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 CycloneⅡseries EP2C5Q208C 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.
