  • 1 Metric Prefixes 2 Bits, Bytes, Nibbles, and Pixels
    Here are some terminologies relating to computing hardware, etc. 1 Metric prefixes Some of these prefix names may be familiar, but here we give more extensive listings than most people are familiar with and even more than are likely to appear in typical computer science usage. The range in which typical usages occur is from Peta down to nano or pico. A further note is that the terminologies are classicly used for powers of 10, but most quantities in computer science are measured in terms of powers of 2. Since 210 = 1024, which is close to 103, computer scientists typically use these prefixes to represent the nearby powers of 2, at least with reference to big things like bytes of memory. For big things: Power In CS, Place-value Metric metric of 10 may be name prefix abbrev. 103 210 thousands kilo k 106 220 millions mega M 109 230 billions giga G 1012 240 trillions tera T 1015 250 quadrillions peta P 1018 260 quintillions exa E 1021 270 sextillions zeta Z 1024 280 septillions yotta Y For small things: Power In CS, Place-value Metric metric of 10 may be name prefix abbrev. 10−3 2−10 thousandths milli m 10−6 2−20 millionths micro µ 10−9 2−30 billionths nano n 10−12 2−40 trillionths pico p 10−15 2−50 quadrillionths femto f 10−18 2−60 quintillionths atto a 10−21 2−70 sextillionths zepto z 10−24 2−80 septillionths yocto y 2 Bits, bytes, nibbles, and pixels Information in computers is essentially stored as sequences of 0's and 1's.

  • BCA SEM II CAO Data Representation and Number System by Dr. Rakesh Ranjan .Pdf.Pdf
    Department Of Computer Application (BCA) Dr. Rakesh Ranjan BCA Sem - 2 Computer Organization and Architecture About Computer Inside Computers are classified according to functionality, physical size and purpose. Functionality, Computers could be analog, digital or hybrid. Digital computers process data that is in discrete form whereas analog computers process data that is continuous in nature. Hybrid computers on the other hand can process data that is both discrete and continuous. In digital computers, the user input is first converted and transmitted as electrical pulses that can be represented by two unique states ON and OFF. The ON state may be represented by a “1” and the off state by a “0”.The sequence of ON’S and OFF’S forms the electrical signals that the computer can understand. A digital signal rises suddenly to a peak voltage of +1 for some time then suddenly drops -1 level on the other hand an analog signal rises to +1 and then drops to -1 in a continuous version. Although the two graphs look different in their appearance, notice that they repeat themselves at equal time intervals. Electrical signals or waveforms of this nature are said to be periodic.Generally,a periodic wave representing a signal can be described using the following parameters Amplitude(A) Frequency(f) periodic time(T) Amplitude (A): this is the maximum displacement that the waveform of an electric signal can attain. Frequency (f): is the number of cycles made by a signal in one second. It is measured in hertz.1hert is equivalent to 1 cycle/second. Periodic time (T): the time taken by a signal to complete one cycle is called periodic time.

  • Tutorial on the Digital SENT Interface
    A Tutorial for the Digital SENT Interface By Tim White, IDT System Architect SENT (Single Edge Nibble Transmission) is a unique serial interface originally targeted for automotive applications. First adopters are using this interface with sensors used for applications such as throttle position, pressure, mass airflow, and high temperature. The SENT protocol is defined to be output only. For typical safety-critical applications, the sensor data must be output at a constant rate with no bidirectional communications that could cause an interruption. For sensor calibration, a secondary interface is required to communicate with the device. In normal operation, the part is powered up and the transceiver starts transmitting the SENT data. This is very similar to the use model for an analog output with one important difference: SENT is not limited to one data parameter per transmission and can easily report multiple pieces of additional information, such as temperature, production codes, diagnostics, or other secondary data. Figure 1 Example of SENT Interface for High Temperature Sensing SENT Protocol Basic Concepts and Fast Channel Data Transmission The primary data are normally transmitted in what is typically called the “fast channel” with the option to simultaneously send secondary data in the “slow channel.” An example of fast channel transmission is shown in Figure 2. This example shows two 12-bit data words transmitted in each message frame. Many other options are also possible, such as 16 bits for signal 1 and 8 bits for signal 2. Synchronization/

John Tukey, a leading statistician and adviser to five presidents first used the term in 1946. A single bit can hold only one of two values: 0 or 1. More meaningful information is obtained by combining consecutive bits into larger units. For example, a byte is composed of 8 consecutive bits. Computers are sometimes classified by the number of bits they can process at one time or by the number of bits they use to represent addresses. These two values are not always the same, which leads to confusion. For example, classifying a computer as a 32-bit machine might mean that its data registers are 32 bits wide or that it uses 32 bits to identify each address in memory. Whereas larger registers make a computer faster, using more bits for addresses enables a machine to support larger programs.

  • Data Representation
    Data Representation Data Representation Chapter Three A major stumbling block many beginners encounter when attempting to learn assembly language is the common use of the binary and hexadecimal numbering systems. Many programmers think that hexadecimal (or hex1) numbers represent absolute proof that God never intended anyone to work in assembly language. While it is true that hexadecimal numbers are a little different from what you may be used to, their advan- tages outweigh their disadvantages by a large margin. Nevertheless, understanding these numbering systems is important because their use simplifies other complex topics including boolean algebra and logic design, signed numeric representation, character codes, and packed data. 3.1 Chapter Overview This chapter discusses several important concepts including the binary and hexadecimal numbering sys- tems, binary data organization (bits, nibbles, bytes, words, and double words), signed and unsigned number- ing systems, arithmetic, logical, shift, and rotate operations on binary values, bit fields and packed data. This is basic material and the remainder of this text depends upon your understanding of these concepts. If you are already familiar with these terms from other courses or study, you should at least skim this material before proceeding to the next chapter. If you are unfamiliar with this material, or only vaguely familiar with it, you should study it carefully before proceeding. All of the material in this chapter is important! Do not skip over any material. In addition to the basic material, this chapter also introduces some new HLA state- ments and HLA Standard Library routines. 3.2 Numbering Systems Most modern computer systems do not represent numeric values using the decimal system.

  • RS-232 Control of the Advantage PMX84
    RS-232 Control of the Advantage PMX84 ________________________________________________________________________________________ Biamp Systems, 14130 N.W. Science Park, Portland, Oregon 97229 U.S.A. (503) 641-7287 an affiliate of Rauland-Borg Corp. Introduction This document contains technical information relating to computer control of the Biamp Advantage PMX84 Programmable Matrix Switch. This information is intended for advanced users - in particular for those who wish to develop their own computer programs to control the PMX84. It is assumed that the reader is an experienced programmer and has some familiarity with standard programming practices, binary and hexadecimal numbers, the ASCII character set, asynchronous serial data communications, and RS-232 interfaces. Hexadecimal, ASCII-Hex, and "Pseudo-Hex" Numbers Throughout this document, hexadecimal numbers shall be represented by preceding the number with "0x". For example: the hexadecimal equivalent of the decimal number 255 is 0xFF. Individual ASCII characters, except control characters, will be enclosed in single quotes. For example: the ASCII character 'A' has the hexadecimal value 0x41. The ASCII "carriage return" control character shall be represented as . An ASCII code chart is included with this document for your convenience. When an 8-bit binary data value is being transmitted over a serial data communications link, it is a common practice to transmit the byte as two "ASCII-hex" characters - one character represents the most significant nibble of the data value and the other character represents the least significant nibble (a nibble is 4-bits; half of a byte). Each ASCII-hex character is in the range of '0' thru '9' or 'A' thru 'F' (from the ASCII code chart, 0x30 thru 0x39 or 0x41 thru 0x46).
