基于ARM+FPGA的微陀螺仪数据采集处理系统设计

Design of data acquisition and processing system for micro-gyroscope based on ARM and FPGA

针对ADXRS610微陀螺仪,研究设计了基于ARM+FPGA的实时数据采集的嵌入式平台。主要介绍了采集系统的硬件组成与工作原理,对姿态结算的基本原理进行了分析,通过构建FPGA内部逻辑控制,解决了ARM与FPGA之间高速数据传递速度不匹配的问题,并通过实验对采集到的姿态数据进行了误差统计分析,结果表明数据可靠。

Aiming at micro-gyroscope of ADXRS610,an embedded real-time data acquisition platform based on ARM and FPGA is presented.Mainly introduce hardware composition and working principle of the acquisition system,analyze the basic principle of attitude calculation.The problem of mismatching of high-speed data transmission between ARM and FPGA is resolved by constructing FPGA internal logic control,and through experiment,error statistical and analysis on collected attitude data is carried out,the results show that the data is reliable.
