Debugger takes code profiling onboard
Tools from American Arium now support optimisation via code profiling
With SourcePoint 6.1, Arium's hardware-assisted flagship debugger for ARM and Intel XScale processors, developers can determine which functions are called most often and take the longest time to execute. Results helps them fine tune their code to get it running faster and more efficiently. "SourcePoint code profiling helps users whose code goes off into the weeds", said Todd Selbo, Product Marketing Manager, Arium Sales and Marketing.

"It highlights the slow pieces of code and makes the data available in a user-friendly format".
"It helps developers determine where they can squeeze their code to make it run faster".
Specifically, code profiling measures the amount of time a processor spends in an address range based on periodic sampling of functions.

Unlike Arium's performance analysis feature, code profiling does not require an ARM processor with an embedded trace macrocell (ETM).
Specific advantages to using SourcePoint code profiling include: setup is easy and intuitive; it is not limited to specific compilers, and there is no need to recompile code; it does not alter the code or the timing of the experiment; and it yields accurate results, helping to improve users' time to market.
Arium has developed a GUI that makes it easy for users to set up an experiment and provides clear and accurate results.
In the "code profiling" window, users may choose to profile all functions or select specific functions and profile just those.
During profiling, the "code profiling" window displays the number of times each function is encountered along with a percentage relative to the total of all functions.
The window updates in real time as the program runs.
All results can easily be saved to a file for further analysis.
SourcePoint 6.1 is available from Logic Technology.
