Keywords

Question
How can I determine the size of a real-time application?
Solution
To determine the size of a real-time application, you can use the program x86-size.exe.
x86-size is part of the DS1006 compiler package. It can also be used for PowerPC based boards.
If you do not have the DS1006 compiler available, please download the stand-alone application from
http://www.dspace.com/support_out/_nodel/x86-size/rls62/
x86-size must be executed in a command line box.
Calling syntax:
x86-size <program>.ppc, or
x86-size -A <program>.ppc, or
x86-size -A -x <program>.ppc
Help:
x86-size -h
