https://devzone.nordicsemi.com/f/nordic-q-a/5995/how-to-calculate-instruction-cyclesI have an algorithm which does quite a bit of number crunching. I&#39;d like to know how many clock or instruction cycles this algorithm is using. How can I get or calculate the instruction cycles?en-USTelligent Community 13Wed, 11 Mar 2015 21:25:02 GMThttps://devzone.nordicsemi.com/thread/20921?ContentTypeID=1Wed, 11 Mar 2015 21:25:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:868799df-cf14-4fa8-9f02-870ae6ca68e2Charles Manning<p>With some tools and simulators it is possible to determine this theoretically.</p> <p>What might be better though is to just toggle a GPIO when you go into the code, then again when you come out, and use a scope to measure the execution time.</p><div style="clear:both;"></div>
