KDA3.2-050-3-AP0-U1拐進(jìn)熱鬧的北京南中軸線，進(jìn)入中國運(yùn)載火箭技術(shù)研究院旁邊的一處院子，頓時(shí)清靜了許多。梧桐綠意盎然，科研樓錯(cuò)落有致。在這里，中國航天科技集團(tuán)公司九院772所所長趙元富團(tuán)隊(duì)研制出的國產(chǎn)CPU芯片，首次全部使用在新一代北斗導(dǎo)航衛(wèi)星上。為了這一天，趙元富和他的團(tuán)隊(duì)走過了10年。
KDA3.2-050-3-AP0-U1此次登上北斗雙星的宇航級(jí)國產(chǎn)CPU芯片，產(chǎn)品性能已基本達(dá)到國際先進(jìn)水平?！霸谀承┛馆椛渲笜?biāo)上，我們比國外的一些產(chǎn)品還更有優(yōu)勢?！壁w元富自信地說。
一條道路
核心芯片關(guān)乎信息安全，要掌握核心技術(shù)只能走自主研發(fā)之路
趙元富是江西進(jìn)賢人，還是放牛娃時(shí)，他就一直好奇半導(dǎo)體收音機(jī)何以能發(fā)出響聲，上大學(xué)時(shí)，他選了半導(dǎo)體物理和器件專業(yè)。1983年，趙元富在我國著名航天微電子技術(shù)專家黃敞先生的指導(dǎo)下攻讀碩士學(xué)位，開始從事抗輻射技術(shù)研究，從此，他越來越深刻地認(rèn)識(shí)到抗輻射技術(shù)對國家航天發(fā)展的重要作用。“核心技術(shù)是無法依靠別人的，這是基礎(chǔ)能力?！壁w元富回憶道。
KDA3.2-050-3-AP0-U1信息安全是國家戰(zhàn)略問題，其硬件支撐就是核心芯片。目前，我國芯片主要依賴進(jìn)口，我國每年因芯片進(jìn)口要花費(fèi)2000多億美元，和進(jìn)口石油的花費(fèi)差不多。對于空間應(yīng)用的芯片而言，還要具有抗輻射等特殊性能。因?yàn)橛钪婵臻g環(huán)境極為復(fù)雜，大量的空間粒子輻射會(huì)導(dǎo)致星上電路性能退化甚至功能失效，對衛(wèi)星造成致命打擊。
“但除了航天員，誰也沒有去過太空?！币诘厍蛏习烟绽锟赡苡龅降膯栴}想清楚，難度可想而知。
KDA3.2-050-3-AP0-U1拿芯片來說，百姓日常使用的手機(jī)等電子產(chǎn)品被稱為“電子行業(yè)”。而航天器上使用的芯片要經(jīng)受太空嚴(yán)酷環(huán)境的考驗(yàn)，因其特殊需求被稱為“行業(yè)電子”。1996年，趙元富得到一次出國研究的機(jī)會(huì)，在兩年多研究中，他更清晰地看到了國內(nèi)外抗輻射技術(shù)的巨大差距。面對外國導(dǎo)師提供的工作機(jī)會(huì)，趙元富最終還是選擇回國，對他而言，回國無需答案，既然選擇了研發(fā)“中國芯”，就得走到底。
KDA3.2-050-3-AP0-U1“這個(gè)被喻為衛(wèi)星大腦和心臟的家伙，體現(xiàn)了中國航天的核心基礎(chǔ)技術(shù)能力?！壁w元富自豪地說，“為了實(shí)現(xiàn)中國航天芯片的自主可控，不管多難，我們都要想辦法?！?
