[Tinyos-users] Profiling code on mica2/mica2dot platform using timer

Wed, 22 Sep 2004 01:19:51 -0700

Hi all,
 
I implemented an FFT algorithm on mica2/mica2dot platform.
 
Now, I want to profile the NeSC code that I wrote. I used two timer to calculate the elapsed time for computing the FFT algorithm and, in particular, I used the SysTimeC component that should provide a timer with 1.2 microsec accuracy (http://mail.millennium.berkeley.edu/pipermail/tinyos/2003-December/000150.html)
 
In your opinion, is it a right procedure to evaluate the performances of mica2/mica2dot motes ?
 
Is there a way to evaluate the processing cycles (Atmel ATmega128L CPU cycles) that my algorithm spends ?
 
Is there a profiling tool for NeSC code or for AVR Assembly (today, I read about AVRORA simulator on the mailing list, but it is a simulator and I want to quantify the real performances of mica2/mica2dot) ?
 
 
Thanks in advance,
 
Alessio
 
 
P.S: I attach a piece of my code ...
