Hello I am using C51 Compiler for AT89C51. How can I Count clock cycle consumption for a Piece of C Code e.g P1=(int)(((sin((2*PI)*(((double) (k++))/MAX))+1)/2)*BYTE); ????????? How many clks it will take ??? ????????
Keil has a web page where you can get the minimum, average, and maximum times for the floating point function calls. You could add those up to get an idea of how long calculating that expression would take. http://www.keil.com/benchmks/tm_c51_v7_small.asp
"Keil has a web page where you can get the minimum, average, and maximum times..." and if you look at that page, you will see that there can be a 2:1 (or more!) ratio between the minimum and maximum! Like I said earlier: there is not a single, constant answer to this question!
