  1. CS 310: Computer Organization and Programming Lecture 1: Overview Prof. Donald S. Fussell January 14, 2008 University of Texas at Austin CS310 – Computer Organization and Programming Spring 2008 Don Fussell

  2. Goals • Understand the fundamental components of computer systems • Hardware • Machine language • Assemblers • Compilers • Operating Systems • Learn to program the machine at its most basic level • Why? Can’t we just use a high level language? • SW design decisions are driven by the HW • Understand program performance • It’s pretty darn cool! • Without this knowledge, it’s kind of like being an architect without knowing anything about construction University of Texas at Austin CS310 - Computer Organization and Programming Spring 2008 Don Fussell
