  • Microprocessor 80386 Sx
    1,489 words
    The Evaluation of the Microprocessor. The microprocessor has changed a lot over the years, says (Michael W. Davidson, web) Microprocessor technology is progressing so rapidly that even experts in the field are having trouble keeping up with current advances. As more competition develops in this $150 billion a year business, power and speed of the microprocessor is expanding a tan almost explosive rate. The changes have been most evident over the last decade. The microprocessor has changed the wa...
  • Instruction Into The Coprocessors Memory
    2,986 words
    Floating Point Coprocessors The designer of any microprocessor would like to extend its instruction set almost infinitely but is limited by the quantity of silicon available (not to mention the problems of testability and complexity). Consequently, a real microprocessor represents a compromise between what is desirable and what is acceptable to the majority of the chip's users. For example, the 68020 microprocessor is not optimized for calculations that require a large volume of scientific (i.e....
  • 64 Bit Load And Store Risc Architecture
    2,225 words
    1. Investigate the instruction set and architectural features of a modern RISC processor such as the Digital Equipment Corporation Alpha or Motorola / IBM PowerPC. In what ways does it differ from the architecture of the Intel Pentium processor family The main difference between the architectures of Digital Equipment Corporation's (DEC) Alpha and Intel's Pentium processors are the instruction sets. In this paper I intend on defining both RISC and CISC processors. In doing this I will be comparin...
  • Good Implementation On 64 Bit Processors
    8,796 words
    Tomorrow's Cryptography: Parallel Computation via Multiple Processors, Vector Processing, and Multi-Cored Chips Eric C. Seidel, advisor Joseph N. Gregg PhD December 30, 2002 Abstract. This paper summarizes my research during my independent study on cryptography in the fal l term of 2002. Here I state the growing need for better cryptography, introduce con-sumer hardware architectures of near future, and identify the growing discrepancy between the hardware on which current cryptographic standard...
  • Frames In The Packets
    2,771 words
    Society has become based solely on the ability to move large amounts of information across vast distances quickly. The natural evolution of computers and this need for ultra-fast communications has caused a global network of interconnected computers to develop. This global network allows a person to send E-mail across the world in mere fractions of a second, and enables even the common person to access information world-wide. With the new advancements in technology there must be a set of "rules"...
  • Pc With A 28 8 Kbps Modem
    2,660 words
    Modems Modems are used to connect two computers over a phone line. Modem is short for Modulator Demodulator. It's a device that converts data from digital computer signals to analog signals that can be sent over a phone line. This is called modulation. The analog signals are then converted back into digital data by the receiving modem. This is called demodulation. A modem is fed digital information, in the form of ones and zeros, from the CPU. The modem then analyzes this information and convert...
  • Token Ring Insertion Process Token Ring Stations
    1,349 words
    Token ring is a local area network protocol which resides at the data link layer (DLL) of the OSI model. It uses a special three-byte frame called a token that travels unidirectional ly around a star-wired logical ring. Token ring frames travel completely around the loop. The name 'Token Ring' is misleading since the physical topology is a loop. Each station passes or repeats the special token frame around the ring to its nearest downstream neighbor. This token-passing process is used to arbitra...
  • Display Map Video
    488 words
    Output devices Bit-mapped displays and Video RAM: Bit-mapped display map video RAM onto the VDU, the number of pixels determines the resolution and the number of bits per pixel determines the dimensions of the color. Typically 8-bits are pretty good. But the colors may be limited to 256 shades per pixel, whereas with a 24-bit output we could have well over 16,000,000 colors per pixel, this however would take up a huge amount of RAM. This is why today's video cards have their own ram buffers as w...
  • Register 5 With The Bit Pattern Ff
    2,235 words
    1. a. A hexadecimal digit can be represented by four binary bits, thus the following hexadecimal notations can be represented as the following bit patterns: i. A 216 -- - 1010 00102; ii. 5 C 16 -- - 0101 11002. b. First, we should determine the bit pattern representation of the following hexadecimal notations as the same way as the above question: i. 8 F 16 -- -1000 11112, Hence, the most significant bit of the hexadecimal notation 8 F is 1. ii. 6 A 16 -- -0110 11002, Hence, the most significant...
