DSK6713 profiling using clock counts

by John Smith <John@[EMAIL PROTECTED] > Jun 27, 2008 at 10:36 PM

I'm using DSK6713, and I'm profiling a C program, in Debug mode & -o3 
optimization build.  The clock counter for  operation such as 
par->bpvc[1]=1.0; is 6, even though the C code is compiled to the 
following single ASM operation:
[A1]    STW.D1T1    A12, *+A10[23]

How do I have to treat the clock counts?  Since the DSK6713's clock is 
225MHz, do I have to compute for the above operation a computation 
real-time of 6/225,000,000 second ?

The clock counts that I receive are outrageously high, what's going on
here?

Thanks,
JS
