1 計(jì)算機(jī)體系的發(fā)展歷程
??? 隨著計(jì)算技術(shù)的發(fā)展,，計(jì)算機(jī)體系也在不斷發(fā)展變化,。20世紀(jì)60年代初期,，隨著晶體管和磁芯存儲(chǔ)器的出現(xiàn)，處理單元和存儲(chǔ)器實(shí)現(xiàn)小型化,，并行計(jì)算機(jī)開(kāi)始出現(xiàn),。到了20世紀(jì)60年代末期，單一處理器中可以集成多個(gè)功能單元,，產(chǎn)生了流水線技術(shù),。該技術(shù)與單純提高CPU時(shí)鐘頻率相比，大大提高了并行計(jì)算機(jī)系統(tǒng)的性能,。
??? 當(dāng)時(shí),，伊利諾依大學(xué)和Burroughs公司開(kāi)始著手實(shí)施Illiac Ⅳ計(jì)劃，研制1臺(tái)64顆CPU的SIMD主機(jī)系統(tǒng),，涉及到相關(guān)硬件技術(shù),、體系結(jié)構(gòu)、I/O設(shè)備,、操作系統(tǒng),、程序設(shè)計(jì)語(yǔ)言，以及包括應(yīng)用程序在內(nèi)的眾多研究課題,。1975年,，隨著一臺(tái)規(guī)模大大縮小的原型系統(tǒng)(僅使用了16顆CPU)的面世，新的計(jì)算技術(shù)也得到了發(fā)展,。
??? 首先是存儲(chǔ)系統(tǒng)的概念,，提出了虛擬存儲(chǔ)和緩存的思想，大大提高了計(jì)算機(jī)的整體性能,。其次是半導(dǎo)體存儲(chǔ)器開(kāi)始代替磁芯存儲(chǔ)器,，大大縮小了存儲(chǔ)器的體積并提高了訪存速度。集成電路技術(shù)也被廣泛而迅速地應(yīng)用到計(jì)算機(jī)技術(shù)中,。
??? 1976年Cray-1問(wèn)世,，向量計(jì)算技術(shù)被應(yīng)用到高性能計(jì)算機(jī)中。Cray-1對(duì)所使用的邏輯電路是經(jīng)過(guò)精心設(shè)計(jì)的,，采用RISC精簡(jiǎn)指令集,，引入向量寄存器，完成向量運(yùn)算,。
??? 20世紀(jì)80年代開(kāi)始,，微處理器技術(shù)高速發(fā)展。此時(shí),，微處理器隨著機(jī)器的字長(zhǎng)從4位,、8位、16位一直增加到32位、64位,，其性能也隨之顯著提高,。卡內(nèi)基·梅隆大學(xué)提出共享存儲(chǔ)多處理器體系結(jié)構(gòu),，并在當(dāng)時(shí)流行的DEC PDP-11小型計(jì)算機(jī)的基礎(chǔ)上研制出1臺(tái)由16臺(tái)PDP-11/40處理機(jī)通過(guò)交叉開(kāi)關(guān)與16個(gè)共享存儲(chǔ)器模塊相連接而成的共享存儲(chǔ)多處理器系統(tǒng)C.mmp,。伯克利加州大學(xué)對(duì)基于SMP方式的總線協(xié)議進(jìn)行擴(kuò)展，提出了Cache一致性問(wèn)題的處理方案,。從此,，C.mmp開(kāi)創(chuàng)出的共享存儲(chǔ)多處理器體系結(jié)構(gòu)便成為服務(wù)器和桌面工作站的主流。
??? 20世紀(jì)80年代中期,，基于消息傳遞機(jī)制的并行計(jì)算機(jī)開(kāi)始出現(xiàn),，加州理工學(xué)院將64個(gè)i8086/i8087處理器通過(guò)超立方體互連結(jié)構(gòu)連接起來(lái)。此后,，便先后出現(xiàn)了Intel iPSC系列,、INMOS Transputer系列、Intel Paragon,，以及IBM SP的前身Vulcan等基于消息傳遞機(jī)制的并行計(jì)算機(jī),。
??? 20世紀(jì)80年代末到20世紀(jì)90年代初，共享存儲(chǔ)器方式的大規(guī)模并行計(jì)算機(jī)又獲得了新的發(fā)展,。IBM將大量早期的RISC微處理器通過(guò)蝶形互聯(lián)網(wǎng)絡(luò)連接起來(lái),。斯坦福大學(xué)提出DASH計(jì)劃，通過(guò)維護(hù)1個(gè)保存有每一緩存塊位置信息的目錄結(jié)構(gòu)來(lái)實(shí)現(xiàn)分布式共享存儲(chǔ)器的緩存一致性技術(shù),，IEEE在此基礎(chǔ)上提出了緩存一致性協(xié)議的標(biāo)準(zhǔn),。從20世紀(jì)90年代末開(kāi)始，以前發(fā)展的主要幾種體系逐步走向融合,，同時(shí)隨著新技術(shù)的出現(xiàn)又為新的架構(gòu)帶來(lái)了新的革命,。
2 Cell和多核等新型處理器結(jié)構(gòu)帶來(lái)新的方向
??? 隨著人們對(duì)計(jì)算機(jī)CPU速度的不斷追求和微電子技術(shù)的發(fā)展及限制，一種新的處理器結(jié)構(gòu)開(kāi)始出現(xiàn),，它就是Cell和多核架構(gòu)技術(shù)的實(shí)現(xiàn),。
??? Cell架構(gòu)是1個(gè)單芯片多核處理單元，處理單元之間共享存儲(chǔ)器資源,。與多核處理器不同,，Cell主要采用協(xié)處理器方式，然后依靠多個(gè)處理器并行技術(shù)來(lái)實(shí)現(xiàn)運(yùn)算速度的提高,。盡管存在應(yīng)用程序難以充分利用的弊病，但是其綜合效率以及功耗控制都非常理想,，開(kāi)創(chuàng)了完全可擴(kuò)展的架構(gòu)模式,。從而為大型機(jī)、服務(wù)器,、以至包括手機(jī)在內(nèi)的所有消費(fèi)類(lèi)電子產(chǎn)品提供1個(gè)統(tǒng)一的架構(gòu)平臺(tái),。只需要改變頻率,、內(nèi)核數(shù)量等相關(guān)參數(shù)，即可保證在1個(gè)機(jī)器上開(kāi)發(fā),、在所有機(jī)器上運(yùn)行,，大大節(jié)省了軟件移植所帶來(lái)的費(fèi)用。因此,，使用Cell的手機(jī)完全可以與相應(yīng)的服務(wù)器進(jìn)行直接溝通和資源共享,，從而把這些小資源集合成為一個(gè)龐大的計(jì)算資源，構(gòu)成一個(gè)真正的信息化時(shí)代,。在這個(gè)資源體系中,，每個(gè)資源節(jié)點(diǎn)可能是微不足道的，但是每個(gè)節(jié)點(diǎn)的運(yùn)算都可能被整個(gè)資源庫(kù)無(wú)窮放大,，從而構(gòu)成一個(gè)完整的Cell網(wǎng)絡(luò),，為消費(fèi)類(lèi)電子的信息網(wǎng)絡(luò)化帶來(lái)真正的革命。
??? 多核處理器的出現(xiàn)則是一場(chǎng)新的計(jì)算方式的革命[1,，2],。2006 年，處理器開(kāi)始從單核向多核處理器發(fā)展,，多核處理器已不再局限于高端服務(wù)器,，開(kāi)始向 PC機(jī)普及，多核處理器使 PC 機(jī)變成并行式計(jì)算機(jī),。在多核處理器逐漸成為市場(chǎng)主導(dǎo)后,，怎樣利用多核的優(yōu)勢(shì)來(lái)優(yōu)化并行程序設(shè)計(jì)成為一個(gè)需要研究和解決的問(wèn)題。多核設(shè)計(jì)的出現(xiàn)為摩爾定律轉(zhuǎn)向基辛格規(guī)則帶來(lái)了生命力,。英特爾推出了雙核,、四核至強(qiáng)和雙核安騰處理器，AMD也推出了雙核,、四核皓龍芯片,，IBM的Power5+芯片也是雙核設(shè)計(jì)，針對(duì)HPC和圖形運(yùn)算的Cell芯片更是擁有1+8個(gè)核,，SUN公司的Ultrasparc T1擁有8個(gè)核,，Clearspeed(96核)、思科NPU（192核）,、RIKEN（512核）更是推出了擁有數(shù)十個(gè)甚至數(shù)百個(gè)核的芯片,，預(yù)計(jì)到2020年，千核CPU也會(huì)誕生,。同時(shí),，多核技術(shù)在高性能計(jì)算中也已獲得了廣泛應(yīng)用。

3可重構(gòu)計(jì)算技術(shù)帶來(lái)新的亮點(diǎn)
??? 以前的計(jì)算機(jī)硬件技術(shù)都是固件化的，無(wú)法隨著環(huán)境的改變而改變,，產(chǎn)生大量的電子垃圾,，不利于環(huán)保經(jīng)濟(jì)的發(fā)展，而可重構(gòu)計(jì)算技術(shù)的出現(xiàn)則為我們帶來(lái)了曙光,?？芍貥?gòu)計(jì)算就是通過(guò)實(shí)現(xiàn)硬件的可編程技術(shù)來(lái)滿足不同計(jì)算任務(wù)的需求，從而達(dá)到最佳性能,，且要求這種硬件結(jié)構(gòu)的變化能實(shí)時(shí)地適應(yīng)計(jì)算任務(wù)要求的變化,。這種體系結(jié)構(gòu)可變的特點(diǎn)，可以滿足實(shí)際應(yīng)用中的多元化需求,。實(shí)現(xiàn)可重構(gòu)計(jì)算的底層技術(shù)有FPGA（現(xiàn)場(chǎng)可編程門(mén)陣列）和CPLD編程技術(shù),。
??? 在處理器芯片體系結(jié)構(gòu)設(shè)計(jì)中采用可重構(gòu)計(jì)算技術(shù)的基本思想是通過(guò)動(dòng)態(tài)配置片上大量的處理單元、存儲(chǔ)單元和互連單元,，來(lái)支持各種不同類(lèi)型并行性的計(jì)算模型,，從而能在一個(gè)很寬的應(yīng)用范圍內(nèi)達(dá)到高性能，提高片上硬件資源的利用率,?；诳芍貥?gòu)計(jì)算技術(shù)實(shí)現(xiàn)的多型微處理芯片體系結(jié)構(gòu)能夠很好地利用半導(dǎo)體技術(shù)發(fā)展提供的能力，在解決應(yīng)用的多樣性問(wèn)題的同時(shí),，還可解決片上資源利用率,、設(shè)計(jì)復(fù)雜性、系統(tǒng)可靠性以及降低成本和功耗等多方面的問(wèn)題,?？芍貥?gòu)計(jì)算技術(shù)在處理器芯片設(shè)計(jì)中的應(yīng)用改變了傳統(tǒng)的指令集體系結(jié)構(gòu)、微體系結(jié)構(gòu)設(shè)計(jì)和實(shí)現(xiàn)技術(shù),。
??? 可重構(gòu)計(jì)算技術(shù)[3-5]使計(jì)算機(jī)硬件的設(shè)計(jì)不再?gòu)?fù)雜,，硬件不再只是“硬”，也具備“軟”的特性,，即硬件可“編程”,。在可編程的介質(zhì)中提供強(qiáng)大的計(jì)算能力和密度，使得在單片系統(tǒng)上以低硬件復(fù)雜度開(kāi)發(fā)出各種類(lèi)型的應(yīng)用, 同時(shí)能夠針對(duì)應(yīng)用中固有的并行性特征動(dòng)態(tài)配置多個(gè)微體系結(jié)構(gòu)模型,，從而大幅度提高計(jì)算系統(tǒng)性能,、降低功耗和設(shè)計(jì)的復(fù)雜性。
??? 在設(shè)計(jì)中通常采用“自頂向下”的方法,，即把系統(tǒng)分為若干模塊,。原則是使得每個(gè)模塊有較獨(dú)立的功能，模塊之間的耦合盡可能?。ㄍǔ１憩F(xiàn)為相互通信盡量簡(jiǎn)單）,。劃分之后,，再分別實(shí)現(xiàn)每個(gè)模塊,，最后把模塊像搭積木似地組裝起來(lái),。其中某些模塊可以做成現(xiàn)成的，可供設(shè)計(jì)時(shí)使用,，即IP核心,，它可以重復(fù)使用，從而提高了設(shè)計(jì)效率,。再配合成熟的EDA工具作為設(shè)計(jì)流程的工具鏈,，這樣設(shè)計(jì)就顯得相對(duì)容易。當(dāng)然相對(duì)使用高級(jí)語(yǔ)言的軟件編程,，仍然是難于設(shè)計(jì)和缺乏靈活性的,，其實(shí)IP的思想與軟件的靜態(tài)鏈接庫(kù)很相似?？梢园袸P核心封裝成軟件可調(diào)用的庫(kù)的形式,。庫(kù)分為靜態(tài)庫(kù)和動(dòng)態(tài)庫(kù)，動(dòng)態(tài)庫(kù)允許在程序執(zhí)行時(shí)按需加載和卸載,。這相當(dāng)于硬件在設(shè)計(jì)運(yùn)行時(shí),，IP核心可以動(dòng)態(tài)地載入和卸出，當(dāng)然前提是并不破壞原有程序和數(shù)據(jù),。把IP核心封裝成動(dòng)態(tài)庫(kù),，將是可重構(gòu)計(jì)算平臺(tái)最為核心的思想。
??? 隨著芯片設(shè)計(jì)技術(shù)的SoC化,，如何在1個(gè)芯片中集成很多現(xiàn)有的IP核,，快速設(shè)計(jì)系統(tǒng)成為未來(lái)研究發(fā)展的重點(diǎn)。這時(shí),，IP核的可重用性和可更改性就成了最關(guān)鍵的技術(shù),，而開(kāi)放源碼的IP核將提供方向。中國(guó)有案可查的開(kāi)放源碼硬件項(xiàng)目是2001年3月啟動(dòng)的OpenARM項(xiàng)目,，在“中國(guó)芯”盛行的那幾年里,，不少學(xué)校和研究單位參考開(kāi)放源碼的處理器設(shè)計(jì)了自己的微處理器。這個(gè)時(shí)期,，中國(guó)利用開(kāi)放源碼硬件的資源進(jìn)行IC設(shè)計(jì)的方法開(kāi)始悄然流行,。中國(guó)工程院院士許居衍的論文《半導(dǎo)體特征循環(huán)與可重構(gòu)芯片》中基于此技術(shù)的發(fā)展提出 “許氏循環(huán)”[3]，半導(dǎo)體產(chǎn)品的主要特征將沿著“通用”與“專(zhuān)用”循環(huán)波動(dòng),，每10年1次,，從2018年～2028年，將會(huì)重新走向通用,?！霸S氏循環(huán)”發(fā)展圖如圖2所示,。
?
??? 許居衍的依據(jù)是,，因?yàn)椤翱芍貥?gòu)計(jì)算是1個(gè)難度頗大,、涉及面甚廣的課題，盡管當(dāng)前很多人在研究,，但是無(wú)論在器件結(jié)構(gòu),、系統(tǒng)結(jié)構(gòu)還是在設(shè)計(jì)方法學(xué)方面，均存在不少問(wèn)題,，仍有很長(zhǎng)的路要走,。可重構(gòu)計(jì)算技術(shù)的發(fā)展,，最終將推動(dòng)主流應(yīng)用進(jìn)入U(xiǎn)-SoC通用波動(dòng),。只通過(guò)對(duì)‘毛坯芯片’(Raw Chip)的配置編程就可以得到用戶自定義的功能電路，從而引導(dǎo)半導(dǎo)體產(chǎn)業(yè)結(jié)構(gòu)演變,，最終促進(jìn)芯片應(yīng)用創(chuàng)新Designless 模式的興起”,。所謂的Designless，就是無(wú)需設(shè)計(jì),、自動(dòng)生成集成電路,，工程師只需要關(guān)注應(yīng)用和功能層面即可。但實(shí)現(xiàn)Disignless的前提是必須軟硬件都開(kāi)放,。因?yàn)槿绻婚_(kāi)放軟件,，不知硬件細(xì)節(jié)，還是無(wú)法生成一個(gè)完整設(shè)計(jì),。因此,，一個(gè)邏輯的發(fā)展應(yīng)是“硬”、“軟”均可編程,，即算法可編程,、可重構(gòu)器件也可編程的U-SoC。
4 可重構(gòu)技術(shù)與多核技術(shù)的融合
??? 自從計(jì)算機(jī)發(fā)明以來(lái),，馮·諾依曼體系結(jié)構(gòu)一直占據(jù)計(jì)算機(jī)體系結(jié)構(gòu)的統(tǒng)治地位,，科學(xué)家和工程師們?cè)诖嘶A(chǔ)上不斷研究硬件和軟件，使CPU和存儲(chǔ)器技術(shù)得到了飛速的發(fā)展,，也為信息化,、網(wǎng)絡(luò)化奠定了基礎(chǔ)。隨著人們對(duì)信息化的要求越來(lái)越高,，馮·諾依曼體系結(jié)構(gòu)已經(jīng)無(wú)法滿足人們的技術(shù)需求和發(fā)展要求,，對(duì)計(jì)算機(jī)的要求不再僅僅是高速計(jì)算，同時(shí)更應(yīng)具備信息處理和智能升級(jí)能力,?？芍貥?gòu)技術(shù)與多核技術(shù)的出現(xiàn)為此提供了基礎(chǔ),。筆者認(rèn)為新的計(jì)算機(jī)體系結(jié)構(gòu)將是：(1)CPU將不再由1個(gè)核組成，而是由多個(gè)核組成的Cell,；(2)存儲(chǔ)器將不是中心,，取而代之的將是信息通路；(3)計(jì)算機(jī)不再是五大部件,，而是由多個(gè)信息處理節(jié)點(diǎn)構(gòu)成,，每個(gè)節(jié)點(diǎn)的智能化[5]和集成化越來(lái)越高,；(4)程序設(shè)計(jì)將包括軟件和硬件設(shè)計(jì),，生產(chǎn)商們提供的產(chǎn)品將是一個(gè)個(gè)封裝好的中間件，作為應(yīng)用者將勿需關(guān)心程序設(shè)計(jì),，只需要關(guān)注專(zhuān)業(yè)設(shè)計(jì),，對(duì)于應(yīng)用者將會(huì)更加友好。新的計(jì)算機(jī)體系結(jié)構(gòu)如圖3所示,。
