摘　　要：针对现有的常用分频器的使用局限性,介绍了一种可以实现任意小数、分数分频的新型分频器。由预先设置的分频参数,通过使用一个带余数输出的除法器,计算出其商和余数,以确定两个分频器的分频系数和分频次数,通过控制两个分频器交替工作,从而实现任意分频。分析了这种新型分频器的工作原理,提出了一种简单的实现电路,并用VerilongHDL语言描述了该分频器,在FPGA上运行实现,通过仿真证明其可行性。Due to the limitation of the frequency dividers recently widely used,in this thesis, a new type of frequency divider is introduced. By the parameter set before,the quotient and remainder can be calculated by a divider with output of remainder,which are used as the division parameter and dividing times of the two dividers. By controlling the two dividers working by turns,the new divider is implemented. In this thesis, the principle and the way of implementation are introduced, then circuits is introduced and described by Verilog - HDL,finally,it is implemented on FPGA. With FPGA simulation,the feasibility is proved.
