Måling af eksekveringstider



Hej,

Jeg er interesseret i at kunne måle eksekveringstider for enkelte
funktioner i et program, for at kunne optimere den samlede
eksekveringstid (CPU-time).
Umiddelbart skulle man synes at dette er en opgave for 'gprof', men
opløsningen er slet ikke fin nok. (De enkelte funktioners
eksekveringstid er <1us.) 
Desuden er målet i sidste ende at kunne lave er run-time optimering at
hvilke funktionelt kompatible funktioner der anvendes.

Så det jeg egentligt ønsker er en form for metode til måling af antallet
af clock-cycler der anvendes til afvikling af en funktion.

Ka' man det? Og ikke mindst hvordan!

Med venlig hilsen
Egon Andersen
