execution speed using debug

Started by Joe McCarron November 26, 2002
Does using the debugger slow down execution speed of the program?
I've programmed some interrupts to occur periodically (timer int
errupts) and would like to know, when running under the
the debugger, if the periods are accurate.

Thanks
Joe



The debugger doesn't slow down the operation of the processor when you are in the run mode. So the periods under this condition the period should be accurate.
 
If you are doing things like single stepping, hit a break point, use complex software breakpoints, or use the CodeWarrior standard IO features like printing to the console or getting key board entry the operation of the processor is halted to perform this features and hence real time functionality is lost.
