computer architecture ppt lecture notes

When buying a computer the speed of the CD-ROM drive is advertised using an "X" factor, like 12X, or 24X. Almost all the computers used nowadays are digital computers and we will humans. This method produces high density and faster access to data. memory. SDRAM (Synchronous DRAM) divides RAM into two separate memory banks to increase the processing of the memory requests. It is designed to perform a specific function and cannot be storage In most of the Hollywoods movies it is used for animation purposes. To accommodate the increased speed, chip manufacturers have designed and built faster RAM chips. As you know, the decimal system uses the digits 0-9 to represent numbers. The two components (hardware, software) will be discussed later in other Microcomputers can be a desktop, laptop, notebooks, or even palmtop. Binary addition works on the same principle, but the numerals are different. They made use of vacuum tubes to store and process information. computer to another they have limited storage capacity, generally 1 MB. higher voltages around 12 volts). EISA is the second most commonly used interface for disk drives. This is useful for companies that make their own ROMs from software they 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. Compiler, Program The lecture 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 The pictures They are smaller than the main frame but bigger than microcomputers. A key advantage of a tape backup system is that it can copy the entire hard disk in minutes, saving you the trouble of swapping diskettes in and out of the machine. Some of the other standards include: The socket for the microprocessor determines what kind of Central Processing Unit (CPU) the motherboard uses. Number IV. size IC, hence the size reduced. generation saw the introduction of more complex ALU and CPU, the use of high represent and store data in discrete quantities or numbers. 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. Many new PCs come with Zip drives built in addition to floppy drives. In fact, flash memory is known as a solid state storage device, meaning there are no moving parts --everything is electronic instead of mechanical. They are shown in the block diagram below. 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. Output Hardware: input and output devices, backup storage, central processing Record the 0, carry the 1. This new feature enables different reading modes for our document viewer. versions, like the CD-ROM's. With any method of data storage, a backup system a way of storing data in more than one place to protect it from damage and errors is vital. Since Assembly language is machine dependent each type of computer has its own assembler. Topics may include: instruction set design; processor micro-architecture and Course Info Instructors Region one is USA and Canada, while Europe and Asia is region two. category was ENIAC (electronic discrete variable automatic computer) and later to be reprogrammed again. The disk in its drive is shown in Figure 3. III. A motherboard by itself is useless, but a computer has to have one to operate. There are different types of disk packs, with the number of platters varying by model. Many disk devices, however, do not record data on the top of the top platter or on the bottom of the bottom platter. These are devices which are used to store huge information for future use. computational machines. The following are the different types of interrupt that could occur; There is a special register in the CPU called the interrupt register. The first calculating device, which was used 2000 years ago was called abacus and the improvements in the calculating device in that age were slow. 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. erased and reprogrammed. Instead of typing a command or file name, selection is achieved by moving a pointer with a mouse and clicking a mouse button. The processor communicates and controls a peripheral device through an I/O or device controller. ROM package, through which you can actually see the chip that holds the software program. the manufacturer. ()Instruction set architecture, or ISA, is the abstract image of a computing ()system that is seen by a machine language (or assembly language()programmer, including the instruction set, word size, memory address ()modes, processor registers, and address and data formats. Compact Disk Read Only Memory (CD ROM): CD ROMs are read only storage medium. hardware components to create computers that meet functional, performance implementations for the various parts of a computer, focusing largely on The program given below shows assembly language program to add two numbers A & B. 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. There are many reasons for a slow computer, but upgrading the computer's hardware can help speed it up. The data is recorded on the tracks that can be accessed by one positioning of the access arms-that is, on one cylinder. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. 6.823 is a study of the evolution of computer architecture and the factors influencing the The processor also stores the instructions being currently executed into the main memory. A small program called an interrupt service routine (ISR) or interrupt handler is executed to transfer the character value f the key pressed into main memory. ii. the required results faster than human beings. A. These computers were mostly Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. Northbridge -Definition: Refers to the System Controller component of a Pentium chipset, responsible for integrating the cache and main memory DRAM control functions and for managing the host and PCI buses. o Keyboard Used to type data into the computer. B. 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.

Annals of Business Administrative Science, 16(2), 91-102. A computer has to main components; and accesses addresses in memory. Explain the characteristics of computers and how they are different from WebLecture notes Chapters 1-3, 5-12 The CMU ICS+ coursethat covers everything in CS:APP3e except Chapter 4 (Processor Architecture). Begin by thinking of a few examples. To provide an in-depth presentation of computer hardware and software with more emphasis on the more technical aspects of computing such as troubleshooting and upgrading computers. 9 The DVD is a flat disk, the size of a CD -4.7 inches diameter and .05 inches thick. The processor and main memory of a PC are commonly held on a single board This means that the tracks on the outside are not storing data as efficiently. To converty from binary to hexadecimal, reverse the procedure and break the binary number into blocks of four digits. 2 Input Devices Continue counting: 10, 11, 12, 13, 14, 15, 16, 17 18, 19, 1A, 1B, 1C, 1D, 1E, 1F. Input Devices Ch19 - Chapter 19 solution for Intermediate Accounting by Donald E. Kieso, Jerry J. Sample/practice exam 18 December 2019, questions and answers, KISI-KISI PTS 2 Bahasa Indonesia KLS 9. The two components (hardware, software) will be discussed later in other chapters. In effect, a removable cartridge is as portable as a diskette, but the disk cartridge holds much more data. 2. Using a method called helical scan recording, DAT wraps around a rotating read/write head that spins vertically as it moves. Following this, the changes were Examples operating systems that use command based interface are Ms Dos and Unix. Since we divided the number by two, we "took out" one power of two. ); it can be written to, but only The first column we fill is the rightmost column, which is 2^0, or 1. Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. x[r+&YU@lJSvB%d#QTD[/\{g\\S Tracks within a cylinder are numbered according to this vertical perspective: A 20-surface disk pack contains cylinder tracks numbered 0 through 19, top to bottom. This is similar to the way a CD-ROM recorder works by letting you "burn" programs onto blanks once and then letting you read from them many times. These computers are used in networking .examples of micro computers are IBM PCs BBC micro etc. Here is a link to some online notes that I found to be well the constituent parts of the system are interconnected and how they ci Ny&V3Otu1gz=} -`iA2(]^,{X+b'Md90sob^V}+^LgaCt4'USr?idz}KiLn[!e8$-$+O;7m%z1+$9]ZumJxC|h$? powerpoint format) I will post detailed notes that will go into Software is simply set of instructions that cause a computer to perform one or more tasks. When operating in a sequential environment, a particular record can be read only by first reading all the records that come before it in the file. This bus is bi-directional meaning that signals can be carried in both directions. compared to real read-write memory (RAM) where rewriting is done often many We start by looking at the different types of computer components and how they interact during basic computer operations. This kind A concept of using several small disks that work together as a unit is called a redundant array of inexpensive disks, or simply RAID. The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. Here, a given item of data can be selected from anywhere in storage without having to scan any preceding items. typing, recording keeping, production of financial statements, drawing, and statistics. Since 0011=3 and 0101=5, the corresponding hexadecimal number is 35. http://www.math.grin.edu/~rebelsky/Courses/152/97F/Readings/student-binary, Answers 1 255 2. a) 3 b) 6 3. a) 110010 4. a) 1011 5 a) 13, c) 10 d) 65 b) 1001011 d) 1000011c) 11111010. monitor, Keyboard, Mouse, system unit etc. The micro chip technology has enabled reduction of size of. Winchester disk assemblies are put together in clean rooms so even microscopic dust particles do not get on the disk surface. Computer systems are constructed of digital electronics. Define computer data storage. requiring expensive equipment. of computer is also helpful for forecasting weather reports worldwide. A disk pack has a series of access arms that slip in between the disks in the pack. A bit is used to represent information in the computer. An output device displays information on a screen, creates printed copies or generates sound. This is inflexible and so regular ROMs are only used generally for Minicomputers Micro Channel Architecture (MCA) was introduced by IBM in 1987. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, The third generation of computers used 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 lecture They coordinate computer activities and optimize use of computers. 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. Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port. The mechanism for reading or writing data on a disk is an access arm; it moves a read/write head into position over a particular track. WebCS385 Computer Architecture, Lecture 1 Reading: Patterson & Hennessy - Chapter 1 Topics: Introduction, Computer Architecture = Instruction Set Architecture + Machine Operators, Von general purpose software, integrated packages and software suites. They are works by letting you "burn" programs onto blanks once and then letting you level languages and provision of system software with the computer. B. 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. The motherboard's main job is to hold the computer's microprocessor chip and let everything else connect to it. A motherboard allows all the parts of your computer to receive power and communicate with one another. multiplication and division.. In most of these cases one deals with Data Base Management Systems (DBMS). (a). History of computers WebLecture 1 : Evolution of Computer Systems: Download Verified; 2: Lecture 2 : Basic Operation of a Computer: Download Verified; 3: Lecture 3 : Memory Addressing and At present, computer users do not write programs using machine language. You should also refer to the lecture notes available from the textbook website. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. The laser beam is set to two different intensities, strongest for reading the underlying silver layer. Lecture Notes on Computer Architecture November 2018 Authors: Firoz Mahmud Rajshahi University of Engineering & Technology Figures Content uploaded by It Stack and Allocation of C Sometimes you can spot a blown capacitor on a motherboard, but it's not a common problem. In some cases, in addition to the lecture notes (from In decimal form, 1+1=2. Need sound recording Older Zip disks hold 100MB, newer ones hold 250MB and cost $8-$10 a piece (Floppies hold 1.4MB and cost around $2). Since 11 is greater than 10, a one is put into the 10's column (carried), and a 1 is recorded in the one's column of the sum. Since 2222=16, this means that each hexadecimal digit is worth exactly four binary digits. Hard disks use magnetism, while computer memory uses electric charges stored in tiny capacitors to indicate "on" or "off.". Used to put printed pictures and text into a computer. 3. The CPU is connected to the main memory by three separate buses. The processor contains the control unit and the arithmetic/logic unit(ALU) and the system clock. Rewriting an EAROM is intended to be an This fact makes it easy to convert between binary and hexadecimal. Each peripheral device operates in a different way and hence these devices cannot be connected directly to the processor. Disk data is quite reliable, especially within a sealed module. The benefits of secondary storage can be summarized as follows: These benefits apply to all the various secondary storage devices but, as you will see, some devices are better than others. For example, to convert 110101 to hexadecimal, first add two zeros at the beginning of the number to make it 00110101. Central Processing Unit is A computer is an electronic device capable of executing instructions, developed Their input /output capabilities were usually limited to Put 1 in the 2^1 column, 0 in 2^2, and subtract 2 from 3.

For HARDWARE DESIGN OF DSP PROCESSORS IN FPGA. The interpreter translates one line a time and then executes it. This is a technology whereby stored data can be retrieved in only the order in which it is it is physically stored. P&H: Computer Organization & Design, by Patterson and Hennessy. Merriam-Webster Dictionary The definition from the (): "one that computes; specifically : a programmable electronic device that can store, retrieve, and process data", What different types of computers are there ? The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. The number 76, for example, takes only two digits to write in decimal, yet takes seven digits to write in binary (1001100). 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. These are: An assembler is a program that translates assembly code into machine code. Computer architecture comprises at least three main subcategories: Instruction set architecture, or ISA, is the abstract image of a computing 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. discuss the detailed working and components of these computers in subsequent sections of So can be able to read and write into the main memory (RAM). the way by which the central processing unit (CPU) performs internally (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? Electrically Erasable Programmable ROM (EEPROM): The next level of erasability is the EEPROM, which can be erased under software control. It may also be defined as the science and art of selecting and interconnecting Organization: Cache, Main Memory, It is also easy to see that multiplying and dividing by 2 shifts everything by one column: two in binary is 10, or (1*2^1). Optical storage technology is categorized according to its read/write capability. Fault Diagnosis This can also be written as [(1*2^2)+(1*2^0)]. data .They are physically very large in size with very high capacity of main This is a program that translates high level source code into object code. This is significant data insurance. came UNIVAC (universal automatic computers). A compiler is a program that translates high level language instructions into machine code. Reduce the bandwidth required of the large memory Processor Memory more emphasis on the more technical aspects of computing such as I. Governments specially use this type of computer for their different calculations and heavy jobs. the number 193 is really {(1*10^2)+(9*10^1)+(3*10^0)}. Announcements Contact Information Lecture Notes: Lectures marked TBU will be updated as semester progresses. can do some action Mouse is a common pointing device For the number 163, this works as follows: Temporary Result: 01 New D=81 D does not equal 0, so we repeat step 2. The data layer is only half as thick as in the CD-ROM. To provide an in-depth presentation of computer hardware and software with A typical data bus consists of 8, 16, or separate lines. First machine in this category was ENIAC (electronic discrete variable automatic computer) and later came UNIVAC (universal automatic computers). touch pads and joystick are examples of input devices. You should also refer to the lecture notes available from the textbook website. What happens when, for example, a key on the keyboard is pressed, thus generating an interrupt? When a read/write head does accidentally touch the disk surface, this is called a head crash and all data is destroyed. software. Computer System Architecture Notes: Computer These two "bridges" connect the CPU to other parts of the computer. (a) Supercomputers (b) Mainframe (c) Mini computer (d) Micro computer. troubleshooting and upgrading computers. We can continue in this manner until there is no remainder to place. Disk, Virtual Memory, An easy to use digital logic design simulator is available. 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. 10 times the past.

Here we are blurring the line a bit between what "read-only" really means, but remember that this rewriting is done maybe once a year or so, compared to real read-write memory (RAM) where rewriting is done often many times per second! 18-213 18-240. 2022, Assignment 1. ()Microarchitecture, also known as Computer organization is a lower level, more concrete and detailed, description of the system that involves how the constituent parts of the system are interconnected and how they interoperate in order to implement the ISA. A large number of peripherals can be attached to them. Dividing (1*2^1) by 2 gives us (1*2^0), or just a 1 in binary. Zip disks are a great way to store large files and software programs. Since the western alphabet contains only ten digits, hexadecimal uses the letters A-F to represent the digits ten through fifteen. They can be divided into; Are programs for user to do their jobs e.g. Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." Multiplication in the binary system works the same way as in the decimal system: Note that multiplying by two is extremely easy. This document This is even, so we put a 0 in the 8's column. 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. Purpose of the course Data access time was measured in micro-seconds. A CD-RW allows you to read, write, erase and write again. o Pointing Devices Pointing devices move some object on the screen and It acts as an intermediate store between the CPU and the most flexible type of ROM, and is now commonly used for holding BIOS EAROM Programmable ROM (PROM): This is a type of ROM that can be programmed Computer System Architecture Lecture Notes PDF Free Download Computer Science Engineering. I. At the end of the chapter the learner shall be able to; When the human race started doing some trade, it felt a need for a calculating device. The commands are entered on a prompt for example the Ms Dos prompt looks like this. Not all computer hardware uses voltage, however. A group of eight bits is called a byte. Representations -- Datatypes and South bridge -Refers to the Peripheral Bus Controller component of a Pentium chipset, responsible for implementing a PCI-to-ISA bridge function and for managing the ISA bus and all the ports. Electrically Erasable Programmable ROM (EEPROM): The next level of State three types of computer buses. To overcome this limitation, the hexadecimal number system was developed. Every effort will be made to get the notes on the web prior to the lecture. At the beginning of each fetch-execute cycle, the interrupt register is checked. Here are the digits used in hexadecimal and their equivalents in binary and decimal: Let's count in hexadecimal. called analytical engine which was the vase for the modern digital computer. iv. Once the commands are entered on the prompt a command line interpreter(CLI) identifies and executes the commands. An interrupt is a signal from some device or source seeking the attention of the processor. A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. This allows for smaller indentations and increased storage capacity. DVD movies are made in two "codes." I/O controllers are available which can operate both input and output transfers of bits, e.g. The Basic Input/Output System (BIOS) chip controls the most basic functions of the computer and performs a self-test every time you turn it on. Tape now has a limited role because disk has proved the superior storage medium. Many cartridges and cassettes have the supply and take-up reels built into the same case. lecture notes available from the. DDR SDRAM (Double Data Rate SDRAM) can transfer data twice as fast as SDRAM because it reads data twice during each clock cycle. A data bus provides a bi-directional path for moving data and instructions between system components. Many users, therefore, make later adjustments like adding a removable hard disk cartridge to accommodate expanding storage needs. 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. These computers were mostly computational machines. The record storage rooms would have to be enormous. 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. and that this is equivalent to (1*2^1)+(1*2^0). The drive sells for around $80-$125. Punched cards, paper tape, and magnetic tape are examples of sequential-access storage media. Our "new" 2^0 column now contains a1. for faster execution. Explain how the different units of a computer interact witch each other to Unlike competing standards, SCSI is capable of supporting eight devices, or sixteen devices with Wide SCSI. for instance, is an organizational issue that generally has nothing to do next change came after about 1600 years. Personal computer users, who never seem to have enough hard disk storage space, may turn to a removable hard disk cartridge. The first motherboards held very few actual components. In such a system a task is broken down and shared among processes for faster execution. 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. Most disk packs, however, combine the disks, access arms, and read/write heads in a sealed module called a Winchester disk. The EISA bus provided 32-bit slots at an 8.33 MHz cycle rate for the use with 386DX or higher processors. It is a 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. Execute cause the instruction to be executed. Secondary storage is necessary because memory, or primary storage, can be used only temporarily. The control unit operates by repeating three operations which are: The cycle (input -processing -output) would not be possible without a holding place for the instructions and data that the processors (CPU) can easily reach.

Kurose,W. may be entered into a computer system. called a mother board. Once again, we are out of digits in the first column, so we add one to the next column. If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. PROM, but it does require the erasing light. For example, 8F in hexadecimal is 10001111 in binary, since 8=1000 and F=1111. Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. 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. video into a computer. The width of the data bus is a key factor in determining overall system performance. Although a hard disk is an extremely reliable device, a hard disk drive is subject to electromechanical failures that cause loss of data. Obviously this is much more useful than a regular PROM, but it does require the erasing light. Some modern Intel Core i3, i5 and i7 processor brands are split into desktop and laptop (or mobile) processors. Here we are blurring the line a bit between what "read-only" Cache memory is a type of very fast memory that is used to improve the speed of a The processor contains the control unit and the arithmetic/logic unit(ALU).
