AddLoop 0.03a   (details) 48 ENG   6 KB / 1 KB
This is a collection of three monolithic code objects written in Saturn assembly that perform the calculator "add loop" benchmark ( eg. x = + 1 ). One code object has no loop unrolling and the other two have progressively higher levels of loop unrolling. Note that this code will only run on a G/G+/GX-R which does not have a merged port 1 RAM card.
