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。

My name is Tommy and I'm 9 years old. Today I want to tell you all about my favorite topics to learn about in school - information science and electronic engineering! I find this stuff super fascinating.Let's start with information science. This is all about how we collect, store, and use data and information. In class, we've learned about databases, which are like giant collections of information all stored together. Databases allow you to keep track of lots and lots of data in an organized way.For example, let's say you have a database of all the books in a library. The database would have an entry for each book, with details like the title, author, year it was published, and what section of the library it's located in. With a database, you can easily search for a specific book or books on a certain topic.We've also learned about data mining, which is how you can analyze all the data in a big database to find hidden patterns and trends. It's like being a detective and using clues to crack a case, except the clues are all the data points! Companies use data mining on their customer databases to better understand what people want to buy.Another key part of information science is data visualization. This is how you take data and present it in easy-to-understand visual ways like charts, graphs, and infographics. One of the coolest data viz techniques I've learned about is heat mapping, where you use different colors almost like a weather map to show things like website traffic or prices across a geographic area.Information science is all about turning giant pools of raw data into useful information and insights. Pretty amazing stuff when you think about just how much data exists today between the internet, business records, scientific research, and more!Now let's talk about the other topic I love - electronic engineering. This is figuring out how to design and build all the awesome electronic devices and systems that make the modern world go round.We've covered basic circuits in class, like how a simple circuit has a power source like a battery that provides the energy to make electrons flow through a conductor like a metal wire. By adding other components like switches, resistors, and lightbulbs, you can control and manipulate that flow of electricity to do useful things.From there, we've built up to more complex circuits using transistors, which are like solid-state switches that can amplify or transform electrical signals. Transistors are one of the fundamental building blocks of all modern electronics and computing. Billions of teeny tiny transistors are crammed into the microchips that act as the "brains" of smartphones, computers, and so much more.In addition to circuits and microchips, we've learned about other electronic devices and components like capacitors for storing electric charge, transformers for increasing or decreasing voltage, and all sorts of sensors for detecting things like light,sound, and motion. We even built our own basic robots by wiring up little motors and sensors to a microcontroller chip!Another amazing area of electronic engineering is communications systems - things like radio, television, internet, and wireless data networks. We learned how data can be encoded into electromagnetic waves and transmitted through the air, along cables, or via fiber optic lines. Multiplexing techniques allow tons of separate signals and channels to be combined together and transmitted simultaneously.On the receiving end, devices like radios and modems decode the incoming signals to recover the original data. Routers, switches, and other networking gear help route the data to its intended destination. Just think about how much electronic wizardry has to happen for you to simple send a text message or stream a video!My absolute favorite part of electronic engineering is imagining and designing all the cool future technologies that will one day exist. Technologies like laser-powered data transmission, quantum computers, and lifelike robotics and artificial intelligence seem like total science fiction now. But I can't wait to see what incredible new electronic marvels get invented as scientists and engineers keep pushing the boundaries.Well, that's my overview of why I find information science and electronic engineering so amazing. At their core, both fields are all about harnessing data and electricity to create powerful tools and technologies that can reshape how we live and understand the world around us. Just imagining where these disciplines will go next gets me incredibly excited!I have so much more to learn, but I feel like I'm getting a great foundation. Who knows, in 20 years I may be the one helping design quantum computer microchips or developing new data mining techniques to analyze zettabytes of information! For now though, I better get back to studying. This stuff is just endlessly fascinating to me. Thanks for reading, talk to you later!篇4My Big Sister Is An EngineerI love my big sister Emily! She's the coolest and smartest person I know. Emily is studying to be an engineer at university. At first, I didn't really understand what that meant, but now I think it's super awesome!Emily studies something called "Information Science and Electronic Engineering." That's a really long name, but she explained it to me in a way I could understand. You see,engineers are like modern-day wizards who use science and math to create amazing things that make our lives easier and more fun!Information Science is all about computers, the internet, and how we share and use information.

It's like having a superpower!Emily says that engineers have to be good at math, science, and problem-solving. They have to think logically and creatively to find solutions to all kinds of problems. Sometimes, she has to work on projects with her classmates, which teaches her how to collaborate and communicate well with others.One of the things I admire most about Emily is how hard she works. She spends hours studying, doing homework, and working on projects. But she doesn't seem to mind because she's so passionate about what she's learning. She says that every day is an opportunity to discover something new and exciting.I can't wait until Emily graduates and gets a job as an engineer. Who knows, maybe she'll design the next big video game console or help build a rocket that takes people to Mars! The possibilities are endless when you're an engineer.Sometimes, when I'm playing with my Lego sets or trying to figure out a puzzle, I imagine myself as an engineer like Emily. I pretend that I'm building a giant robot or designing a new kind of computer. It's so much fun to let my imagination run wild and think about all the amazing things I could create someday.Emily says that the world needs more engineers to help solve problems and make life better for everyone. She always encourages me to study hard, especially in math and science, because those subjects will help me become a great engineer too if I want.I'm not sure yet if I want to be an engineer when I grow up, but I know that whatever I choose to do, I want to be just like my big sister Emily – smart, creative, hardworking, and always eager to learn new things.For now, I'll keep playing with my Legos, tinkering with my toys, and dreaming big dreams. Who knows, maybe one day I'll be the one building amazing robots or designing the next generation of computers and gadgets. With an engineer like Emily as my role model, anything seems possible!篇5My Big Sister's Awesome JobHi there! My name is Tommy, and I'm eight years old. I want to tell you all about my big sister Sarah and her really cool job. She's an Information Science and Electronic Engineering professional, which sounds super fancy and complicated, but I'lldo my best to explain it in a way that even a kid like me can understand.Sarah works with computers and electronics, which are like magic boxes that can do all sorts of amazing things. She helps make them work better, faster, and smarter. Isn't that awesome? Sometimes, she even gets to build new gadgets and gizmos from scratch!One of the things Sarah does is something called "coding." Now, I know what you're thinking – "Coding? That sounds boring!" But trust me, it's actually really exciting. Coding is like giving instructions to computers, sort of like telling your dog to sit or roll over, but way more complicated. Sarah uses special languages (not like French or Spanish, but like computer languages) to tell the machines what to do.For example, she might tell a computer to sort through a bunch of data and find specific information, or to control a robot arm in a factory. It's like she's a master magician, waving her wand (which is actually a keyboard) and making the computers do whatever she wants!Another part of Sarah's job is something called "hardware engineering." This means she gets to design and build the physical parts of computers and other electronic devices. It's likebeing a super-cool construction worker, but instead of building houses, she builds tiny little cities inside the machines!Sarah has shown me some of the gadgets she's worked on, and let me tell you, they're mind-blowing. There was this one thing that looked like a regular old box, but it could actually control the lights and temperature in our house just by talking to it. How crazy is that?But Sarah's job isn't just about coding and building stuff. She also has to solve lots of problems and figure out how to make things work better. Sometimes, things go wrong with computers or electronics, and it's her job to figure out what's causing the issue and fix it. It's like being a detective, but instead of looking for clues at a crime scene, she's investigating the inner workings of machines.Sarah says that one of the best parts of her job is getting to work with other really smart people. She's part of a team, and they all collaborate to come up with new ideas and solutions. It's like having a whole group of super-genius friends who all love computers and electronics as much as she does.Now, you might be thinking, "Wow, that sounds like a lot of hard work!" And you'd be right. Sarah has to study and learn new things all the time, and she often has to work late nights orweekends to meet deadlines. But she says it's all worth it because she loves what she does.You see, Sarah has always been fascinated by technology and how things work. When she was little, she used to take apart her toys and put them back together again (sometimes they even worked after!). She was always asking questions and trying to figure out how things worked.So, when it came time to choose a career, Information Science and Electronic Engineering was the perfect fit for her. She gets to work with the latest and greatest technology, and she's constantly learning and growing.Honestly, I'm still not entirely sure what Sarah does every day at her job, but I know it's something really important and exciting. And who knows, maybe one day I'll follow in her footsteps and become an Information Science and Electronic Engineering professional too!For now, though, I'm content to just listen to Sarah's stories and play with the cool gadgets she brings home from work. I might not understand all the technical details, but I know that my big sister has one of the coolest jobs in the world. And that's something to be proud of!篇6My Big Dream of Becoming an Awesome EngineerHi there! My name is Timmy and I'm 10 years old. I just finished 4th grade and can't wait for summer vacation! You know what I really love? I love science and building things. That's why I dream of becoming an amazing engineer when I grow up.Engineering is just the coolest thing ever. Do you know what engineers do? They get to design and create all sorts of awesome machines, robots, computers, phones, and other crazy gadgets! How awesome is that? Way better than being a boring teacher or accountant if you ask me.There are different types of engineers too. Information science engineers are like the brains behind all the technology we use every day. They design the software and programs that make our phones, laptops, and video games work. Without them, our devices would be basically just hunks of plastic and metal. Boring!Then you have electronic engineers who design the actual electronics and hardware inside our gadgets. They get to build circuit boards, processors, and all the tiny components that makeeverything run. It's like they get to play with ultra-tiny building blocks and wires all day long. So fun!I can't decide if I want to be an information science engineer or electronic engineer when I grow up. Maybe I'll do both! I'll design the software AND the electronics. Then I can create the whole product from scratch - nothing could stop me!Just imagine if I designed the next big gaming console or smart phone. I'd put in a blazing fast processor, tons of memory, and high-def graphics that would blow your mind. And I'd code all the games and apps too so you'd never get bored. It would be the hottest device ever and all the kids would beg their parents for one. I'd be rich AND famous!Or maybe I'll design robots instead. Not lame little robots that just vacuum, but awesome robots that can talk, play sports, or even fight crime. I'd make them super strong but also program them with artificial intelligence to be really smart. My robot squad could handle any problem or rescue any person in need. We'd be like a team of robotic superheroes protecting the world!Heck, if I'm really ambitious, I could even engineer entire cities of the future. Self-driving car systems, renewable energy grids, ultra-fast communication networks - I'd design it all. Thecities would basically run themselves with minimal human effort required. Everyone would live in modern, efficient luxury thanks to my brilliant engineering.Whoa, sorry, I got a little carried away dreaming there. Sometimes my big imagination gets the best of me. But isn't it crazy all the potential that engineers have? With their skills and knowledge, they can literally design our future world. That's why I'm going to study my butt off in math, science, and technology so I can grow up to be one.I may only be in elementary school now, but I'm already tinkering with electronics and coding as much as I can. My parents got me a basic robotics kit and I've been building simple rovers and robotic arms. I've also been teaching myself coding by making basic games and messing around on coding websites. It's never too early to start prepping to become an engineering prodigy!My friends think I'm a little weird always playing with circuits and computers instead of going outside. But who cares? I have huge plans that involve much more than just running around at the park all day. With hard work and perseverance, I'll get through all the tough engineering classes in college. Then I'llland my dream job designing the latest must-have technologies alongside other geniuses. We'll change the world together!Just you wait and see. In a couple decades, I may have engineered crazy holographic smartphones, sentient robot assistants, or self-sustaining colonies on Mars. The possibilities are endless because I'm going to be an engineering master of the future! Maybe you'll see my name in headlines or I'll become a legendary tech billionaire. Or maybe I'll just be quietly working behind the scenes, dreaming up must-have gadgets from my Silicon Valley lab. Whichever path I take, the world better brace itself for the insane creations of Timmy the Engineer!So yeah, that's my huge, epic dream career. What's your dream? Astronaut? Artist? Veterinarian? Whatever it is, just never stop dreaming big! Study hard, stay focused, and amazing things can happen, just like my coming engineering awesomeness. Okay, gotta go - I need to put some finishing touches on theAI-powered robotic puppy。
