摘　　要：本文介绍了一种能够完成半整数和各种占空比的奇/偶数和的通用的分频器设计,并给出了本设计在Altera公司的FLEX10K系列EPF10K10LC84-3型FPGA芯片中实现后的测试数据和设计硬件的测试结果,结果表明了设计的正确性和可行性。由于设计采用VHDL硬件描述语言实现,用户可以自行裁减和设置分频器的功能,所以有很广泛的应用价值。This paper presents an algorithm for designing a universal frequency divider which can realize different duty cycle either odd and even divider number. Experiments and hardware test on Ahera PF10K10LC84-3 chip of FLEX10K series are given to show that the design is successful. Depending on the VHDL realization of this algorithm the design is of design flexibility and widely applications.
