在對(duì)AOS系統(tǒng)進(jìn)行功能模塊劃分的基礎(chǔ)上,介紹了系統(tǒng)中一個(gè)非常關(guān)鍵的組成部分下行
鏈路控制器。該方案采用我國自主知識(shí)產(chǎn)權(quán)的核心器件--方舟系列CPU芯片，在Linux操作系統(tǒng)下設(shè)計(jì)與實(shí)現(xiàn)下行鏈路控制器，并給出了其主要的工作流程。試驗(yàn)結(jié)果表明該下行鏈路控制器較好地實(shí)現(xiàn)了多路數(shù)據(jù)的包裝與復(fù)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.
