Lab Project #1: Datalab Assigned March 12, 2012; due March 22, 2012 @ 11:59 PM Professor Hugh C. Lauer CS-2011, Machine Organization and Assembly Language (Slides include copyright materials from Computer Systems: A Programmer’s Perspective, by Bryant and O’Hallaron, and from The C Programming Language, by Kernighan and Ritchie) CS-20113, D-Term 2013 Datalab

Introduction – Datalab Objective — to become more familiar with bit-level representations of integer and floating point numbers Approach — solve a series of “programming puzzles” Each forces you to manipulate the bits of an integer or floating point number Limited as to which operations you can use Graded on correctness, performance, and style!
