中文摘要:
      为便于提取射频信号两正交分量进行分析,以赛灵思FPGA架构为平台,基于其内嵌高速串行收发模块,设计了基于Aurora的多通道高速可配置数据采集系统.系统可通过多速率时钟发生器LMK03806输出改变高速AD的采样时钟实现采样率可配置.系统底层硬件参数都通过程序封装为控制字指令的形式,可由上位机下发串行指令实时控制.最终实现了多通道一致性且采集工作同步实时进行,采集后的数据经过对齐、排序、打包后基于高速串行协议上传准确无误.
英文摘要:
      In order to extract the two orthogonal components of RF signal for analysis, A high-speed configurable multi-channel data acquisition system based on Aurora is designed based on the embedded high-speed serial transceiver module. The system can change the sampling clock of high speed AD through the output of multi-rate clock generator LMK03806 to realize the configurable sampling rate. The underlying hardware parameters of the system are encapsulated in the form of control word instructions, which can be controlled in real time by serial instructions issued by the upper computer. Finally, the multi-channel consistency is realized and the collection work is synchronized and real-time. The collected data is uploaded accurately based on high-speed serial protocol after alignment, sorting and packaging.
