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.
