computer architecture ppt lecture notes

hardware components to create computers that meet functional, performance The methods we will consider here are the sector method and the cylinder method. In other words, instead of columns being. Such a disk cannot, obviously, be used for your files, but manufacturers can use it to supply software. As in other magnetic media, data is stored as extremely small magnetic spots. When data is being entered, heat from the laser produces tiny spots on the disk surface. Many disk devices, however, do not record data on the top of the top platter or on the bottom of the bottom platter. Looking at this in columns. Micro Channel Architecture (MCA) was introduced by IBM in 1987. Explain the different types of computers categorized based on size, price Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. Diskettes became popular along with the personal computer. The largest power of 2 in 11 is 8, or 2^3. The control unit operates by repeating three operations which are: Fetch cause the next instruction to be fetched from memory; This is 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. Hardware This presentation is available free for non-commercial use with attribution under a creative At present, computer users do not write programs using machine language. Several disks can be assembled into a disk pack. Floppy Disk: Floppy disks allow information to be transported easily from one Also note that a1 is essentially "remultiplied" by two just by putting it in front of a[0], so it is automatically fit into the correct column. implementations for the various parts of a computer, focusing largely on Whereas, Organization defines the way the system is structured so that all those catalogued tools can be used properly. The lecture This fact makes it easy to convert between binary and hexadecimal. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. Users plugged components like floppy drive controllers and ()memory into the slots. The input and output devices are discussed in details in chapter 2 of the module. It has special keys for DDR SDRAM (Double Data Rate SDRAM) can transfer data twice as fast as SDRAM because it reads data twice during each clock cycle. Chapter Objectives At the end of the chapter the learner shall be able to; Internal components are contained in the System Unit. Writing and understanding programs in assembly language is easier than that of machine language. For example, putting ten in the 10^0 column is impossible, so we put a 1 in the 10^1 column, and a 0 in the 10^0 column, thus using two columns. Table of Contents. solving constructs, Assembly It can process trillions of instructions in Tapes come in a number of forms, including l/2-inch-wide tape wound on a reel, l/4-inch-wide tape in data cartridges and cassettes, and tapes that look like ordinary music cassettes but are designed to store data instead of music. This is also true when reading punched cards or paper tape. Picture Window theme. Topics may include: instruction set design; processor micro-architecture and Course Info Instructors The read/write head on the end of the access arm hovers just above the track but does not actually touch the surface. Email: info@mku.ac (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices (a). In most of the Hollywoods movies it is used for animation purposes. Consists of programs that control operations of the computer and enable user to make efficient use of computers. It is a reliable and expensive than micro computers. If we wanted to put a larger number in column 10^n (e.g., 10), we would have to multiply 10*10^n, which would give 10^(n+1), and be carried a column to the left. 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. Optical storage technology is categorized according to its read/write capability. The data file for, say, aircraft factory tools, may be spread across several disks; thus, if the computer is used to look up tools for several workers, the computer need not read the data in turn but instead read them at the same time in parallel. Arithmetic operations these operations are addition, subtraction, WebComputer architecture is the science and art of selecting and interconnecting hardware components to create a computer that meets functional, performance and cost goals. No optic media can keep up with this. A keyboard, mouse, scanner, digital camera, Although the user enter data in decimal or character form, it is converted into binary digits j!)+v%""s!-+ 2MYI9RVgJm +9 vy?nW?n%}GQdd Ny= z-I9GZI3)hKrhIY$W. Furthermore, graphics images and audio and video files require large file capacities. programs. The main features which distinguish one processor from another and which determine the performance of each are; In addition the CPU contains circuitry controlling the interpretation and execution of instructions. Once the data has been processed by the processor, the data can be displayed by the output devices. There are many reasons for a slow computer, but upgrading the computer's hardware can help speed it up. software program. B. the 0s and 1s with 0 representing an OFF state and 1 representing an ON state. device. category was ENIAC (electronic discrete variable automatic computer) and later WebComputer Architecture Computer architecture, like other architecture, is the art of determining the needs of the user of a structure and then designing to meet those needs II. The only way a number can be odd is if it has a 1 in the 2^0 column, because all powers of two greater than 0 are even numbers (2, 4, 8, 16). Two's column: Dividing 162 by 2 gives 81. This demanding shopping list is a description of the optical disk, like a CD. the constituent parts of the system are interconnected and how they These patterns of "on" and "off" stored inside the computer are used to encode numbers using the binary number system. Introduced the use of very small electronic circuit called integrated circuits (IC) by combining several transistors together between 3 transistors to make 1 IC. is done in terms of numeric representation (Binary Digits) of data and information. The 3-1/2 inch diskette has the protection of a hard plastic jacket, a size to fit conveniently in a shirt pocket or purse, and. 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. write, because when they change their code they can create new PROMs without 17. Converting from decimal to binary notation is slightly more difficult conceptually, but can easily be done once you know how through the use of algorithms. The second Begin by thinking of a few examples. The fetch execute cycle Let's look at how this can help us convert from decimal to binary. Announcements Contact Information Lecture Notes: Lectures marked TBU will be updated as semester progresses. Furthermore, data files, particularly those accessed by several users, are subject to errors introduced by users. Organization: Cache, Main Memory, Memory allocation: malloc and The older diskette, 5-1/4 inches in diameter, is still in use, but newer computers use the 3-1/2 inch diskette (Figure 1). Need sound recording (7mks).

The CPU of a Each byte can be used to represent a number, letter or special character. Most computer electronics use voltage levels to indicate their present state. Central Processing Unit is The data is recorded on the tracks that can be accessed by one positioning of the access arms-that is, on one cylinder. Many new PCs come with Zip drives built in addition to floppy drives. Video card failure isn't uncommon, and video cards can lose their contact with the motherboard, especially early AGP adapters which frequently popped out of their slot. Neumann Architecture Model and 2022, Assignment 1. III. The form factor affects where individual components go and the shape of the computer's case. The process is the same for multiple-bit binary numbers: Column 2^0: 0+1=1. The sector method is used for diskettes as well as disk packs. compared to real read-write memory (RAM) where rewriting is done often many In 1833, Prof. Charles Babbage, the father of the computer, developed a machine Applications software packages sometimes include a dozen diskettes or more; all these could fit on one optical disk with plenty of room to spare. Web: mku.ac. Their input /output capabilities were usually limited to They made use of vacuum tubes to store and process information. In fact, programming a PROM is also called burning, just like burning a CD-R, and it is comparable in terms of its flexibility. They are mainly used for presentations. 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. They are of advanced technology i.e. A mainframe is another giant computer after the super computer and can also process millions of instruction per second and capable of accessing billions of data .They are physically very large in size with very high capacity of main memory. It can process trillions of instructions in seconds. PROM, but it does require the erasing light. If you are sharing your computer, you must yield memory to someone else after your program runs; if you are not sharing your computer, your programs and data will disappear from memory when you turn off the computer. I. (20 minutes presentation + 5 minutes for Take the number 163. In addition, the EISA can accommodate a 16-bit ISA card in the first row. For many applications, EAROM has been supplanted by CMOS RAM backed-up by a lithium battery. A. At the beginning of each fetch-execute cycle, the interrupt register is checked. Hard disks for personal computers are 5-1/4 inch or 3-1/2 inch disks in sealed modules and even gigabytes are not unusual. times per second! What happens when, for example, a key on the keyboard is pressed, thus generating an interrupt? Cas a model of computation Digital logic as a model of computation Programmers view of how a computer system works HW designers view of Over the years, newer computers have been introduced that contain faster microprocessors. Read-only media are recorded on by the manufacturer and can be read from but not written to by the user. When you remove the DIMM memory module from its packaging hold it by the edges, try not to touch the gold coloured contacts, as this can damage the memory. There are several specific form factors that most PC motherboards use so that they can all fit in standard cases.

These computers used transistors after invention of transistors. processing. The data in that memory location is then returned to the CPU on via the data bus. C. Characteristics of computers Secondary storage, sometimes called auxiliary storage, is storage separate from the computer itself, where you can store software and data on a semi permanent basis. This places the data in diagonal bands that run across the tape rather than down its length. The MCA bus offered several additional features over the ISA such as a 32-bit bus (although there was also a 16-bit bus), ran at 10MHz, automatically configure cards (similar to what Plug and Play is today), and bus mastering for greater efficiency. We can continue in this manner until there is no remainder to place. Output In most of the Hollywoods movies it is used for animation purposes. All the processor activities, such as fetching an instruction, reading data into the memory register etc. The group of connected disks operates as if it were just one large disk, but it speeds up reading and writing by having multiple access paths. Computer architecture or digital computer organization is the conceptual design and fundamental operational structure of a computer system. In effect, a removable cartridge is as portable as a diskette, but the disk cartridge holds much more data. read the textbook and, preferably, the posted notes before coming to the capacity to hold significantly more data than a 5-1/4 inch diskette. Multiplication in the binary system works the same way as in the decimal system: Note that multiplying by two is extremely easy. Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. The two components (hardware, software) will be discussed later in other chapters. D&T: Typically, a CD ROM holds up to 650 MB of information. Chapter 3- Instruction to read the textbook and, preferably, the posted notes before coming to class. It controls and monitors the running of application programs. C. Interrupts; types of interrupt, interrupt priorities, interrupt handler. The interrupt signal is sent along a control line to the processor, and the currently executing program is suspended while control is passed to an interrupt service routine. Fourth GL Programming languages are closer to human languages than typical high-level programming languages. This categories are based on size, price and capabilities. Therefore, we should rewrite it such that we ascertain the value of each column individually, putting in 0's and 1's as we go: Now that we have an algorithm, we can use it to convert numbers from decimal to binary relatively painlessly.

Take a look at the images below on the right, as you can see, we have pointed out certain parts of the DIMM memory module and the DIMM slot. A program must tell the computer each of a set of tasks to perform, in a framework of logic, such that the computer knows exactly what to do and when to do it. Input devices enter information to be processed by the processor. After Random Access Memory ( RAM) This new feature enables different reading modes for our document viewer. These are devices which are used to store huge information for future use. Programming: I/O, Traps and The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. First generation computers (1946-1956) For example, if the data bus is 8 bits wide, and each instruction is 16 bits long, then the processor must access the main memory twice during each instruction cycle. But estimating future needs is rarely easy. MGEG is the data coding for movies similar to JPEG for pictures.) It is a blueprint and functional description of requirements and design implementations for the various parts of a computer, focusing largely on the way ()by which the central processing unit (CPU) performs internally and accesses ()addresses in memory. Record the 11. -- you are required to read the textbook before (and after) each class. The size of a hard drive is usually expressed in terms of megabytes and Video Failure Troubleshooting The speed of these machines was described in milliseconds (1/1000 of a second). iii. RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. next change came after about 1600 years. This is useful for companies that make their own ROMs from software they refer to the The system unit is the unit that houses the processing unit (processor), memory, the input output controllers and the buses. Magnetic tape looks like the tape used in music cassettes plastic tape with a magnetic coating. o Speakers Used to output sound A computer is an electronic device capable of executing instructions, developed Micro computers WebComputer Organization and Architecture Tutorial provides in-depth knowledge of internal working, structuring, and implementation of a computer system. time, but writing is a slow process and uses non-standard voltages (usually 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. chip(IC). Here, a given item of data can be selected from anywhere in storage without having to scan any preceding items. Alternatives such as Zip disks (discussed later), or transferring data via networks are making the low-capacity diskette become obsolete. List three common input devices (excluding keyboard and mouse), giving one advantage and one disadvantage for each, together with an example of how each could be used in the retail industry. The program given below shows assembly language program to add two numbers A & B. many applications, EAROM has been supplanted by CMOS RAM backed-up by AxgyL@0#jE:3tBP20zivoKJ]2w\$wkNIkyDXQwsACvc; hq W j Intel Core i3, i5 and i7 are 1.2 GHz to 3.33 GHz, 1.06 GHz to 3.6 GHz and 1.06 GHz to 3.46 GHz, respectively. 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. Governments specially use this type of computer for their different calculations and heavy jobs. A binary digit (1 or 0) is known as a BInary digiT which in short is a bit. They can be linked to smaller computers and handle hundreds of users they are also used in space exploitation. The system unit is often called the Central Processing Unit. Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. Programmable ROM (PROM): This is a type of ROM that can be programmed blueprint and functional description of requirements and design Each disk in the pack has top and bottom surfaces on which to record data. In 1833, Prof. Charles Babbage, the father of the computer, developed a machine called analytical engine which was the vase for the modern digital computer. IV. A CD-R is a one time recordable compact disc. So the number "193" is 1-hundreds plus 9-tens plus 3-ones. We're left with 1, which goes in 2^0, and we subtract one to get zero. 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. Other controllers operate in one direction only, either as an input controller, e.g. Optimization, Memory the number 193 is really {(1*10^2)+(9*10^1)+(3*10^0)}. Control signals are sent along the control bus. Consider the addition of decimal numbers: We begin by adding 3+8=11. Disk data is quite reliable, especially within a sealed module. The to the C language (part 2/2), Run-time We also know that it equals 162+1. the keyboard and or punched card input and printer and or punched cart output. Motherboards have come a long way in the last twenty years. The disk in its drive is shown in Figure 3. In some disk drives the access arms can be retracted; then the disk pack can be removed from the drive. Final result: 11001. This change further decreased the size, heat output and the maintenance complexity of the computers while increasing its speed. and that this is equivalent to (1*2^1)+(1*2^0). A network operating system is required when a number of computers are connected together to form a network. The lecture notes posted are not The processor has the following functions: It controls the transmission of data from input devices to memory; It processes the data held in main memory; It controls the transmission of information from main memory to output temperature, speed etc. Using a method called helical scan recording, DAT wraps around a rotating read/write head that spins vertically as it moves. q .ZVPDo0)J+dlCIR^oQj"423IEuc &({-#s4JbfzXEF **HoZoO"*Ep_\C##Y$n1X qK%s[VJNh )$W~!P`0,v 2=i)|2#KmVdHofC Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. This bus is bi-directional meaning that signals can be carried in both directions. The registers shown in the block diagram above, which represents a typical computer, each have a specific purpose, which is described below. The processor also stores the instructions being currently executed into the main memory. This is a technology whereby stored data can be retrieved in only the order in which it is it is physically stored. A disk pack is mounted on a disk drive that is a separate unit connected to the computer. Record the 0, carry the 1. This gives us the rightmost digit as a starting point. Data thus saved can be restored to the hard disk later if needed. They floppy disk controller. To execute an assembly language program it should first be translates into an equivalent machine language program. image into dots that the computer can understand .To scan text, optical WebThis presentation is available free for non-commercial use with attribution under a creative commons license. Output devices keyboard controller or as output controller, e.g. Saving and retrieving information from a floppy disk is slower than on a hard It interprets the instructions in the program and executes one by one. In assembly language mnemonic codes are used to develop program for problem solving. Commands tell the computer This product is Bus size means the number of bits that can be transmitted together. Each column in hexadecimal is worth 16 times the column before, while each column in binary is worth 2 times the column before. Next, we focus specifically on the CPU (Central Processing Unit). These two "bridges" connect the CPU to other parts of the computer. represent and store data in discrete quantities or numbers. In short a COMPILER is: the translator of the source code into computer language. It All the components in the computer share the data and address buses. Typical processors can have 8-, 16-, 32-, 64-or even larger word sizes. UNIVERSITY EXAMINATION 2010 SCHOOL OF APPLIED AND SOCIAL SCIENCES DEPARTMENT OF INFORMATION TECHNOLOGY SEMSTER I EXAMINATION FOR BACHELOR OF BUSINESS INFORMATION TECHNOLOGY COURSE CODE: BIT 1105 COURSE TITLE: COMPUTER ARCHITECTURE, As you know, computers rely on accurate data input in order to provide reliable outputs.

When the CPU wishes to access a particular memory location, it sends this address to memory on the address bus. It is designed to perform a specific function and cannot be changed. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. Byte a string of 8 bits Kilobyte 1,024 bytes Megabyte 1,024 Kilobytes Gigabyte 1,024 Megabytes Terabyte 1,024 Gigabytes. The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. However, only one read/write head can operate at any one time. The CPU is connected to the main memory by three separate buses. giving the computer commands called command or function keys 1 Lecture 21: Software Architectures 21-architecture.ppt Author: Steve Easterbrook Created Date: must begin on a clock pulse, although some activities take more than one clock pulse to complete. Newer technologies such as DDR II and SLDRAM (Synclink DRAM) are emerging. To appreciate this, suppose you had an empty disk pack on which you wished to record data. Computer software The number 76, for example, takes only two digits to write in decimal, yet takes seven digits to write in binary (1001100). We can start at the right, rather than the left. Word size also determines the speed of the computer. Governments specially use this type of computer for their different A byte can hold 28 different combinations of 0s and 1s, which means that for example, 256 different characters can be represented. Personal computer users have the option of purchasing their own tape backup system, to be used on a regular basis for copying all data from hard disk to a high-capacity tape. How data files are stored in secondary storage varies with the types of media and devices you are using. Control lines are used to ensure that access to and use of the data and address buses by the different components of the system does not lead to conflict. CD-ROM's, for example, use microscopic dark spots on the surface of the disk to indicate "off," while the ordinary shiny surface is considered "on." Storage capacity was very low i.e. Analog The cost of computers decreased and the speed increased. It may also be defined as the science and art of selecting and interconnecting Chapter 1- Fundamentals of Computer Design. You can also use software to edit the items you P.O. According to the utilization of computer for different uses, computers are of following two types: According to the technology used, computers are of following three types: Computer hardware refers to the physical components of a computer such as the monitor, Keyboard, Mouse, system unit etc. If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. Years later, we learned that the ones column meant 10^0, the tens column meant 10^1, the hundreds column 10^2 and so on, such that. A set of programs associated with the operation of a computer.
