1、DSP發(fā)展、現況及其應用中英文翻譯 外文文獻翻譯 中英文對照數字信號處理（Digital Signal Processing，簡稱DSP）是一門涉及許多學科而又廣泛應用于許多領域的新興學科。DSP有兩種含義：digital Signal Processing（數字信號處理）、Digital Signal Processor（數字信號處理器）。我們常說的DSP指的是數字信號處理器。數字信號處理器是一種適合完成數字信號處理運算的處理器。20世紀60年代以來，隨著計算機和信息技術的飛速發(fā)展，數字信號處理技術應運而生并得到迅速的發(fā)展。在過去的二十多年時間里，數字信號處理已經在通信等領域得到極為廣泛的應
2、用。數字信號處理是利用計算機或專用處理設備，以數字形式對信號進行采集、變換、濾波、估值、增強、壓縮、識別等處理，以得到符合人們需要的信號形式。數字信號處理是以眾多學科為理論基礎的，它所涉及的范圍極其廣泛。例如，在數學領域，微積分、概率統(tǒng)計、隨機過程、數值分析等都是數字信號處理的基本工具，與網絡理論、信號與系統(tǒng)、控制論、通信理論、故障診斷等也密切相關。近來新興的一些學科，如人工智能、模式識別、神經網絡等，都與數字信號處理密不可分?？梢哉f，數字信號處理是把許多經典的理論體系作為自己的理論基礎，同時又使自己成為一系列新興學科的理論基礎。DSP主要應用在數字信號處理中，目的是為了能夠滿足實時信號處理的
3、要求，因此需要將數字信號處理中的常用運算執(zhí)行的盡可能快，這就決定了DSP的特點和關鍵技術。適合數字信號處理的關鍵技術：DSP包含乘法器、累加器、特殊地址發(fā)生器、領開銷循環(huán)等；提高處理速度的關鍵技術：流水線技術、并行處理技術、超常指令（VLIW）、超標量技術、DMA等。從廣義上講，DSP、微處理器和微控制器（單片機）等都屬于處理器，可以說DSP是一種CPU。DSP和一般的CPU又不同，最大的區(qū)別在于：CPU是馮.諾伊曼結構的；DSP是數據和地址空間分開的哈佛結構。世界上第一個單片DSP芯片應當是1978年AMI公司發(fā)布的S2811，1979年美國Intel公司發(fā)布的商用可編程器件2920是DSP
4、芯片的一個主要里程碑。這兩種芯片內部都沒有現代DSP芯片所必須有的單周期乘法器。1980 年，日本 NEC 公司推出的PD7720是第一個具有乘法器的商用DSP 芯片。在這之后，最成功的DSP 芯片當數美國德州儀器公司（Texas Instruments，簡稱TI）的一系列產品。TI 公司在1982年成功推出其第一代DSP 芯片 TMS32010及其系列產品TMS32011、TMS320C10/C14/C15/C16/C17等，之后相繼推出了第二代DSP芯片TMS32020、TMS320C25/C26/C28，第三代DSP芯片TMS320C30/C31/C32，第四代DSP芯片TMS320C4
5、0/C44，第五代 DSP 芯片TMS320C5X/C54X，第二代DSP芯片的改進型TMS320C2XX，集多片DSP芯片于一體的高性能DSP芯片TMS320C8X以及目前速度最快的第六代DSP芯片TMS320C62X/C67X等。TI將常用的DSP芯片歸納為三大系列，即：TMS320C2000系列（包括TMS320C2X/C2XX）、TMS320C5000系列（包括TMS320C5X/C54X）、TMS320C6000系列（TMS320C62X/C67X）。如今，TI公司的一系列DSP產品已經成為當今世界上最有影響的DSP芯片。TI公司也成為世界上最大的DSP芯片供應商，其DSP市場份額占
6、全世界份額近50。目前，DSP處理器仍被TI、AGERE、ADI等公司占領，產品受外國大企業(yè)控制。國內發(fā)展DSP的廠商并不多，而主要的應用是DVD與無線電話等產品，因此國內DSP的產值并不高。而在產品應用上，目前重要的DSP應用產品，如移動電話、調制解調器等個人計算機與通訊領域應用產品，都是采用國際大廠的DSP 解決方案。DSP技術應用到我們生活的每一個角落，從軍用到民用，從航空航天到生產生活，都越來越多地使用DSP。DSP技術在航空航天方面，主要用于雷達和聲納信號處理；在通信方面，主要用于移動電話、IP電話(voice over IP)、ADSL和HFC的信號傳輸；在控制方面，主要用于電機控
7、制、光驅和硬盤驅動器；在測試/測量方面，主要用于虛擬儀器、自動測試系統(tǒng)、醫(yī)療診斷等；在電子娛樂方面，主要用于高清晰度電視(HDTV)、機頂盒(STB)、AC-3、家庭影院、DVD等應用；還有數字相機、網絡相機等等都應用了DSP技術。同時，SOC芯片系統(tǒng)、無線應用、嵌入式DSP都是未來DSP的發(fā)展方向和趨勢。可以說，沒有DSP就沒有對互聯(lián)網的訪問，也不會有多媒體，也沒有無線通信。因此，DSP仍將是整個半導體工業(yè)的技術驅動力。現在，DSP應用領域不斷拓寬，其函蓋面包括寬帶Internet接入業(yè)務、下一代無線通信系統(tǒng)的發(fā)展、數字消費電子市場、汽車電子市場的發(fā)展等諸多多方面?，F代數字信號處理器是執(zhí)行高
8、速數字信號處理的IC電路、它恰好適應多媒體信息化社會需求，迅速發(fā)展壯大。如今，世界電子器件市上，各種各樣的DSP器件已相當豐富。大大小小封裝形式的DSP器件，已廣泛應用于各種產品的生產領域，而且DSP的用領域仍在不斷地擴大，發(fā)展速度異常。主要應用有數字化移動電話、數據調制解調器、磁盤光盤控制器需求、圖形圖像處理需求、汽車電子系統(tǒng)等。應用DSP的領域可以說是不勝枚舉，電視會議系統(tǒng)里，也大量應用DSP器件。視聽機器里也都應用DSP。隨著科學技術的發(fā)展，將會出現許許多多的DSP新應用領域。DSP的開發(fā)工具包括各種仿真軟件、調試軟件、硬件仿真器、評估板、初學者實驗套件、教學套件等。國外有一些DSP的咨
9、詢公司及網站，他們起到DSP用戶和DSP芯片供應商、DSP第三方之間的橋梁作用，也會為客戶提供設計、提供軟件和硬件及出版資料圖書，有些還辦培訓班。國內也有不少DSP論壇，以便用戶之間進行DSP技術的交流。中國DSP市場增長迅速，在DSP應用方面中國一直保持著與國際上DSP技術同步的態(tài)勢，從DSP芯片面世開始，中國就有單位應用、銷售DSP芯片。隨著中國社會數字化、信息化的進展和中國經濟的持續(xù)穩(wěn)定增長，刺激了電子信息產業(yè)和市場的快速發(fā)展，推動了DSP的廣泛應用。DSP Development, the Status and Its ApplicationDigital signal process

We often say that what DSP refers to the digital signal processor. The Digital Signal Processors are suitable for to
11、complete digital signal processing operation of the processor. Since the 1960s, with the computer and the information technologys swift development, the digital signal processing technologies has arisen at the historic moment and obtains the rapid development. In the past more than 20 years, the dig

Recently the emerging some disciplines, like the artificial intelligence, the pattern recognition, the ne

It can be said that digital signal processing takes many classics system infos own rationale, simultaneously causes itself to become a services if emerging disciplines the rationale. The DSP is mainly applied in the digital

18、peaking, DSP, microprocessor and microcontroller (MCU) belong to the processor, can be said that DSP is a kind of CPU. DSP and general CPU are also different, the biggest difference lies in: CPU is Von Norma structure; while DSP its the data and the address space separated Harvard structure. The com

These two kinds of chip interior does not have the monocycle multiplier which the modern DSP
20、chip must have. In 1980, Japans NEC Corp. launched PD7720 is the first of a multiplier of commercial DSP chips.After this, the most successful DSP chip works as the number US Texas Instruments Company (TI)a series of products. TI corporation succeeded in 1982 promotes its first generation of DSP chi

TI the commonly used DSP chip induction will be three big series, namely
23、: MS320C2000 series (including TMS320C2X/2XX), TMS320C5000 series (including TMS320C5X/C54X), TMS320C6000 series (TMS320C62X/C67X). Now, TI Corporations a series of DSP chip product already became none in the world the most influence DSP chip. TI Corporation also becomes the biggest DSP chip supplie
24、r and its DSP market chare occupies the world share nearly 50%.At present, the DSP processor by TI,AGERE, ADI and so on was still seized, the product is controlled the foreign big enterprise. At home the DSP manufactures are not many, but the main application product is DVD and the radio telephone a
25、nd so on. Therefore the domestic DSP output value is not high. But in the product application, the important DSP application product, like the mobile phone, the modem, personal computer and the communication domain application products all use the international big plant DSP solution.The DSP technol
26、ogy applies corner of our life, from military to civil, the aerospace to the production life.In the aerospace aspect, the DSP technology mainly used in the radar and sonar signal disposals. In the correspondence aspect, mainly used in the mobile phone, Voice Over IP, ADSL and HFC signaling; In the c
27、ontrol aspect, mainly used in the motor control, the light driving with the hard disk driver; In the test/survey aspect, mainly uses in the hypothesized instrument tm the automated test system, the medical diagnosis and so on; In the electronic entertainment aspect, mainly used in applications high-
28、definition television (HDTV), set-top boxes (STB), AC - 3, family theater, DVD ;Also the digital camera ,the network camera and so on to apply the DSP technology. At the same time, the SOC chip system, will apply, embedded DSP is wireless the future DSP development direction and the tendency, It can
29、 be said if these the DSP there will be few people to browse internet multimedia, also will not have the wireless communication. Therefore, the DSP will still be the entire semiconductor industry technical driving influence. Now, the DSP applications application domain expands unceasingly, its lette

The modern digital signal processor is caries out the high speed figure signal process
31、ing IC electric circuit, it to adapt the multimedia informanization society demand exactly, grows strong rapidly. Now, world applied in each product realm of production, moreover DSP unceasingly was still expanding with the domain, the development speed is unusual.The main applications of it is the
32、digitization mobile phone, the data modem, the disk / CD-ROM controller demand, the graph imagery processing demand, the automobile electron system and so on.The using of the DSP domain is too numerous to cite individually. In the TV conference system, use applies the DSP component massively. In the
33、 seeing and hearing machine also applies the DSP. Along with science and technology development, it will present many the DSP new application domains.The DSP development kit includes each kind of simulation software, the hardware simulator, the appraisal board, the beginner to test the suite, the te
34、aching suite and so on. Overseas has some DSP Consultant firm and the website, they have the DSP user and the DSP chip supplier, between the DSP third party bridge role, also will provide the design for the customer, to provide the software and the hardware and the publication material books, some w
35、ill also have the training class. At home there are many DSP forums, so that the user can carry on the DSP technology to the exchange information.With the rapid growth of Chinas DSP market, the DSP application in China has been maintaining the same technology synchronization situation internationally. Along with the Chinese society digitization, the informationization progress continued with the Chinese economy to grown stably has stimulated the fast development of market and the electronic information industry and promoted the DSP widespread application. .此處忽略！
