Alogrithm Performance

Note: This was originally posted on 31st July 2009 at http://forums.arm.com

Hello,

I am developing algorithm using ARM NEON instruction on for OMAP3530 (BeagleBoard).
I am using Angstrom root file system and it's binaries to run algorithm on OMAP.
I am building application using Code Sourcery G++ 4.3-205 toolchain.

Does it have any performance issue of application which built with codesourcery and run on Angstrom root file system ?

Thanks,
rach

My only thoughts would be that not many C compilers are great at vectorizing code, so don't be surprised if you have to dive in to assembler if you want some specific code running fast.

Hi,
I am using ARM - NEON assembly Instructions in my routine not c code.
Does it have any effect of performance in application if my application, binaries and root file system compiled with different tool chain?

Thanks,
rach
