摘　　要：针对现在MEMS陀螺仪的精度还不高的状况,为了降低陀螺仪信号的噪声,改善其非线性性能,提高陀螺仪信号的精度,提出基于TI公司的数字信号处理器TMS320VC33的MEMS陀螺信号实时采集与处理系统,对MEMS陀螺信号进行降噪、非线性补偿处理;并在DSP多任务机制下实现数据采集、处理、传输的并行化,该信号处理平台信号处理时间短,实时性高,可以满足MEMS陀螺仪的使用要求,算法简单有效,可以显著降低MEMS陀螺信号的噪声,在实际应用中具有一定的参考意义。Because the MEMS gyroscope is not high accuracy, for reducing the signal and improving the MEMS gyroscope signal＇s accuracy, TMS320VC33, the new DSP chip producted by TI company is used in the signal processing platform. MEMS gyroscope signal processing platform is designed by combing operating system and used for denoising,nonlinear compensation process. This system makes a good effect in practical appliance because of its simple structure, small bulk, easy to integration and real - time.
