University of Texas at Austin CS310H – Computer Organization and Programming Spring 2008 Don Fussell CS 310H: Computer Organization and Programming (Honors) Lecture 1: Overview Prof. Donald S. Fussell January 14, 2008

University of Texas at Austin CS310H - Computer Organization and Programming Spring 2008 Don Fussell 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
