Unit 9 数字信号和信号处理Unit 9-1第一部分：数字信号处理数字信号处理（DSP）是研究数字表示的信号以及这些信号的处理方法。

数字信号处理和模拟信号处理是信号处理的子领域。

数字信号处理包括音频及语音信号处理、声纳和雷达信号处理、传感器阵列处理、谱估计、统计信号处理、图像处理、通信信号处理、生物医学信号处理等子领域。

数字信号处理的目标通常是测量连续的真实世界的模拟信号或对其滤波，因此，第一步常常是使用模数转换器将信号从模拟形式转换成数字形式。

通常，要求的输出信号为另一个模拟输出信号，这就需要数模转换器。

数字信号处理的算法有时通过使用专用计算机来实现，它们（专用计算机）利用被称为数字信号处理器的专用微处理器（简称DSP）。

这些数字信号处理器实时处理信号，通常是针对具体目的而设计的专用集成电路（ASIC）。

当灵活性和快速开发比大批量生产的成本更重要时，DSP算法也可以用现场可编程门阵列来实现。

数字信号处理域在数字信号处理中，工程师通常在下面几个域的一个域中来研究数字信号：时域（一维信号），空域（多维信号），频域，自相关域以及小波域。

他们按照某些依据来猜测（或试验不同的可能性）那一个域能够最好地表示信号的本质特性来选择在其中进行信号处理的域。

从测量设备得到的样本序列产生（信号的）时域或空域表示，而离散Fourier变换则产生频域表示即频谱。

自相关定义为信号与其自身经过时间或空间间隔变化后的互相关。

信号采样随着计算机应用的增长，数字信号处理的使用和需求日益增多。

为了能够在计算机上使用模拟信号，必须使用模数转换器（ADC）对其进行数字化。

采样通常分两步实现：离散化和量化。

在离散化阶段，信号空间被分割为相等的区间，用相应区间的代表性信号值代替信号本身。

在量化阶段，用有限集中的值来近似代表性的信号值。

为了能够正确地重建被采样的模拟信号，必须满足奈奎斯特-香农采样定理。

定理规定：采样频率必须大于两倍的信号带宽。

Basic Signal Source Applications
stress/margin test
• Stressing Communication Receivers
Engineers working with serial data stream architectures (commonly used in digital communications buses and disk drive amplifiers) need to stress their devices with impairments, particularly jitter and timing violations. Advanced signal sources save the engineer untold hours of calculation by providing efficient built-in jitter editing and generation tools. These instruments can shift critical signal edges as little as 0.3 ps.

Unit 1 电子学：模拟和数字Unit 1-1第一部分：理想运算放大器和实际限制为了讨论运算放大器的理想参数，我们必须首先定义一些指标项，然后对这些指标项讲述我们所认为的理想值。

第一眼看运算放大器的性能指标表，感觉好像列出了大量的数值，有些是陌生的单位，有些是相关的，经常使那些对运放不熟悉的人感到迷惑。

对于这种情况我们的方法是花上必要的时间有系统的按照列出的次序阅读并理解每一个定义。

如果没有对每一项性能指标有一个真正的评价，设计人员必将失败。

目标是能够依据公布的数据设计电路，并确认构建的样机将具有预计的功能。

对于线性电路而言，它们与现在的复杂逻辑电路结构相比看起来较为简单，（因而在设计中）太容易忽视具体的性能参数了，而这些参数可极大地削弱预期性能。

现在让我们来看一个简单但很引人注意的例子。

考虑对于一个在50kHz频率上电压增益为10的放大器驱动10kΩ负载时的要求。

选择一个普通的带有内部频率补偿的低价运放，它在闭环增益为10时具有所要求的带宽，并且看起来满足了价格要求。

器件连接后，发现有正确地增益。

但是它只能产生几伏的电压变化范围，然而数据却清楚地显示输出应该能驱动达到电源电压范围以内2到3伏。

设计人员忽视了最大输出电压变化范围是受频率严格限制的，而且最大低频输出变化范围大约在10 kHz受到限制。

当然，事实上这个信息也在数据表上，但是它的实用性并没有受到重视。

这种问题经常发生在那些缺乏经验的设计人员身上。

所以这个例子的寓意十分明显：在开始设计之前总要花上必要的时间来描写全部的工作要求。

关注性能指标的详情总是有益的。

建议下面列出的具体的性能指标应该考虑：1. 在温度，时间和供给电压下的闭环增益的精确性和稳定性2. 电源要求，电源和负载阻抗，功率消耗3. 输入误差电压和偏置电流，输入输出电阻，随着时间和温度的漂移4. 频率响应，相位偏移，输出变化范围，瞬态响应，电压转换速率，频率稳定性，电容性负载驱动，过载恢复5. 线性，失真和噪声6. 输入，输出或电源保护要求，输入电压范围，共模抑制7. 外部补偿调整要求不是所有的指标项都是有关的，但要记住最初就考虑它们会更好，而不要被迫返工。

Unit3 computer architecture and microprocessors3--1 Computer Architecture1) Computer architecture , in computer science , is a general term referring to the structure of all or part of computer system . The term also covers the design of system software , such as the operating system (the program that controls the computer) , as well as referring to the combination of hardware and basic software that links the machines on a computer network . Computer architecture refers to an entire structure and to the details needed to make it functional . Thus , computer architecture covers computer systems , microprocessors , circuits , and system programs . Typically the term does not refer to application programs , such as spreadsheets or word processing , which are required to perform a task but not to make the system run .2)1.Design Elements3) In designing a computer system , architects consider five major elements that make up the system's hardware : the arithmetic /logic unit , control unit , memory , input , and output . The arithmetic /logic unit performs arithmetic and compares numerical values . The control unit directs the operation of the computer by taking the user instructions andtransforming them into electrical signals that the computer 's circuitry can understand . The combination of the arithmetic /logic unit and the control unit is called the central processing unit (CPU) . The memory stores instructions and data . The input input and output sections allow the computer to receive and send data , respectively .4) Different hardware architectures are required because of the specialized needs of systems and users . One user may need a system to display graphics extremely fast , while another system may have to be optimized for searching a database or conserving battery power in a laptop computer .5) In addition to the hardware design , the architects must consider what software programs will operate the system . Software , such as programming languages and operating systems , makes the details of the hardware architecture invisible to the user . For example , computers that use the C programming language or a UNIT operating system may appear the same from the user's viewpoint , although they use different hardware architectures .6)2.Processing Architecture7) When a computer carries out an instruction , it proceeds through five steps . First ,the control unit retrieves theinstruction from memory , for example , an instruction to add two numbers . Second , the control unit decodes the instruction into electronic signals that control the computer . Third , the control unit fetches the data (the two numbers) . Fourth , the arithmetic/logic unit performs the specific operation ( the addition of the two numbers ) . Fifth , the control unit saves the result ( the sum of the two numbers ) .8) Early computers used only simple instructions because the cost of electronic capable of carrying out complex instructions was high . As this cost decreased in the 1960s , more complicated instructions became possible . Complex instructions ( single instructions that specify multiple operations ) can save time because they make it unnecessary for the computer to retrieve additional instructions . For example , if seven operations are combined in one instruction , then six of the steps that fetch instructions are eliminated and the computer spends less time processing that operation . Computers that combine several instructions into a single operation are called complex instruction set computers ( CISC ) .9) However , most programs do not often use complexinstructions , but consist mostly of simple instructions . When these simple instructions are run on CISC architectures , they slow down processing because each instruction--whether simple or complex --takes longer to decode in a CISC design . An alternative strategy is to return to designs that use only simple , single--operation instruction sets and make the most frequently used operations faster in order to increase overall performance . Computers that follow this design are called reduced instruction set computers ( RISC ) .10) RISC designs are especially fast at the numerical computations required in science , graphics , and engineering applications . CISC designs are commonly used for non-numerical computations because they provide special instruction sets for handling character data , such as text in a word processing program . Specialized CISC architectures , called digital signal processors , exist to accelerate processing of digitized audio and video signals .11)3.Open and Closed Architectures12) The CPU of a computer is connected to memory and to the outside world by means of either an open or a closed architecture . An open architecture can be expanded after the system has been built , usually by adding extra circuitry ,such as a new microprocessor computer chip connected to the main system . The specifications of the circuitry are made public , allowing other companies to manufacture these expansion products .13) Closed architectures are usually employed in specialized computers that will not require expansion , for example , computers that control microwave ovens . Some computer manufacturers have used closed architectures so that their customers can purchase expansion circuitry only from them . This allows the manufacture to charge more and reduces the options for the consumer .14)work Architecture15) Computers communicate with other computers via networks . The simplest network is a direct connection between two computers . However , computers can also be connected over large networks , allowing users to exchange data , communicate via electronic mail , and share resources such as printers .16) Computers can be connected in several ways . In a ring configuration , data are transmitted along the ring and each computer in the ring examines this data to determine if it is the intended recipient . If the data are not intended fora particular computer , the computer passes the data to the next computer in the ring . This process is repeated until the data arrive at their intended destination . A ring network allows multiple messages to be carried simultaneously , but since each message is checked by each computer , data transmission is slowed .17) In a bus configuration , computers are connected througha single set of wires , called a bus . One computer sends data to another by broadcasting the address of the receive and the data over the bus . All the computers in the network look at the address simultaneously , and the intended recipient accepts the data . A bus network , unlike a ring network , allows data to be sent directly from one computer to another . However , only one computer at a time can transmit data . The others must wait to send their messages .18) In a star configuration , computers are linked to a central computer called a hub . A computer sends the address of the receiver and the data to the hub , which then links the sending and receiving computers directly . A star network allows multiple messages to be sent simultaneously , but it is more costly because it uses an additional computer , the hub , to direct the data .19)5.Recent Advances20) One problem in computer architecture is caused by the difference between the speed of the CPU and the speed at which memory supplies instructions and data . Modern CPUs can process instructions in 3 nanoseconds ( 3 billionths of a second ) . A typical memory access , however , takes 100 nanoseconds and each instruction may require multiple accesses . To compensate for this disparity , new computer chips have been designed that contain small memories , called caches , located near the CPU . Because of their proximity to the CPU and their small size , caches can supply instructions and data faster than normal memory . Cache memory stores the most frequently used instructions and data and can greatly increase efficiency .21) Although a large cache memory can hold more data , it also becomes slower .To compensate , computer architects employ designs with multiple caches . The design places the smallest and fastest cache nearest the CPU and locates a second large and slower cache farther away . This arrangement allows the CPU to operate on the most frequently accessed instructions and data at top speed and to slow down only slightly when accessing the secondary cache . Using separatecaches for instructions and data also allows the CPU to retrieve an instruction and data simultaneously .22) Anther strategy to increase speed and efficiency is the use of multiple arithmetic/logic units for simultaneous operations , called super scalar execution . In this design , instructions are acquired in groups . The control unit examines each group to see if it contains instructions that can be performed together . Some designs execute as many as six operations simultaneously . It is rare , however , to have this many instructions run together ,so on average the CPU does not achieve a six-fold increase in performance . 23) Multiple computers are sometimes combined into single systems called parallel processors . When a machine has more than one thousand arithmetic/logic units , it is said to be massively parallel . Such machines are used primarily for numerically intensive scientific and engineering computation .Parallel machines containing as many as sixteen thousand computers have been constructed .3-3 VLIW Microprocessors24) When Transmeta Corp. revealed its new Crusoe of processors last month ,experts weren’t surprised to learn that the chips are based on Very Long Instruction Word(VLIW)technology .VLIW has become the prevailing philosophy of microprocessor design , eclipsing older approaches such as RISC and complex instruction set computing(CISC) .25) All microprocessor designs seek better performance within the limitations of their contemporary technology. In the 70s of 20th century ,for example ,memory was measured in kilobytes and very expensive .CISC was the dominant approach because it conserved memory .26) In the CISC architecture . there can be hundreds of program instructions-simple commands that tell the system to add numbers, store values and display results. If all instructions were the same length , the simple ones would waste memory .Simple instructions require as little as 8 bits of storage space , while the most complex consume 120 bits .27) Variable-length instructions are more difficult for a chip to process, though, and the longer CISC instructions are especially complex. nonetheless ,to maintain software compatibility, modern chips such as Intel’s Pentium III and Advanced Micro Devices Inc.’s Athlon must still work with all troublesome CISC instructions that were designed in the 1980s , even though their original advantage-memory conservation-isn’t as important .28) In the 1980s , RAM chips got bigger and bigger in capacity while their prices dropped . The emphasis in CPU design shifted to relatively simple , fixed-length instructions , always 32 bits long .Although this wastes some memory by making programs bigger ,the instructions are easier and faster to execute .29) The simplicity of RISC also makes it easier to design superscalar processors-chips that can execute more than one instruction at a time .This is called instruction-level parallelism. Almost all modern RISC and CISC processors are superscalar. But achieving this capability introduced significant new levels of design complexity.30) VLIW chips can cost less , burn less power and achieve significantly higher performance than comparable RISC and CISC chips But there are always trade-offs. One is code expansion-programs grow larger , requiring more memory. Far more important , though , is that compilers must get smarter .A poor VLIW complier will have a much greater negative impact on performance than would a poor RISC or CISC compiler .31) VLIW isn’t a magic bullet , but it’s the new wave in microprocessor design .Within a few years , it’s certain that at least some of your software will be running on VLIW chips .单元3 电脑体系和微处理器3-1 电脑体系电脑体系，在电脑科技中，是一个依据整个或部分电脑结构的通用术语，这个术语也包含软件系统的设计，例如这个操作系统（控制电脑的程序），以及依据这个在电脑网络中连接主机的硬件和基本的软件的结合体。

Back in 1968, a computer scientist named Alan Kay proposed that with advances in flat-panel display technology, user interfaces, miniaturization of computer components and some experimental work in WiFi technology, you could develop an all-in-one computing device. He developed the idea further, suggesting that such a device would be perfect as an educational tool for schoolchildren. In 1972, he published a paper about the device and called it the Dynabook.The sketches of the Dynabook show a device very similar to the tablet computers we have today, with a couple of exceptions. The Dynabook had both a screen and a keyboard all on the same plane. But Key's vision went even further. He predicted that with the right touch-screen technology, you could do away with the physical keyboard and display a virtual keyboard in any configuration on the screen itself.Key was ahead of his time. It would take nearly four decades before a tablet similar to the one he imagined took the public by storm. But that doesn't mean there were no tablet computers on the market between the Dynabook concept and Apple's famed iPad.One early tablet was the GRiDPad. First produced in 1989, the GRiDPad included a monochromatic capacitance touch screen and a wired stylus. It weighed just under 5 pounds (2.26 kilograms). Compared to today's tablets, the GRiDPad was bulky and heavy, with a short battery life of only three hours. The man behind the GRiDPad was Jeff Hawkins, who later founded Palm.Other pen-based tablet computers followed but none received much support from the public. Apple first entered the tablet battlefield with the Newton, a device that's received equal amounts of love and ridicule over the years. Much of the criticism for the Newton focuses on its handwriting-recognition software.It really wasn't until Steve Jobs revealed the first iPad to an eager crowd that tablet computers became a viable consumer product. Today, companies like Apple, Google, Microsoft and HP are trying to predict consumer needs while designing the next generation of tablet devices.C.2 A Brief History of satellite communicationIn an article in Wireless World in 1945, Arthur C. Clarke proposed the idea of placing satellites in geostationary orbit around Earth such that three equally spaced satellites could provide worldwide coverage. However, it was not until 1957 that the Soviet Union launched the first satellite Sputnik 1, which was followed in early 1958 by the U.S. Army’s Explorer 1. Both Sputnik and Explorer transmitted telemetry information.The first communications satellite, the Signal Communicating Orbit Repeater Experiment (SCORE), was launched in 1958 by the U.S. Air Force. SCORE was a delayed-repeater satellite, which received signals from Earth at 150 MHz and stored them on tape for later retransmission. A further experimental communication satellite, Echo 1, was launched on August 12, 1960 and placed into inclined orbit at about 1500 km above Earth. Echo 1 was an aluminized plastic balloon with a diameter of 30 m and a weight of 75.3 kg. Echo 1 successfully demonstrated the first two-way voice communications by satellite.On October 4, 1960, the U.S. Department of Defense launched Courier into an elliptical orbit between 956 and 1240 km, with a period of 107 min. Although Courier lasted only 17 days, it was used for real-time voice, data, and facsimile transmission. The satellite also had five tape recorders onboard; four were used for delayed repetition of digital information, and the other for delayed repetition of analog messages.Direct-repeated satellite transmission began with the launch of Telstar I on July 10, 1962. Telstar I was an 87-cm, 80-kg sphere placed in low-Earth orbit between 960 and 6140 km, with an orbital period of 158 min. Telstar I was the first satellite to be able to transmit and receive simultaneously and was used for experimental telephone, image, and television transmission. However, on February 21, 1963, Telstar I suffered damage caused by the newly discovered Van Allen belts.Telstar II was made more radiation resistant and was launched on May 7, 1963. Telstar II was a straight repeater with a 6.5-GHz uplink and a 4.1-GHz downlink. The satellite power amplifier used a specially developed 2-W traveling wave tube. Along with its other capabilities, the broadband amplifier was able to relay color TV transmissions. The first successful trans-Atlantic transmission of video was accomplished with Telstar II , which also incorporated radiation measurements and experiments that exposed semiconductor components to space radiation.The first satellites placed in geostationary orbit were the synchronous communication (SYNCOM ) satellites launched by NASA in 1963. SYNCOM I failed on injection into orbit. However, SYNCOM II was successfully launched on July 26, 1964 and provided telephone, teletype, and facsimile transmission. SYNCOM III was launched on August 19, 1964 and transmitted TV pictures from the Tokyo Olympics. The International Telecommunications by Satellite (INTELSAT) consortium was founded in July 1964 with the charter to design, construct, establish, and maintain the operation of a global commercial communications system on a nondiscriminatory basis. The INTELSAT network started with the launch on April 6, 1965, of INTELSAT I, also called Early Bird. On June 28, 1965, INTELSAT I began providing 240 commercial international telephone channels as well as TV transmission between the United States and Europe.In 1979, INMARSAT established a third global system. In 1995, the INMARSAT name was changed to the International Mobile Satellite Organization to reflect the fact that the organization had evolved to become the only provider of global mobile satellite communications at sea, in the air, and on the land.Early telecommunication satellites were mainly used for long-distance continental and intercontinental broadband, narrowband, and TV transmission. With the advent of broadband optical fiber transmission, satellite services shifted focus to TV distribution, and to point-to-multipoint and very small aperture terminal (VSAT) applications. Satellite transmission is currently undergoing further significant growth with the introduction of mobile satellite systems for personal communications and fixed satellite systems for broadband data transmission.C.3 SmartphonesThink of a daily task, any daily task, and it's likely there's a specialized, pocket-sized device designed to help you accomplish it. You can get a separate, tiny and powerful machine to make phone calls, keep your calendar and address book, entertain you, play your music, give directions, take pictures, check your e-mail, and do countless other things. But how many pockets do you have? Handheld devices become as clunky as a room-sized supercomputer when you have to carry four of them around with you every day.A smartphone is one device that can take care of all of your handheld computing and communication needs in a single, small package. It's not so much a distinct class of products as it is a different set of standards for cell phones to live up to.Unlike many traditional cell phones, smartphones allow individual users to install, configure and run applications of their choosing. A smartphone offers the ability to conform the device to your particular way of doing things. Most standard cell-phone software offers only limited choices for re-configuration, forcing you to adapt to the way it's set up. On a standard phone, whether or not you like the built-in calendar application, you are stuck with it except for a few minor tweaks. If that phone were a smartphone, you could install any compatible calendar application you like.Here's a list of some of the things smartphones can do:•Send and receive mobile phone calls•Personal Information Management (PIM) including notes, calendar and to-do list•Communication with laptop or desktop computers•Data synchronization with applications like Microsoft Outlook•E-mail•Instant messaging•Applications such as word processing programs or video games•Play audio and video files in some standard formatsC.4 Analog, Digital and HDTVFor years, watching TV has involved analog signals and cathode ray tube (CRT) sets. The signal is made of continually varying radio waves that the TV translates into a picture and sound. An analog signal can reach a person's TV over the air, through a cable or via satellite. Digital signals, like the ones from DVD players, are converted to analog when played on traditional TVs.This system has worked pretty well for a long time, but it has some limitations:•Conventional CRT sets display around 480 visible lines of pixels. Broadcasters have been sending signals that work well with this resolution for years, and they can't fit enough resolution to fill a huge television into the analog signal.•Analog pictures are interlaced - a CRT's electron gun paints only half the lines for each pass down the screen. On some TVs, interlacing makes the picture flicker.•Converting video to analog format lowers its quality.United States broadcasting is currently changing to digital television (DTV). A digital signal transmits the information for video and sound as ones and zeros instead of as a wave. For over-the-air broadcasting, DTV will generally use the UHF portion of the radio spectrum with a 6 MHz bandwidth, just like analog TV signals do.DTV has several advantages:•The picture, even when displayed on a small TV, is better quality.• A digital signal can support a higher resolution, so the picture will still look good when shown on a larger TV screen.•The video can be progressive rather than interlaced - the screen shows the entire picture for every frame instead of every other line of pixels.•TV stations can broadcast several signals using the same bandwidth. This is called multicasting.•If broadcasters choose to, they can include interactive content or additional information with the DTV signal.•It can support high-definition (HDTV) broadcasts.DTV also has one really big disadvantage: Analog TVs can't decode and display digital signals. When analog broadcasting ends, you'll only be able to watch TV on your trusty old set if you have cable or satellite service transmitting analog signals or if you have a set-top digital converter.C.5 SoCThe semiconductor industry has continued to make impressive improvements in the achievable density of very large-scale integrated (VLSI) circuits. In order to keep pace with the levels of integration available, design engineers have developed new methodologies and techniques to manage the increased complexity inherent in these large chips. One such emerging methodology is system-on-chip (SoC) design, wherein predesigned and pre-verified blocks often called intellectual property (IP) blocks, IP cores, or virtual components are obtained from internal sources, or third parties, and combined on a single chip.These reusable IP cores may include embedded processors, memory blocks, interface blocks, analog blocks, and components that handle application specific processing functions. Corresponding software components are also provided in a reusable form and may include real-time operating systems and kernels, library functions, and device drivers.Large productivity gains can be achieved using this SoC/IP approach. In fact, rather than implementing each of these components separately, the role of the SoC designer is to integrate them onto a chip to implement complex functions in a relatively short amount of time.The integration process involves connecting the IP blocks to the communication network, implementing design-for-test (DFT) techniques and using methodologies to verify and validate the overall system-level design. Even larger productivity gains are possible if the system is architected as a platform in such as way that derivative designs can be generated quickly.In the past, the concept of SoC simply implied higher and higher levels of integration. That is, it was viewed as migrating a multichip system-on-board (SoB) to a single chip containing digital logic, memory, analog/mixed signal, and RF blocks. The primary drivers for this direction were the reduction of power, smaller form factor, and lower overall cost. It is important to recognize that integrating more and more functionality on a chip has always existed as a trend by virtue of Moore’s Law, which predicts that the number of transistors on a chip will double every 18-24 months. The challenge is to increase designer productivity to keep pace with Moore’s Law. Therefore, today’s notion of SoC is defined in terms of overall productivity gains through reusable design and integration of components.。
