Project Name

To Thumb? or Not to Thumb?

Project Description

Fedora-ARM does not use thumb. The purpose of this project is to discover whether thumb provides any significant savings in terms of code size, whether programs compiled to thumb execute more quickly or more slowly than non-thumb programs on common ARM processors, whether a thumb compilation takes more or less time than non-thumb, and whether there are any other factors that would influence the decision to support thumb. Ultimately, this project should make a recommendation on the use of the thumb instruction set for the Fedora-ARM secondary architecture.

Project Leader(s)

I will be working alone for this project.

My name is Tae Hee (Tyler) Lee and I'm taking SBR600 course in 2010 Winter Semester.

What I need to learn

- rpmbuild
- /usr/lib/rpm/redhat/rpmrc
- /usr/lib/rpm/redhat/macros
- time
- screen
- yumdownloader
- rpm2cpio

Project Plan

Goals for each release:

  • 0.1 Determine whether THUMB gives advantage in file size compared to NON-THUMB.
  • 0.2 Compare and contrast file sizes between NON-THUMB, THUMB and THUMB2.
  • 0.3 Compare the performance of software compiled with THUMB and NON-THUMB
