with the ISA. The first in the Windows series was Windows 3.11 and the latest being Windows Vista. Assembly language is designed mainly to replace each machine code with and understandable mnemonic code. You should also refer to the lecture notes available from the textbook website. Similarly, the statement a[n-1]*2^(n-1) + a[n-2]*2^(n-2) + + a[1]*2^0 has a power of two removed. Similarly, multiplying by 2 shifts in the other direction: {a[n]*2^n + a[n-1]*2^(n-1) + + a[1]*2^1 + a[0]*2^0}/2. Disk, Virtual Memory, An easy to use digital logic design simulator is available. WebEC8552 Computer Architecture and Organization Lecture Notes, Syllabus & Important Questions (Regulation 2017) EC8552 Computer Architecture and Organization.Pdf DOWNLOAD (Including Syllabus, Lecture Notes, 2 Marks & 16 Marks with Year Wise Question Paper Collections) We are very Happy to Provide your all Requirements in a 2 0 obj solving constructs, Assembly We can easily see that the number 3= 2+1. Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components. Diskettes offer particular advantages which, as you will see, are not readily available with hard disk: The end of the diskettes useful life-time may be upon us. Computer software Recording the data vertically, on the other hand, substantially reduces access arm movement. The binary system works under the exact same principles as the decimal system, only it operates in base 2 rather than base 10. peripherals can be attached to them. Need sound recording The micro chip technology has enabled reduction of size of computers. The highest-capacity tape is the digital audio tape, or DAT, which uses a different method of recording data. to the C language (part 2/2), Run-time The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. The take-up reel always stays with the magnetic tape unit. The cost of computers decreased and the speed increased. memory. In fact, programming a PROM is also called burning, just like burning a CD-R, and it is comparable in terms of its flexibility. First generation computers (1946-1956) The laser beam is set to two different intensities, strongest for reading the underlying silver layer. This is even, so we put a 0 in the 8's column. next change came after about 1600 years. Put 1 in the 2^3 column, and 0 in 2^4 and 2^5. (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. Output devices A disk pack has a series of access arms that slip in between the disks in the pack. If you cannot divide the binary number evenly into blocks of four digits, add zeros to the left side of the number to make it work. ROM: A mask programmed read only memory that can be only be produced by computational machines. 2 Central Processing Unit (CPU)/Processor: It is the main part of a computer system like the brain of a human being. Output capability of retrieving data on a huge basis. They made use of vacuum tubes to store and process information. In Fig 1.3 you can see the ejector clips (D), using your finger, push these into the down position as shown in Fig 1.3, this allows the memory to be inserted. The set of instructions is often called a program or, if the set is particularly large and complex, a system. The micro chip technology has enabled reduction of size of. A given amount of data that takes up 1 inch of a track on the inside of a disk might be spread over several inches on a track near the outside of a disk. A keyboard, mouse, scanner, digital camera, touch pads and joystick are examples of input devices. A disk pack is mounted on a disk drive that is a separate unit connected to the computer. The binary number system is a method of storing ordinary numbers such as 42 or 365 as patterns of 1's and 0's. Graphical user interface has some disadvantages such as. Final result: 11001. It acts as an intermediate store between the CPU and the maim memory, and works by storing the most frequently or recently used instructions and data so that it will be very fast to retrieve them again. Topics may include: instruction set design; processor micro-architecture and Course Info Instructors ROM package, through which you can actually see the chip that holds the The form factor is just one of the many standards that apply to motherboards. iv. The 17 GB disk holds 200 hours top quality music recording. Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port. Representations -- Datatypes and Obviously this is much more useful than a regular PROM, but it does require the erasing light. does not cover memory design in any depth and I will provide detailed Looking at this in columns. I don't mean that hard drives last longer than memory modules or video cards in the pure MTBF (Mean Time Between Failure) sense, I mean they are rarely at fault when you're called in to repair a PC. Chapter 1- Fundamentals of Computer Design. Try converting these numbers from binary to decimal: | | | 1 | 0 | | 1 | 1 | 1 1 | 0 | 1 | 0 | 1 1 | 1 | 1 | 1 | 0. implementations for the various parts of a computer, focusing largely on Invention of IC revolutionalised electronics and started the error of micro-electronics. D. Hard Drive Failure Troubleshooting, V. Input and output devices and interrupts. Many users, therefore, make later adjustments like adding a removable hard disk cartridge to accommodate expanding storage needs. Since these programs use only '0's and '1's it will be very difficult for developing programs for complex problem solving. This bus is bi-directional meaning that signals can be carried in both directions. They can be used as servers in companies. System Design which includes all of the other hardware components They are slower and less costly compared to mainframe computers but more powerful, reliable and expensive than micro computers. Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. A byte can hold 28 different combinations of 0s and 1s, which means that for example, 256 different characters can be represented. slower and less costly compared to mainframe computers but more powerful, The tubes Continue counting once again: 20, 21, 22, , 29, 2A, 2B, 2D, 2E, 2F, 30, 31, 32, , 3E, 3F, 40, 41, 42, 99, 9A, 9B, 9C, 9D, 9E, 9F, A0, A1, A2, F9, FA, FB, FC, FD, FE, FF, 100, 101, 102, . Watch the pattern of numbers and try to relate this to the way you count in decimal or binary. Hardware units (Devices) of a computer can be categorized into five units; An input device lets you communicate with a computer. Zip disks are a great way to store large files and software programs. Software FACE RECOGNITION AND SIMILAR, Structure and Interpretation of Computer Programs, TEXTURE ANALYSIS USING SPECTRAL TRANSFORMS. just like burning a CD-R, and it is comparable in terms of its flexibility. Commands tell the computer to do something, like save the file. They are Such a disk cannot, obviously, be used for your files, but manufacturers can use it to supply software. This kind of computer is also helpful for forecasting weather reports worldwide. Magnetic tape looks like the tape used in music cassettes plastic tape with a magnetic coating. D=0, so we are done, and the decimal number 163 is equivalent to the binary number 10100011. In order to synchronise the various steps carried out during the fetch-execute cycle, all the processors have an internal clock which generates regularly timed pulses. But this is not practical for a system with many files or many users. notes posted are not meant to substitute for the text With IC you can house thousands of transistors in one IC. A computer has to main components; A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be 2kb and speed of processing was also very low. C. Interrupts; types of interrupt, interrupt priorities, interrupt handler. hardware components to create computers that meet functional, performance for instance, is an organizational issue that generally has nothing to do Only an interrupt with a higher priority is allowed to interrupt the servicing of another. Many new PCs come with Zip drives built in addition to floppy drives. Use large scale integration circuits which housed hundreds of transistors and very large IC which are between 200,000 to 400, 000 in one IC. To converty from binary to hexadecimal, reverse the procedure and break the binary number into blocks of four digits. Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." A concept of using several small disks that work together as a unit is called a redundant array of inexpensive disks, or simply RAID. Instead of using the digits 0-9, we only use 0-1 (again, if we used anything larger it would be like multiplying 2*2^n and getting 2^n+1, which would not fit in the 2^n column. Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. dj z(l6uHyB"C]Iie7tHDXWq@vd4KfqS)YZT&;"v%LqNm!ZTJ UWBD@^-1QA+'6b"V0s>x$*Y l(7`yAP. Zone recording involves dividing a disk into zones to take advantage of the storage available on all tracks, by assigning more sectors to tracks in outer zones than to those in inner zones. Temporary Result: 11 New D=40 D does not equal 0, so we repeat step 2. Let's try the number D=55. iii. For example, a transistor with five volts would be considered "on", while a transistor with no voltage would be considered "off." You should also refer to the lecture notes available from the textbook website. We can start at the right, rather than the left. The IBM 360 is an example of third generation computers. Examples: What would the binary number 1011 be in decimal notation? computer to another they have limited storage capacity, generally 1 MB. Box 342-01000 Thika info@mku.ac.ke Email: www.mku.ac.ke Web: Instructional Manual for BBIT Distance Learning. Two read/write heads are on each arm, one facing up for the surface above it and one facing down for the surface below it. So the number "193" is 1-hundreds plus 9-tens plus 3-ones. The basic functions of an operating system are; A stand a lone operating system controls a single computer that is not connected to others on a network. P.O. Hard Drive: In our vertical notation. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices They are smaller than the main frame but bigger than microcomputers. It Converts an The first motherboards held very few actual components. An operating system acts as foundation on which other application software can be installed. programmer, including the instruction set, word size, memory address Since we already knew how to convert from binary to decimal, we can easily verify our result. This method produces high density and faster access to data. They are of advanced technology i.e. Writing takes place in a single pass of the focused laser beam. Furthermore, graphics images and audio and video files require large file capacities. Put 1 in the 2^1 column, 0 in 2^2, and subtract 2 from 3. A little glass window is installed in the top of the A 4.7 GB side of a DVD can hold 135 minutes top quality video with 6 track stereo. The notches we have marked as B, are used to align the memory module with the DIMM slot keys C, as shown in Fig 1.3. Thus, our number is 1001011. A different ISR is provided for each different source of interrupt. The disk in its drive is shown in Figure 3. Different industries also use this huge computer for designing their products. Our "new" 2^0 column now contains a1. WebLecture notes of Prof David Brooks could also be referred. C. The motherboard; form factor, sockets and slots Instead of typing a command or file name, selection is achieved by moving a pointer with a mouse and clicking a mouse button. They are shown in the block diagram below. The term mainframe was mainly used for earliest computers as they were big in WebComputer architecture, like other architecture, is the art of determining the needs of the user of a structure and then designing to meet those needs as effectively as possible within economic and technological constraints. F.P. floppy disk controller. These suites offer four or more software products packaged together at a much lower price than buying the packages separately. The p ro c essor ; Ari th m eti c an d Logi c Unit , C ontro l U n it , sy st em You cannot read just any record at random. Since we divided the number by two, we "took out" one power of two. 10 INPUT A,B 20 LET C=A+B 30 PRINT C 40 END, To read the value of A&B A&B are added and result is stored in C Print the value of C Stop execution. In a command based interface the user enters commands through an interactive terminal. (0's and l's). Explain how the different units of a computer interact witch each other to MGEG is the data coding for movies similar to JPEG for pictures.) A rule of thumb among computer professionals is to estimate disk needs generously and then double that amount. II. The real time clock chip is a battery-operated chip that maintains basic settings and the system time. software Input devices enter information to be processed by the processor. Many disk devices, however, do not record data on the top of the top platter or on the bottom of the bottom platter. They are smaller than the main frame but bigger than microcomputers. All 4GLs are designed to reduce programming effort, the time it takes to develop software, and the cost of software development. Continuing the "CD" analogy, this technology is analogous to a reusable CD-RW. The high level languages commonly used are FORTRAN (FORmula TRANslation), BASIC (Beginner's All-purpose Symbolic Instruction Code), COBOL (COmmon Business Oriented Language). In these computers, all processing Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. The truth is, of all the four subsystems represented in this table, hard drives are probably the most reliable. At the end of the chapter the learner shall be able to; Lecture Notes on Computer Architecture November 2018 Authors: Firoz Mahmud Rajshahi University of Engineering & Technology Figures Content uploaded by << /Length 4 0 R /Filter /FlateDecode >> Used to put printed pictures and text into a computer. drive.

The first place to start is always confirming that the power supply is operating properly. The external components of a computer are called peripheral devices which include input and output. Peripheral Component Interconnect (PCI)-connections for video, sound and, video capture cards, as well as network cards, Integrated Drive Electronics (IDE) -interfaces for the hard drives. Because of their digital nature, a computer's electronics can easily manipulate numbers stored in binary by treating 1 as "on" and 0 as "off." The tubes consumed a lot of power and generated a lot of heat (overheating). In assembly language mnemonic codes are used to develop program for problem solving. DDR SDRAM (Double Data Rate SDRAM) can transfer data twice as fast as SDRAM because it reads data twice during each clock cycle. Assembly language is translated into machine code using an assembler before they can be executed. Binary addition works on the same principle, but the numerals are different. In such a system a task is broken down and shared among processes to be reprogrammed again. This new feature enables different reading modes for our document viewer. DVD disks are read by a laser beam of shorter wave-length than used by the CD ROM drives. This is useful for companies that make their own ROMs from software they It can process trillions of instructions in seconds. seconds. How data files are stored in secondary storage varies with the types of media and devices you are using. Most mainframe computers have 32-bit words. The control unit coordinates and controls all the operations carried out by the the most flexible type of ROM, and is now commonly used for holding BIOS This document should be seasone Computer Architecture and Assembly Language Programming, Computer Organization and Design 4th Edition Solution, Comporg 6 sol2 - Solution manual for the second Chapter of the Computer Architecture, CS401 Quiz 1 Solution by MCS of Virtuallians. classified and known as super computer. and to perform computations on these measurements. The easy cases to diagnose are those where the monitor or LCD isn't powering up properly, or the PC not powering up. B. A Bus is a set of parallel wires connecting two or more components in a computer. In binary, any digit higher than 1 puts us a column to the left (as would 10 in decimal notation). A CD-RW allows you to read, write, erase and write again. Once full, a removable hard disk cartridge can be replaced with a fresh one. Whereas, Organization defines the way the system is structured so that all those catalogued tools can be used properly. The processor has the following functions: The control unit coordinates and controls all the operations carried out by the computer. Using a method called helical scan recording, DAT wraps around a rotating read/write head that spins vertically as it moves. There are very few instances when you'd turn on a PC, have it either power up or not, and be able to say, "Oh, that's a motherboard problem." 1 Lecture 21: Software Architectures 21-architecture.ppt Author: Steve Easterbrook Created Date: B. Ultraviolet light of a specific frequency can be shined through this window for a specified period of time, which will erase the EPROM and allow it to be reprogrammed again. infrequent operation - most of the time the memory is used as a ROM. powerpoint format) I will post detailed notes that will go into The OS controls who logs on to the network by means of user names and passwords, in order to protect the data and programs stored on the network. to the C language (part 1/2), Introduction P. Box 342-01000 Thika This demanding shopping list is a description of the optical disk, like a CD. This change further decreased the size, heat output and the maintenance complexity of the computers while increasing its speed. the required results faster than human beings.

The two components (hardware, software) will be discussed later in other chapters. Nguyen Quoc Trung. Explain the different types of computers categorized based on size, price No optic media can keep up with this. Web1 cache.1 361 Computer Architecture Lecture 14: Cache Memory cache.2 The Motivation for Caches Motivation: Large memories (DRAM) are slow Small memories (SRAM) are fast Make the average access time small by: Servicing most accesses from a small, fast memory. Microarchitecture, also known as Computer organization is a lower level, Four's column: Now we can subtract 1 from 81 to see what remainder we still must place (80). They are used to control the computer and develop and run application programs examples of jobs done by the system software are management of computer resources, defragmentation etc. Computers, in contrast, permit storage on tape or disk in extremely compressed form. The organization in this case is vertical. 1 Software and Hardware Chapter 2- Basic Organization of a Computer. image into dots that the computer can understand .To scan text, optical The speed of these machines was described in milliseconds (1/1000 of a second). Binary is an effective number system for computers because it is easy to implement with digital electronics. Computers have circuits that can add, subtract, multiply, divide, and do many other things to numbers stored in binary. Data are raw facts and ideas that have not been processed while Information is data that has been processed so as to be useful to the user, Software can be broadly classified into system software and application software. This requires a transmission rate of 4692 bits per second. WebUniversity of Toronto Department of Computer Science 2004-5 Steve Easterbrook. Following this, the changes were When we first learned about numbers, we were taught that, in the decimal system, things are organized into columns: such that "H" is the hundreds column, "T" is the tens column, and "O" is the ones column. notes that you will be expected to read before class. To multiply by two, just add a 0 on the end. Memory used includes magnetic disc and optical disc. The fetch execute cycle The supply reel, which has the tape with data on it or on which data will be recorded, is the reel that is changed. Icons represent programs, groups of programs, folders, devices and files. These computers used transistors after invention of transistors. C. Motherboard and CPU Troubleshooting The size of a hard drive is usually expressed in terms of megabytes and Removable units also are important to businesses concerned with security, because the units can be used during business hours but hidden away during off hours. calculations and heavy jobs. However, you probably want to store the data you have used or the information you have derived from processing; that is why secondary storage is needed. But estimating future needs is rarely easy. Picture, if you can, how many filing-cabinet drawers would be required to hold the millions of files of, say, tax records kept by the Internal Revenue Service or historical employee records kept by General Motors. Topics may include: instruction set design; processor micro-architecture and Internal hardware of a computer. (Photo openphoto.net. Used with permission.)

Kurose,W. integration that confines several physical components per small elements thumb The purpose is to reduce the time it takes to move the access arms of a disk pack into position. B. The following are the different types of interrupt that could occur; There is a special register in the CPU called the interrupt register. Research shows that the trend in computer technology revolution is that there is; A computer is an electronic device capable of executing instructions, developed based on algorithms stored in its memory, to process data fed to it and produce the required results faster than human beings. In order to execute a high-level language program, it should be translated into a machine language either using a compiler or interpreter. Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. Micro Channel Architecture (MCA) was introduced by IBM in 1987. They come highly recommended. Input unit IV. Announcements Contact Information Lecture Notes: Lectures marked TBU will be updated as semester progresses. That means that their electronic circuits can exist in only one of two states: on or off. i.e., the programs were machine dependent. The i3 is solely a dual-core CPU; the i5 offers dual-and quad-core choices; and the i7 is split into dual-, quad-and six-core choices. @@TTA Rewriting an EAROM is intended to be an Continuing the "CD" analogy, this The class will review fundamental structures in modern microprocessor and computer system architecture design. Tentative topics will include computer organization, instruction set design, memory system design, pipelining, and other techniques to exploit parallelism. 10 times the past. However, only one read/write head can operate at any one time. To provide an in-depth presentation of computer hardware and software with There are several specific form factors that most PC motherboards use so that they can all fit in standard cases.
