Hello to the Keil Software Discussion Forum: My name is Randy Norris and I am with NORgate Engineering & Associates. We are considering using the 8051 for an online signal processing application and our question is this: Does the Keil 8051 C compiler have the capability to use arithmetic functions such as sin, cos, log, sqrt, etc? Our guess is that the answer is yes, and a statement at the beginning of the code like #include <math.h> would be required. However,this is only an educated guess. We have an evaluation version of Keil software from 2 years ago, and the User's Guide 11.97, but this documentation does not address our question. Thanks for your help. Randy Norris
It will do them but another question would be how fast you need them done. This will give you some idea of the speed of the various function depending on which memory model you are using. But do remember that you can get 100MHz one clockers (SILabs F12x) = 100 times faster than the "traditional" '51 Erik
