  • 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...
  • Data Path Control Fsm
    419 words
    Engineering Plans 312 Final Project 11/7/04 Names We plan to implement the basic multi-cycle processor design as shown in the textbook, as well as pipe lining and "jump and link". The toughest part of this design will be the data path control, for which we will be using a FSM. The ALU will implement add, sub, and, or, sell, and set functions - though a separate block is typically used for shift operations, we felt that putting sell and sr l in the ALU would simplify our design. All other basic f...
  • Machine Instructions In Different Memory Locations
    3,711 words
    Computer Architecture 1. There have been a lot of developments in microprocessors since the 286 chip. The 286 CPU are no longer sold and are very rarely found in commercial use today because of its running speed, which is between 10 MHz to 20 MHz. This processor has a 24-bit address bus, and is able to address up to 16 million different address locations. It also has two operating modes, which are real mode and protected mode. The real mode is basically for normal DOS operations and it uses only...
  • New Data Types And Instructions
    797 words
    MMX TM Technology The MMX TM Technology extension to the Intel Architecture is designed to accelerate multimedia and communications software running on Intel Architecture processors (Peleg and Weiser). The technology introduces new data types and instructions that implement a SIMD architecture model and is defined in a way that maintains full compatibility with all existing Intel Architecture processors, operating systems, and applications. MMX technology on average delivers 1.5 to 2 times perfo...
