高级在轨系统下行链路控制器的设计与实现

在对AOS系统进行功能模块划分的基础上,介绍了系统中一个非常关键的组成部分下行
链路控制器。该方案采用我国自主知识产权的核心器件--方舟系列CPU芯片，在Linux操作系统下设计与实现下行链路控制器，并给出了其主要的工作流程。试验结果表明该下行链路控制器较好地实现了多路数据的包装与复用。

Abstract: This paper discusses a method of AOS functional partition, presents a down
network controller accord with AOS (Advanced Orbiting System) standard. The network
controller is very important devices in the system. By making use of an independent
intelligent property right of our country of the core spare part-ARCA series CPU
chip, design and carry out the network controller under the Linux operate system,
and give its main process. Carry on imitating a true verification .The simulation
result shows that the controller can evaluate the packaging and multiplexing of the data
with properly.
