摘　　要：运用片上可编程系统(SoPC)技术,设计二频机械抖动激光陀螺信号处理系统。该系统以嵌入式软核处理器Nios II为核心,对输出信号进行数字滤波,并协调控制高压电源、稳频、抖动驱动与噪声注入等工作单元。使用该系统对某型国产二频机抖陀螺进行测试,结果表明该系统测得的陀螺输出信号可达0.002°/h的精度,系统运行稳定可靠,能够有效控制陀螺的工作参数并监测其运行状态,达到预期的设计要求。Taking advantage of SoPC technology,an integrated signal processing system for ring laser gyro （RLG）is designed,which is based on Nios Ⅱ soft core processor.In the system,the RLG＇s read-out signal is filtered,meanwhile the system controls the high voltage unit,path long control（PLC）unit and dither unit effectively. The testing experiment of the domestic RLG using this system shows that the output signal achieves the accuracy of 0.002°/h,and the system controls and monitors the RLG with high stability, which meets the proposed requirement.
