Multi-bit Gray Code Counter Based on FPGA

摘要

According to the characteristics of Gray code,a method of separate count is presented. The 32-bit Gray code counter is programmed with VHDL on the platform of Quartus 2,and the simulation waveforms are achieved. The results indicate that Gray code counter counts accurately in the case of high clock frequency and obviously eliminates the emergence ofglitch. Compared with the ordinary binary counter,it has high stability and flexibility. This method is a reference to Hesicrn of counter.
