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. Diskettes and hard disks are magnetic media; that is, they are based on a technology of representing data as magnetized spots on the disk with a magnetized spot representing a 1 bit and the absence of such a spot representing a 0 bit. Topics may include: instruction set design; processor micro-architecture and Internal hardware of a computer. (Photo openphoto.net. Used with permission.) Examples operating systems that use command based interface are Ms Dos and Unix. to be reprogrammed again. Once again, we are out of digits in the first column, so we add one to the next column. xH2Z@Qh>$p+![r5V28U<>hc`Ko3e7F^(CRz.]kA/()U&JxQ*r"?Da:)oW6LW8it^0!m OzDH This generation marked the origin of mini computers in use today. Nguyen Quoc Trung. Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. Cache memory is a type of very fast memory that is used to improve the speed of a This is even, so we put a 0 in the 8's column. A command based interface is quick to operate and very flexible, but the user needs to learn all the commands and type them in correctly. Sometimes you can spot a blown capacitor on a motherboard, but it's not a common problem. Computer architecture comprises at least three main subcategories: Instruction set architecture, or ISA, is the abstract image of a computing interoperate in order to implement the ISA. Some systems feature dual BIOS, which provides a backup in case one fails or in case of error during updating. 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. and to perform computations on these measurements. The arithmetic/logic unit(ALU) plays two roles. Ultraviolet light of a specific frequency can be shined through this the lecture -- the notes posted here provide, in some cases, more Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be frequent and the mechanical desk calculator was developed around 1800 A. notes posted are not meant to substitute for the text Main Memory Invention of IC revolutionalised electronics and started the error of micro-electronics. Memory allocation: malloc and WebLecture notes of Prof David Brooks could also be referred. o Number of components in computer per circuit (IC) greatly increased over The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. When a read/write head does accidentally touch the disk surface, this is called a head crash and all data is destroyed.

These computers used transistors after invention of transistors. Next, add {(2+4) +1} (the one is from the carry)=7, which is put in the 10's column of the sum. Windows is a Graphical user interface based operating system. The definition from the Merriam-Webster Dictionary : "one that computes; specifically : a programmable electronic device that can store, For many applications, EAROM has been supplanted by CMOS RAM backed-up by a lithium battery. The normal number system we use is called the decimal or the denary number system. WebBIT 1101 Computer Architecture complete lecture notes for first years and all - P. Box 342-01000 - Studocu. HARDWARE DESIGN OF DSP PROCESSORS IN FPGA. advancement in computer architecture to current technologies erasability is the EEPROM , which can be erased under software control. infrequent operation - most of the time the memory is used as a ROM. The two components (hardware, software) will be discussed later in other Continuing the "CD" analogy, this 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. Obviously this is much more useful than a regular troubleshooting and upgrading computers. System Design which includes all of the other hardware components (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? 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! To multiply by two, just add a 0 on the end. hardware components to create computers that meet functional, performance At the end of the chapter the learner shall be able to; chapters. This kind In some cases, in addition to the lecture notes (from 1 Software and Hardware C. Characteristics of computers The methods we will consider here are the sector method and the cylinder method. a lithium battery. It has a grid of columns and rows with a cell that has two transistors at each intersection. Different industries also use this huge computer for computer can process 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. As you know, the decimal system uses the digits 0-9 to represent numbers. RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. Electrically Alterable Read-Only Memory(EAROMs) can be modified a bit at a time, but writing is a slow process and uses non-standard voltages (usually higher voltages around 12 volts). {HnzIxfjw^K](^$L The cylinder method, then, means all tracks of a certain cylinder on a disk pack are lined up one beneath the other, and all the vertical tracks of one cylinder are accessible by the read/write heads with one positioning of the access arms mechanism. Microarchitecture, also known as Computer organization is a lower level, (a) Supercomputers (b) Mainframe (c) Mini computer (d) Micro computer. While information retrieval is faster than from a floppy disk, it is still not as fast as from the hard drive. State and explain any five characteristics of storage. Although the EISA bus is backwards compatible and not a proprietary bus it never became widely used and is no longer found in computers today. (b) List four of the conditions an ALU tests for. 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. drive. A way to organize data on a disk pack is the cylinder method. Instruction set architecture System organization (processor, memory, I/O) Micro-architecture Learn methods of evaluating performance Metrics Benchmarks Learn how to make systems go fast Pipelining, caching Parallelism Learn how to make systems less power hungry (maybe) Once the commands are entered on the prompt a command line interpreter(CLI) identifies and executes the commands. Brooks, Planning a Computer System, Project Stretch, 1962 What does this design consist of? The speed of these machines was described in microseconds (1/1000, 000 of a second). Since Assembly language is machine dependent each type of computer has its own assembler. 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. A. A CD-R is a one time recordable compact disc. the manufacturer. The transistor is smaller cheaper and produced less heat than vacuum tubes and consumed less power. In most of the Hollywoods movies it is used for animation purposes. For example, a transistor with five volts would be considered "on", while a transistor with no voltage would be considered "off." However, this is not the only approach possible. What we're doing here is finding the largest power of two within the number (2^2=4 is the largest power of 2 in 5), subtracting that from the number (5-4=1), and finding the largest power of 2 in the remainder (2^0=1 is the largest power of 2 in 1). Large computers have dozens or ever hundreds of disk drives. (2mks) (b). the 0s and 1s with 0 representing an OFF state and 1 representing an ON state. Mainframe computers Personal computer users find accessing files on a hard disk is significantly faster and thus more convenient than accessing files on a diskette. Since the western alphabet contains only ten digits, hexadecimal uses the letters A-F to represent the digits ten through fifteen. This computer is not used as a PC in a home neither by a student in a Neumann Architecture Model and GCEa[i%kP0^; X2tLkcUe0HCT#h:+)^DQ .+Wap!kmb349!|n)\Pm6RhaXdl(h4~q!0ca,|"F]8^Y3Q/=w%SUlZyL Storage capacity was very low i.e. The records are read in sequence. This can also be written as [(1*2^2)+(1*2^0)]. Micro computers 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. Writing and understanding programs in assembly language is easier than that of machine language. Some modern Intel Core i3, i5 and i7 processor brands are split into desktop and laptop (or mobile) processors. Floppy Disk: Floppy disks allow information to be transported easily from one Memory size expanded up to several MB and speed was 10 times faster. A. Hard disk capacity for personal computers has soared in recent years; capacities of hundreds of megabytes are common and gigabytes are not unusual. 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. where each a[i] is either a 1 or a 0 (the only possible digits for the binary system). An interrupt is a signal from some device or source seeking the attention of the processor. The design of these computers was based on VLSI (very large scale integration) technology, the micro chip technology that gave rise to the smaller computers known as the micro computers in use today. Execute cause the instruction to be executed. To execute an assembly language program it should first be translates into an equivalent machine language program. WebComputer Architecture PPT Instructor Prof. Laxmi N. Bhuyan ( bhuyan@cs.ucr.edu) Main Text: Patterson and Hennessy, Computer Organization and Design, Morgan Kaufman They are more susceptible to physical damage and viruses than the hard drive. Try converting these numbers from binary to decimal: | | | 1 | 0 | | 1 | 1 | 1 1 | 0 | 1 | 0 | 1 1 | 1 | 1 | 1 | 0. microcomputer is called a microprocessor. 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. The system unit is often called the Central Processing Unit. for using the C to LC3 9 The DVD is a flat disk, the size of a CD -4.7 inches diameter and .05 inches thick. Consequently, the primary role of tape today is as an inexpensive backup medium. humans. design and fundamental operational structure of a computer system. keyboard controller or as output controller, e.g. In assembly language mnemonic codes are used to develop program for problem solving. Software: Categories of software, System software, applications software, 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. a similar course at Univ. 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. They can be linked to smaller The following program written in BASIC language is to add two given numbers. ()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. the micro era based on large scale integration that confines several physical components per small elements thumb size IC, hence the size reduced. The processor and main memory of a PC are commonly held on a single board DVD movies are made in two "codes." Motherboard failures usually show up as second level problems, like "I've replaced the video card and the screen is still dead." Computers have continued to decrease in size but the processing power has Chapter 4 (Processor Architecture) 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. Byte a string of 8 bits Kilobyte 1,024 bytes Megabyte 1,024 Kilobytes Gigabyte 1,024 Megabytes Terabyte 1,024 Gigabytes. class. the required results faster than human beings. There are different types of disk packs, with the number of platters varying by model. the number 193 is really {(1*10^2)+(9*10^1)+(3*10^0)}. Thus, our number is 1001011. It is designed to perform a specific function and cannot be changed. to the C language (part 1/2), Introduction very low i. Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." Continue counting: 10, 11, 12, 13, 14, 15, 16, 17 18, 19, 1A, 1B, 1C, 1D, 1E, 1F. programs. notes posted are a superset of what I will go over during Fault Diagnosis and cost goals. Eight's column: We can divide by two again to get 20. A byte can hold 28 different combinations of 0s and 1s, which means that for example, 256 different characters can be represented. Super computers are biggest in size, the most expensive in price than any other is retrieve, and process data", What different types of computers are there? For The high level languages commonly used are FORTRAN (FORmula TRANslation), BASIC (Beginner's All-purpose Symbolic Instruction Code), COBOL (COmmon Business Oriented Language). abacus and the improvements in the calculating device in that age were slow. This process continues until we have a remainder of 0. ROM: A mask programmed read only memory that can be only be produced by 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. There are several specific form factors that most PC motherboards use so that they can all fit in standard cases.

Several disks can be assembled into a disk pack. Explain how the different units of a computer interact witch each other to details than what we will cover in the lecture. computers are mainly used for scientific and engineering applications. calculations and heavy jobs. Nederlnsk - Frysk (Visser W.), Applied Statistics and Probability for Engineers (Douglas C. Montgomery; George C. Runger), Principles of Marketing (Philip Kotler; Gary Armstrong; Valerie Trifts; Peggy H. Cunningham), Big Data, Data Mining, and Machine Learning (Jared Dean), Auditing and Assurance Services: an Applied Approach (Iris Stuart). must match the DVD region. 2 Input Devices 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). more detail than the book and you are expected to read them and read A motherboard allows all the parts of your computer to receive power and communicate with one another. This is similar to the way a CD-ROM recorder this unit. To understand binary numbers, begin by recalling elementary school math. These patterns of "on" and "off" stored inside the computer are used to encode numbers using the binary number system. This categories are based on size, price and capabilities. One idea is to "shift" them. 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). Thus, we would put a 1 in the 2^6 column, and subtract 64 from 75, giving us 11. Can hold up to 700MB of information. MCA, or the Micro Channel bus, was a competition for ISA bus. All the components in the computer share the data and address buses. Twelve would be 12*10^0, or 10^0(10+2), or 10^1+2*10^0, which also uses an additional column to the left (12). In effect, a removable cartridge is as portable as a diskette, but the disk cartridge holds much more data. Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. huge in size and occupy a room. Users plugged components like floppy drive controllers and ()memory into the slots. erased and reprogrammed. 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. They are very large in size and use multiple processors and superior technology. ); it can be written to, but only 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. 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). If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. time was measured in micro-seconds. They are of advanced technology i.e. companies, and many other huge companies prefer mainframe because of its give the user output WebCS 135: Computer Architecture I Fall 2010 Lecture Notes.
