本文介绍了两种分频系数为整数或半整数的可控分频器的设计方法。其中之一可以实现50％的奇数分频。利用VHDL语言编程，并用QUARTERS||4.0进行仿真，用 FPGA 芯片实现。 关键词：半整数，可控分频器，VHDL, FPGA -This article describes two kinds of sub-frequency coefficient is an integer or half-integer divider controllable design method. One of them can achieve 50 of the odd-numbered sub-frequency. The use of VHDL language programming, and QUARTERS | | 4.0 simulation, using FPGA chip. Key words: semi-integer, controllable divider, VHDL, FPGA
