通用一体化测试平台设计

针对航天控制系统灵活性、复用性、可扩展性较差等问题，采用部分动态可重配置和软硬件协同设计等技术，设计了一种基于Microblaze软核的高带宽软件无线电(Software-defined Radio，SDR)通用一体化测试平台。该硬件平台由Kintex7 FPGA与集成式射频(Radio Frequency，RF)收发器AD9371组成，采用Microblaze软核进行功能开发，实现任务调度、功能配置和数据交互；通过Vivado实现测试平台逻辑功能开发，并将功能代码封装成FPGA IP(Intellectual Property)核；最终通过AD9371 RF收发器实现射频数据收发。测试结果表明，该通用一体化测试平台可进行高速率、高带宽数据传输。该平台具有通用性强、互联性强、易操作、易移植等特点，可广泛应用于工业、通信、军事、医疗、汽车、无人机、航天等领域。

Design of a Universal Integrated Test Platform

For the problems of the poor flexibility,reusability,and scalability of aerospace control system,the technologies of hardware-software codesign and partial dynamic reconfiguration are used to design a high-bandwidth software-defined radio(SDR) universal integrated test platform based on the Microblaze soft core.This hardware platform consists of a Kintex7 field programmable gate array(FPGA) and an integrated radio frequency(RF) transceiver AD9371.Furthermore,the Microblaze soft core is used for function development to achieve task scheduling,function configuration and data interaction.The test platform logic function development is realized through Vivado,and the function code is packaged into the FPGA intellectual property(IP) core.Finally,the RF data is transmitted and received through the AD9371 RF transceiver.The test results show that the universal integrated test platform can perform high-speed and high-bandwidth data transmission.The platform has the characteristics of strong universality,strong interconnectivity,easy operation and transplantation,and it can be widely used in industry,communications,military,medical,automobile,and unmanned aerial vehicle,aerospace and other fields.
