An engineering signal processing scheme based on TI’s TMS320C6711 processor is proposed. The principle and testing method of closed loop fiber optic gyroscope are introduced. The choice of ADC and DAC is analyzed theoretically, and the hardware and software of the closed-loop FOG digital processing system are designed. The use of efficient McBSP mouth and peripheral ADC, DAC communication, the use of JATG mouth real-time monitoring of DSP work process, and to upgrade the program. In response to the real-time requirements of the gyro system, an efficient digital filtering algorithm that meets the accuracy requirements was developed.
