How to measure number of cycles of a C code

[Tiza Naziri]

Hi, I have written a C code of an encryption algorithm. How do I measure the number of cycles of my implementation? Hope to get some feedbacks/suggestion from the forum members, or can email the feedbacks to my email address watija@yahoo.com. Regards, Tiza Naziri, Malaysia

just put a Counter(an unsigned int or long or anthing like that) in your Cycling Function( :-D ) i.e. encryption algorithm. and every time the Encryption Algorithm make a cycle, increment the Counter by one, and when your cycling function end, you will get number of cycles in the Counter

if you want to count the CPU cycles, you must set up a highperformance timer. check out the articles on timers here on CP. http://www.codeproject.com/datetime/ccputicker.asp[^]

if you want to know CPU cycles (ex. "it takes X cycles to do one round"), you'll have to analyze a machine-language implementation of your algorithm. Image Toolkits | Image Processing | Cleek
