to be reprogrammed again. Alternatives such as Zip disks (discussed later), or transferring data via networks are making the low-capacity diskette become obsolete. 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. Dynamic RAM needs to be refreshed thousands of times per second. interprets the instructions in the program and executes one by one. Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components. In binary, any digit higher than 1 puts us a column to the left (as would 10 in decimal notation). Computer systems are constructed of digital electronics. Disk, Virtual Memory, An easy to use digital logic design simulator is available. 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. In assembly language mnemonic codes are used to develop program for problem solving. The real time clock chip is a battery-operated chip that maintains basic settings and the system time. % smaller cheaper and produced less heat than vacuum tubes and consumed less Generations of computers Nederlnsk - Frysk (Visser W.), Applied Statistics and Probability for Engineers (Douglas C.

The second For the number 163, this works as follows: Temporary Result: 01 New D=81 D does not equal 0, so we repeat step 2. DVD disks are read by a laser beam of shorter wave-length than used by the CD ROM drives. Explain the different storage units of a computer such as byte, Kilobyte, Hardware units (Devices) of a computer can be categorized into five units; notes that you will be expected to read before class. Each disk in the pack has top and bottom surfaces on which to record data. Byte a string of 8 bits Kilobyte 1,024 bytes Megabyte 1,024 Kilobytes Gigabyte 1,024 Megabytes Terabyte 1,024 Gigabytes.

You should also refer to the lecture notes available from the textbook website. programs that are static (not changing often) and mass-produced. to read the textbook and, preferably, the posted notes before coming to class. give the user output In the sector method each track is divided into sectors that hold a specific number of characters. It may also be defined as the science and art of selecting and interconnecting hardware components to create computers that meet functional, performance and cost goals. A byte can hold 28 different combinations of 0s and 1s, which means that for example, 256 different characters can be represented. Prepare an oral presentation of approximately 25 min. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. 1 Lecture 21: Software Architectures 21-architecture.ppt Author: Steve Easterbrook Created Date: 2 Central Processing Unit (CPU)/Processor: It is the main part of a computer system like the brain of a human being.

A single bit alone cannot represent a number, letters or special characters, to represent information; bits are combined into groups of eight. Hard disks come in a variety of sizes. As in other magnetic media, data is stored as extremely small magnetic spots. Rewriting an EAROM is intended to be an You are required to Try converting these numbers from binary to decimal: | | | 1 | 0 | | 1 | 1 | 1 1 | 0 | 1 | 0 | 1 1 | 1 | 1 | 1 | 0. Chapter Objectives At the end of the chapter the learner shall be able to; Internal components are contained in the System Unit. It is the main part of a computer system like the brain of a human being. 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. To quote many a computer user, "I just couldn't envision how I could use all that disk space. ROM package, through which you can actually see the chip that holds the Please note the direction of the arrows as it depicts the flow of the data and instructions. Since 00110101 has eight digits, it can be divided into two blocks of four digits, 0011 and 0101. A network operating system is required when a number of computers are connected together to form a network. Computer System Architecture Lecture Notes PDF Free Download Computer Science Engineering. 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. Our "new" 2^0 column now contains a1. The size of a computer's cache for instance, is an organizational issue that generally has nothing to do with the ISA. C. Characteristics of computers A monitor, printer, and speakers are examples of output devices. This demanding shopping list is a description of the optical disk, like a CD. WebBIT 1101 Computer Architecture complete lecture notes for first years and all - P. Box 342-01000 - Studocu. Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." Each peripheral device operates in a different way and hence these devices cannot be connected directly to the processor. These patterns of "on" and "off" stored inside the computer are used to encode numbers using the binary number system. Consider the addition of decimal numbers: We begin by adding 3+8=11. This generation marked the origin of mini computers in use today. Use to put Personal computer users find accessing files on a hard disk is significantly faster and thus more convenient than accessing files on a diskette. Central processing unit (CPU) or processor taken by a digital camera can be used directly by a computer reliable and expensive than micro computers. There is more than one way of physically organizing data on a disk. They have higher main memory capacity, reliable and increased processing power (have the capability of holding more than one set of instructions and operate on them) than the second generation computers. Temporary Result: 1; Carry: 0, Column 2^1: 1+1=10. A binary digit (1 or 0) is known as a BInary digiT which in short is a bit. 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. works by letting you "burn" programs onto blanks once and then letting you The program given below shows assembly language program to add two numbers A & B. Applications software packages sometimes include a dozen diskettes or more; all these could fit on one optical disk with plenty of room to spare. Consists of programs that control operations of the computer and enable user to make efficient use of computers. Word size also determines the speed of the computer. The cost of computers decreased and the speed increased. where each a[i] is either a 1 or a 0 (the only possible digits for the binary system).

This process continues until we have a remainder of 0. Continuing the "CD" analogy, this The data in that memory location is then returned to the CPU on via the data bus. The pictures 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. Put 1 in the 2^3 column, and 0 in 2^4 and 2^5. The code written by the programmer is called the source code and the compiled code is called the object code. Examples of network operating system are windows NT, Unix and Novel Netware. 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. Power supplies often fail gradually, giving rise to symptoms that appear to be caused by individual component failure. They used magnetic tape. HARDWARE DESIGN OF DSP PROCESSORS IN FPGA. and cost goals. The form factor affects where individual components go and the shape of the computer's case. iv. Brooks, Planning a Computer System, Project Stretch, 1962 What does this design consist of? Winchester disk assemblies are put together in clean rooms so even microscopic dust particles do not get on the disk surface. this unit. Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. They are used for complex tasks requiring a lot of This places the data in diagonal bands that run across the tape rather than down its length. A computer is an electronic device capable of executing instructions, developed Computer hardware refers to the physical components of a computer such as the power. drive. erased and reprogrammed. For example, to convert 110101 to hexadecimal, first add two zeros at the beginning of the number to make it 00110101. 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. by "flashing", this refers to reprogramming the BIOS EEPROM with a special They are This is significant data insurance. process millions of instruction per second and capable of accessing billions of The programs written in assembly language are also machine dependent. When you start troubleshooting a dead computer, never ignore the possibility that the AC power to the PC's power supply is at fault. i.

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. For 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. The EISA bus provided 32-bit slots at an 8.33 MHz cycle rate for the use with 386DX or higher processors. These computers used transistors after invention of transistors. The system unit is often called the Central Processing Unit. All the components in the computer share the data and address buses. 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. A little glass window is installed in the top of the In other words, instead of columns being. Neumann Architecture Model and DVD movies are made in two "codes." Such a disk cannot, obviously, be used for your files, but manufacturers can use it to supply software. Four's column: Now we can subtract 1 from 81 to see what remainder we still must place (80). They are very large in size and use multiple processors and superior technology. To understand binary numbers, begin by recalling elementary school math. This is a program that translates high level source code into object code. Cache memory is a type of very fast memory that is used to improve the speed of a computer doubling it in some cases. write, because when they change their code they can create new PROMs without We can continue in this manner until there is no remainder to place. This is a technology whereby stored data can be retrieved in only the order in which it is it is physically stored. This change further decreased the size, heat output and the maintenance complexity of the computers while increasing its speed. Once the data has been processed by the processor, the data can be displayed by the output devices. Not all computer hardware uses voltage, however. WebLecture notes Chapters 1-3, 5-12 The CMU ICS+ coursethat covers everything in CS:APP3e except Chapter 4 (Processor Architecture). The speed of these machines was described in microseconds (1/1000, 000 of a second). The decimal number "2" is written in binary notation as "10" (1*2^1)+(0*2^0).
