Zynq异构多核的无线电信号采集终端系统设计

针对无线电管理部门大规模信号监测的应用需求,设计了一种基于异构多核 Zynq-7000的嵌入式无线电信号采集监测系统.该系统在硬件上采用了射频捷变收发器AD9361作为接收前端,Zynq-7000作为处理核心;在软件上实现了 NEON和 VFP的硬件加速,以 QT为框架开发了用户显示界面.在详细阐述该终端在硬件逻辑设计、嵌入式设计和应用软件设计的基础上,通过试验展示了其所具有的数据采集、频谱监测和数据可视化等功能.这为轻便、灵巧、低成本、便携式无线电信号监测系统的研发提供了重要参考.

Radar Signal Acquisition Terminal System Based on Zynq

Aiming at the application requirements of large-scale signal detection in radio management department,an embedded radio sig-nal acquisition and monitoring system based on heterogeneous multi-core Zynq-7000 are designed.The design adopts RF agile transceiver AD9361 as the receiving front-end and Zynq-7000 as the processing core in hardware.The hardware acceleration of NEON&VFP is im-plemented,and the user interface is developed based on QT in software.After elaborating on the basis of hardware logic design,embed-ded design and application software design,the terminal achieves the functions such as data acquisition,spectrum monitoring and data vi-sualization.This provides an important reference for the development of portable,smart,low-cost,portable radio signal monitoring systems.
