Maybe 'top' is actually wrong? Any ideas? What you could do is control one or more GPIO (eg, LED) based on what the code is doing, and measure that with a 'scope. Because the platform GPIO code is slow it can be worth doing it direct to the CPU GPIO register. You'll need interrupts locked out for the duration to remove jitter unless it's the time-to-interrupt you are measuring. That way can learn the absolute duration of these things, the time between them and the rough "density" of the actions. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkj9o9UACgkQOjLpvpq7dMonFACdH31vpM/h/WHtfHoVLjA19aMH qGUAoINUR8V8On4Ts1BmpCc8QW9adakP =ywjT -----END PGP SIGNATURE-----
