Thus, the time spent on the return is actually time spent in the
epilog of the function. You options are to reduce the number of
calls to the function or to inline it.
- The function runs very quickly but is also called frequently. In
this case, Nyquist might require a faster sampling rate. The
default is 1ms, but 100us is still reasonable. If the profile
changes when using 100us, you were seeing aliasing.
Or maybe if the function is approximately synchronized to the
sampling timer?
