In view of all the real difficulties highlighted by many, why not try
this approach:
A simple command like dd if=/dev/zero of=/dev/null bs=4 count=100
_timed_ would take a finite period on your embedded system. If cpu load
went up, time taken would go up. Set the process priority as low, and
graph your machine's performance under increasing load.
Then scale it in percentages. If you want to be really fancy, factor in
number of processes ( perhaps ps -e | grep -ce '\n'), lack of memory
(free), or other such data and you'd have a tailor made app.
