Course Computer Systems

"Computersystemen"

Week 36, September 7-8 2011

Description

A computer system encodes information of bits, organized as sequences of bytes. Different encodings can be used to representing basic data concepts as integers, real numbers and character strings. Understanding of these encodings at the bit level, as well as understanding the mathematical characteristics of the arithmetic operations, is important for writing programs that operate correctly over the full range of numeric values.

In this class the following concepts are introduced:

  • hexadecimal notation, bit-level operations, logical operations, shift operations
  • integer representation and aritmetic
  • floating point representation and aritmetic

Literature

The class is based on chapter 2 of the book Computer Systems: A programmer's perspective by R.E. Bryant and D.R. O'Hallaron.

Recommanded reading (85 pages, 4 hours):

Chapter 2    Representing and Manipulating Information
