  1. INEL 4215: Computer Architecture and OrganizationInstructor: Nayda SantiagoSpring 2004 Lecture 2 Department of Electrical and Computer Engineering University of Puerto Rico - Mayaguez

  2. Important - Abstraction • Designers must know both SOFTWARE and HARDWARE • To contribute to both layers of abstraction of computers • To improve performance • To design compilers and operating systems

  3. Chapter 1: The General Purpose Machine Topics 1.1 The General Purpose Machine 1.2 The User’s View 1.3 The Machine/Assembly Language Programmer’s View 1.4 The Computer Architect’s View 1.5 The Computer System Logic Designer’s View 1.6 Historical Perspective 1.7 Trends and Research 1.8 Approach of the Text

  4. Chapter 1 – A Perspective • Alan Turing showed that an abstract computer, a Turing machine, can compute any function that is computable by any means • A general purpose computer with enough memory is equivalent to a Turing machine • Over 50 years, computers have evolved • From memory size of 1 kiloworld (1024) clock periods of 1 millisecond (0.001s) • To memory size of a terabyte (240) bytes and clock periods of 1 ns (10-9 s) • More speed and capacity is needed for many applications, such as real-time 3D animation
