1 Lecture 21: Software Architectures 21-architecture.ppt Author: Steve Easterbrook Created Date: Bus size means the number of bits that can be transmitted together. They can be divided into; Are programs for user to do their jobs e.g. 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. The fetch execute cycle xH2Z@Qh>$p+![r5V28U<>hc`Ko3e7F^(CRz.]kA/()U&JxQ*r"?Da:)oW6LW8it^0!m OzDH 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. The cost of computers decreased and the speed increased. Once the commands are entered on the prompt a command line interpreter(CLI) identifies and executes the commands. drive. 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. Computers have continued to decrease in size but the processing power has o Scanner allows you to scan documents, pictures, or graphics and view http://www.math.grin.edu/~rebelsky/Courses/152/97F/Readings/student-, L.N.Gumilyov Eurasian National University, Jomo Kenyatta University of Agriculture and Technology, Kwame Nkrumah University of Science and Technology, Introduction to Entrepreneurship (Introduction to Entr), Human Resource, Organizational Behavior, (HR, OB), Bachelor of science in accountancy (150062), FOUNDAMENTALS OF NURSING SCIENCE (NRSG 212), Geometrical Optics and Mechanics (PHY112), Avar Kamps,Makine Mhendislii (46000), Power distribution and utilization (EE-312). Arithmetic operations these operations are addition, subtraction, Representations -- Datatypes and To accommodate the increased speed, chip manufacturers have designed and built faster RAM chips. Flash memory is used for easy and fast information storage in computers, digital cameras and home video game consoles. Furthermore, memory is limited in size, whereas secondary storage media can store as much data as necessary. The EISA bus is found on Intel 80386, 80486 and early Pentium computers. An interrupt is a signal from some device or source seeking the attention of the processor. In some cases, in addition to the lecture notes (from This is mostly hard drives and removable media such as floppy disks, optical media (CD ROM) etc. II. ci Ny&V3Otu1gz=} -`iA2(]^,{X+b'Md90sob^V}+^LgaCt4'USr?idz}KiLn[!e8$-$+O;7m%z1+$9]ZumJxC|h$? 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. may be used to store critical system setup information in a non-volatile way. video recorder o Digital Camera Used to take electronic pictures of an object. Static RAM does not need to be refreshed, which makes it faster; but it is also more expensive than dynamic RAM. MCA, or the Micro Channel bus, was a competition for ISA bus. These computers used transistors after invention of transistors. hardware components to create computers that meet functional, performance Printout is permanent Power failure-initiated when a decline in the internal voltages is detected, giving the OS a few milliseconds to close down as gracefully as possible. The binary number system is a method of storing ordinary numbers such as 42 or 365 as patterns of 1's and 0's. At the end of the chapter the learner shall be able to; DDR SDRAM (Double Data Rate SDRAM) can transfer data twice as fast as SDRAM because it reads data twice during each clock cycle. Memory allocation: malloc and Many users, therefore, make later adjustments like adding a removable hard disk cartridge to accommodate expanding storage needs. Data are stored in a small indentation in a spiral track, just like in the CD. 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. Central Processing Unit is 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. This allows for smaller indentations and increased storage capacity. WebSymposium on Computer Architecture (ISCA), 1994 Lecture notes will be available in pdf and powerpoint formats, with 6 per page for pdf for conventinent printing.. (Powerpoint is for instructors who want to give lectures themselves based on CS 252.) 2. Almost all the computers used nowadays are digital computers and we will 2kb and speed of processing was also very low. Computer architecture or digital computer organization is the conceptual design and fundamental operational structure of a computer system. unit, memory (ROM, RAM). Some systems feature dual BIOS, which provides a backup in case one fails or in case of error during updating. 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. Neumann Architecture Model and But this is not practical for a system with many files or many users. An input device lets you communicate with a computer. Disk data is quite reliable, especially within a sealed module. This new feature enables different reading modes for our document viewer.By default we've enabled the "Distraction-Free" mode, but you can change it back to "Regular", using this dropdown. Record the 0, carry the 1. gigabytes. 6.823 is a study of the evolution of computer architecture and the factors influencing the design of hardware and software elements of computer systems. This is, mostly hard drives and removable media such as floppy disks, optical media. The small circuitry that resulted improved the processing speed i.e. A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. All the components in the computer share the data and address buses. A monitor, printer, and speakers are examples of output devices. The control unit operates by repeating three operations which are: Fetch cause the next instruction to be fetched from memory; c l oc k , registers Word size also determines the speed of the computer. Many cheaper PC's ship with power supplies I would basically describe as "disposable." When we talk about troubleshooting video failures, we're usually talking about no image at all on the screen. the maim memory, and works by storing the most frequently or recently used instructions A large number of keyboard controller or as output controller, e.g. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. The first in the Windows series was Windows 3.11 and the latest being Windows Vista. Assembly language is translated into machine code using an assembler before they can be executed. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. Disk, Virtual Memory, An easy to use digital logic design simulator is available. modes, processor registers, and address and data formats. These are devices which are used to store huge information for future use. (c) Explain the use of registers in the CPU. Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components. The processor contains the control unit and the arithmetic/logic unit(ALU) and the system clock. Pages 4-. increased. compared to real read-write memory (RAM) where rewriting is done often many A set of programs associated with the operation of a computer. 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. Each disk in the pack has top and bottom surfaces on which to record data. Computers, in contrast, permit storage on tape or disk in extremely compressed form. general purpose software, integrated packages and software suites. power. The cost of computers decreased and the speed increased. Using a method called helical scan recording, DAT wraps around a rotating read/write head that spins vertically as it moves. Data access times per second! 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. We can continue in this manner until there is no remainder to place. Computers cannot do any useful work without instructions from software; thus a combination of software and hardware (the computer) is necessary to do any computerized work. Windows is a Graphical user interface based operating system. Different industries also use this huge computer for Electronic memory comes in a variety of forms to serve a variety of purposes. Temporary Result: 01; Carry: 1, Column 2^2: 1+0=1 Add 1 from carry: 1+1=10. Furthermore, data security is improved because if a disk fails, the disk system can reconstruct data on an extra disk; thus, computer operations can continue uninterrupted. Consequently, the primary role of tape today is as an inexpensive backup medium. The lecture notes posted are not Mainframe computers The second generation saw the introduction of more complex ALU and CPU, the use of high level languages and provision of system software with the computer. The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. a similar course at Univ. -- you are required to read the textbook before (and after) each class. This is inflexible and so regular ROMs are only used generally for peripherals can be attached to them. Two reels are used, a supply reel and a take-up reel. Rewriting an EAROM is intended to be an infrequent operation -most of the time the memory is used as a ROM. The size of a hard drive is usually expressed in terms of megabytes and The fact that a disk is circular presents a problem: The distances around the tracks on the outside of the disk are greater than that of the tracks or the inside. To execute an assembly language program it should first be translates into an equivalent machine language program. o Speakers Used to output sound 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. This is useful for companies that make their own ROMs from software they write, because when they change their code they can create new PROMs without requiring expensive equipment. III. The hard disks are being improved as rapidly as DVD, and they definitely offer the fastest seek time and transmission rate (currently 5-10 MB/second). 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. B. Commands tell the computer In Fig 1.2, the notches we have marked as A, are used for the ejector clip on the DIMM slot (see later). The first place to start is always confirming that the power supply is operating properly. The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. III.

In some disk drives the access arms can be retracted; then the disk pack can be removed from the drive. Information is stored in computers in the form of bits. Power Supply Troubleshooting lecture notes available from the. 2022, Assignment 1. Therefore, it would shift you one column to the left. computer doubling it in some cases. Intro to LC3, Low-level These two "bridges" connect the CPU to other parts of the computer. 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. C. The motherboard; form factor, sockets and slots WebH&P2: Computer Architecture: A Quantitative Approach, 2nd edition, by Hennessy and Patterson. The data is recorded on the tracks that can be accessed by one positioning of the access arms-that is, on one cylinder. They made use of vacuum tubes to store and process information. Furthermore, data files, particularly those accessed by several users, are subject to errors introduced by users. drive. However, this is not the only approach possible. Then, replace each block of four digits with its corresponding hexadecimal digit. Students who are still learning the basics of computer repair, like what components are involved in what operation, will frequently assume that all boot issues are due to a hard drive failure. ROM: A mask programmed read only memory that can be only be produced by As you know, the decimal system uses the digits 0-9 to represent numbers. P.O. We begin with a look at the various storage media, including those used for personal computers, and then consider what it takes to get data organized and processed. Software: Categories of software, System software, applications software, Computer architecture or digital computer organization is the conceptual Older Zip disks hold 100MB, newer ones hold 250MB and cost $8-$10 a piece (Floppies hold 1.4MB and cost around $2). In decimal form, 1+1=2. To multiply by two, just add a 0 on the end. The largest power of 2 in 11 is 8, or 2^3. 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 State and explain any five characteristics of storage. To converty from binary to hexadecimal, reverse the procedure and break the binary number into blocks of four digits. 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. In fact, flash memory is known as a solid state storage device, meaning there are no moving parts --everything is electronic instead of mechanical. ); it can be written to, but only 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. The size of a hard drive is usually expressed in terms of megabytes and gigabytes. this unit. Each peripheral device operates in a different way and hence these devices cannot be connected directly to the processor. 2. contains materials that are frequently examined. Hard Drive: computers are mainly used for scientific and engineering applications. Output Electrically Erasable Programmable ROM (EEPROM): The next level of erasability is the EEPROM, which can be erased under software control. Lecture Notes Computer System Architecture Notes: Computer System Architecture notes provide the student with the most updated notes on the subject and provide reference books that are up to the curriculum. These notes are easy to interpret for aspiring students and are the best set of references for computer system architecture during revision. Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. The CPU and the RAM are two main components that can be upgraded to increase a computer's speed, though doing this may require replacing the motherboard as well. Particularly step 3, "filling in the zeros." As in other magnetic media, data is stored as extremely small magnetic spots. To understand binary numbers, begin by recalling elementary school math. The records are read in sequence. The commands are entered on a prompt for example the Ms Dos prompt looks like this. the 0s and 1s with 0 representing an OFF state and 1 representing an ON state. The movies are made in two formats, each with their own coding. For example, "3" in binary cannot be put into one column. A data bus provides a bi-directional path for moving data and instructions between system components. Most mainframe computers have 32-bit words. very low i. i.e., the programs were machine dependent. the micro computers are usually described as PCs or stand alone or desktop computers because they were designed primarily to serve single person at a time. Not all computer hardware uses voltage, however. Obviously this is much more useful than a regular (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices Other controllers operate in one direction only, either as an input controller, e.g. came UNIVAC (universal automatic computers). The purpose of the control bus is to transmit command , timing and specific status information between system components such as the memory, processor, keyboard input controller VDU output controller and the Disk I/O controller. All the tracks thus encountered, in the same position on each disk surface, comprise a cylinder. Data thus saved can be restored to the hard disk later if needed. written and quite useful -- they were written by the instructor for 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. The processor has the following functions: The control unit coordinates and controls all the operations carried out by the computer. Therefore, there must be a 0 in the 4's column, (because what we are actually placing is a 2^0 column, and the number is not odd). Temporary Result: 11 New D=40 D does not equal 0, so we repeat step 2. Control signals are sent along the control bus. Since we already knew how to convert from binary to decimal, we can easily verify our result. 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." Hardware and software Storage technologies at all levels of the storage hierarchy can be differentiated by evaluating certain core characteristics as well as measuring characteristics specific to a particular implementation. Many disk devices, however, do not record data on the top of the top platter or on the bottom of the bottom platter. The EISA bus provided 32-bit slots at an 8.33 MHz cycle rate for the use with 386DX or higher processors. This is inflexible and so regular ROMs are only used generally for programs that are static (not changing often) and mass-produced. In order to execute a high-level language program, it should be translated into a machine language either using a compiler or interpreter. Knowledge Network of Toyota. The form factor is just one of the many standards that apply to motherboards. 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. I/O controllers are available which can operate both input and output transfers of bits, e.g. 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. A motherboard by itself is useless, but a computer has to have one to operate. and to perform computations on these measurements. They are slower and less costly compared to mainframe computers but more powerful, reliable and expensive than micro computers. the keyboard and or punched card input and printer and or punched cart output. Includes the semester schedule and a complete set of PowerPoint lecture notes and associated code, updated for CS:APP3e. It can process trillions of instructions in erased and reprogrammed. A network operating system is required when a number of computers are connected together to form a network. The IBM 360 is an example of third generation computers. Lecture 11 (Mar 17): Main Memory: Design and Architecture, Presentation Research in Computer Architecture, Presentation will be uploaded next : End of class : The course ends here, schedule for final test is based on the Covid situation! If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. To convert the decimal number 75 to binary, we would find the largest power of 2 less than 75, which is 64. Unlike competing standards, SCSI is capable of supporting eight devices, or sixteen devices with Wide SCSI. The tubes The size of a computer's cache for instance, is an organizational issue that generally has nothing to do with the ISA. Operating systems(OS) acts as an interface between the computer hardware and the computer user and manages the whole computer system. It acts as an intermediate store between the CPU and HARDWARE DESIGN OF DSP PROCESSORS IN FPGA. 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). Subroutines, Solution to Vector Inner (Dot) more detail than the book and you are expected to read them and read Software Computer systems are constructed of digital electronics. Since 00110101 has eight digits, it can be divided into two blocks of four digits, 0011 and 0101. 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. They are more susceptible to physical damage and viruses than the hard drive. and data so that it will be very fast to retrieve them again. The processor can read and write into the secondary storage devices. The truth is, of all the four subsystems represented in this table, hard drives are probably the most reliable. The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. To appreciate this, suppose you had an empty disk pack on which you wished to record data. A. calculations and heavy jobs. Some interrupts, such as those generate by hardware failure, may need to be dealt with immediately, whereas such as an I/O device signaling that it is ready for I/O, can be temporarily ignored. to read the textbook and, preferably, the posted notes before coming to class. process millions of instruction per second and capable of accessing billions of frequent and the mechanical desk calculator was developed around 1800 A. (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. Word size means the number of Bits that the processor can process simultaneously. These are devices which are used to store huge information for future use. touch pads and joystick are examples of input devices. When you hear reference to a "flash BIOS" or doing a BIOS upgrade by "flashing", this refers to reprogramming the BIOS EEPROM with a special software program. humans. Decode translate the program instruction into commands that the The easy cases to diagnose are those where the monitor or LCD isn't powering up properly, or the PC not powering up. The micro chip technology has enabled reduction of size of. This places the data in diagonal bands that run across the tape rather than down its length. The methods we will consider here are the sector method and the cylinder method. The shape and layout of a motherboard is called the form factor. Take the number 163. Next, we focus specifically on the CPU (Central Processing Unit). Perhaps more important than capacity, however, is the convenience of speed. to the C language (part 2/2), Run-time Hardware: input and output devices, backup storage, central processing In binary, any digit higher than 1 puts us a column to the left (as would 10 in decimal notation). The high level languages commonly used are FORTRAN (FORmula TRANslation), BASIC (Beginner's All-purpose Symbolic Instruction Code), COBOL (COmmon Business Oriented Language). once. System Design which includes all of the other hardware components It interprets the instructions in the program and executes one by one. At present, computer users do not write programs using machine language. This method produces high density and faster access to data. give the user output seconds. the capacity to hold significantly more data than a 5-1/4 inch diskette. 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. works by letting you "burn" programs onto blanks once and then letting you 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. It is designed to perform a specific function and cannot be time was measured in micro-seconds. Explain the characteristics of computers and how they are different from I. with the ISA. A different ISR is provided for each different source of interrupt. Record the 11. The input and output devices are discussed in details in chapter 2 of the module.

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. The set of instructions is often called a program or, if the set is particularly large and complex, a system. FACE RECOGNITION AND SIMILAR, Structure and Interpretation of Computer Programs, TEXTURE ANALYSIS USING SPECTRAL TRANSFORMS. Dividing 80 by 2 gives 40. 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.

Motherboard and CPU Troubleshooting A bit is used to represent information in the computer. interoperate in order to implement the ISA. A mainframe is another giant computer after the super computer and can also Punched cards, paper tape, and magnetic tape are examples of sequential-access storage media. Although an individual probably cannot imagine generating enough output-letters, budgets, reports, and so forth-to fill a hard disk, software packages take up a lot of space and can make a dent rather quickly. When you start troubleshooting a dead computer, never ignore the possibility that the AC power to the PC's power supply is at fault. There are different types of disk packs, with the number of platters varying by model. 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. At the end of the chapter the learner shall be able to; 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. This categories are based on size, price and capabilities. Chapter 3- Instruction Winchester disk assemblies are put together in clean rooms so even microscopic dust particles do not get on the disk surface. Furthermore, graphics images and audio and video files require large file capacities. However, the amount of time it takes to access a record is dependent to some extent on the mechanical process involved. 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.
