Code Size and Speed

Note: This was originally posted on 14th June 2013 at http://forums.arm.com

I have inherated some ARM Code that I need to tidy up.

Keil uVision4 RealView compiler.

This Code is full of Variables of type "short" non of them need to be signed.

Would it reduce size and increase speed if i converted everything to "unsigned short" ??

From my 8051 days I would say def yes.

Yes (Thumb only impacts the size of the instruction words, not the size of the data registers).
