基于NiosⅡ软核的LSINS数据采集与预处理

摘要

A design for data acquisition and pretreatment of LSINS based on soft core of Nios II is proposed. The formal configuration of DSP + FPGA with a single FPGA chip EP1C12Q24017N transplanted with Nios II is replaced. With the debugging work of software and hardware, it' s proved that in this way. The data acquisition and pretreatment of LSINS takes on the character of low cost, quite credibility, high precision, fast rapidity and so on.%提出了一种基于NiosⅡ软核的激光捷联惯导数据采集与预处理实现方案.以移植了NiosⅡ软核的FPGA芯片EP1C12Q24017N取代原来系统DSP+ FPGA的结构.该方案通过了硬件与软件的调试,证明了此方案实现的激光捷联惯导数据的采集与预处理具有成本低、运行可靠、精度高、速度快等特点.
