Abstract: In order to solve the complicated problems in circuit design of universal IRIGB time coding technology nowadays,IRIG-B time coding techniques are further researched and a new single-chip solution based on FPGA(Field Programmable Gate Array) is developed. Furthermore, coding algorithm with combination of VHDL hadware and C-language software is designed,which makes the IRIG-B time code realized and can be applied.The coding technology offers many advantages such as simple algorithm,high accuracy,good portability,which has good application prospects and better economic benefits.
