Description should be no longer than a paragraphFedora-ARM does not use thumb. Include links The purpose of this project is to discover whether thumb provides any relevant significant savings in terms of code size, whether programs compiled to thumb execute more quickly or more slowly than non-thumb programs oncommon ARM processors, whether a thumb compilation takes more or less time than non-line resourcesthumb, and whether there are any other factors that would influence the decision to support thumb. For exampleUltimately, http://google.com or [http://developer.mozilla.org MDC]this project should make a recommendation on the use of the thumb instruction set for the Fedora-ARM secondary architecture.  

I will be working alone for this project.  My name is Tae Hee (Tyler) Leeand I'm taking SBR600 course in 2010 Winter Semester. Blog @ http://tyler-taehee-lee.blogspot.com/search/label/SBR600

NOTE: only Project Leader(s) should add names here. == What I need to learn ==  - rpmbuild - /usr/lib/rpm/redhat/rpmrc - /usr/lib/rpm/redhat/macros - time - screen - yumdownloader You '''can’t''' add your own name to the Contributor list.- rpm2cpio

* 0.1Determine whether THUMB gives advantage in file size compared to NON-THUMB.* 0.2Compare and contrast file sizes between NON-THUMB, THUMB and THUMB2.* 0.3Compare the performance of software compiled with THUMB and NON-THUMB   == Collaboration with classmates == I collaborated with [http://zenit.senecac.on.ca/wiki/index.php/User:Mjeamiguel Mark Eamiguel]. We made arrangements so that I used ''cdot-beagleXM-0-3'' during the day time, and he used during the night to avoid interruption on our benchmarks. There was one night our works on that machine became useless since both of us were compiling at the same time which caused performance drop. We also gave each other tips on working with these remote systems, such as using application ''screen'' and command ''who''.   == Test results == '''Following are the table of file sizes that are produced by ''rpmbuild'' in bytes.''' <br /><div><b>nled-2.52</b></div><div>Produced RPM: '''nled-2.52-6.fc12.armv5tel.rpm'''</div><div>Directories and files: 2 directories, 1 file</div><div>Binary

about,<div>'''2.24%''' for *.rpm files,</div><div>'''7.67%''' for extracted directories, and</div><div>'''22.16%''' for executables, compared to NON-THUMB.</div><div>While it might save some disk space for executable files, it doesn't make a big different for rpm packages since rpm has it's own compressing mechanism.</div> Compared to THUMB2, In average, THUMB produced files that are about,<div>'''0.24%''' for *.rpm files,</div><div>'''0.45%''' for extracted directories, and</div><div>'''1.86%''' for executables, greater than THUMB2.</div><div>I noticed that THUMB produces files that are almost as small as THUMB2's products.</div> Just based on file size comparison, THUMB does an excellent job shrinking the file size. Performance benchmarks showed too much fluctuation in the result to provide a firm answer. At this point, my conclusion is that THUMB does not greatly effect in software's performance, but it varies depending on software. So far I've seen more improvements than decrements from THUMB. As I'm aware of that more benchmarks are required before having an concrete answer, but for now it is safe to say that THUMB for Fedora-ARM is worth further development.  

This is where your regular updates will goOctober 8th, 2010 - Project started October 14th, 2010 - Major project page update with more information. In these you should discuss the status  November 5th, 2010 - To Thumb? or your workNot to Thumb? (v0.1) November 12th, your interactions 2010 - Noticed v0.1 was incorrect. Tried a different approach compiling with other members of make file. November 15th, 2010 - Figured out '''%optflags''' is located in /usr/lib/rpm/redhat/rpmrc November 20th, 2010 - Figured out that I was comparing the community (ewrong *.rpm files.gStarted all over again. November 27th, Seneca 2010 - Correct file size comparison and Mozilla)performance benchmarks updated. December 7th, problems you have encountered2010 - Presentation regarding v0.3 to Chris Tyler and SBR600 class. December 14th, etc2010 - Project (v0.3) completed.   == Resources == ARM Architecture - http://en.wikipedia.org/wiki/ARM_architecture#Thumb
