Does your embedded risc development platform include profiling? The
best judge of which function need optimization is you, with the help
of your development tools. The profiler should run your code and
measure the amount of time spent in each function, hopefully
providing you with a weighted list so that you can start optimizing
the top candidate right away and then go from there.
