COMPARISONS - COMPILER OPTIMIZATION

FFT Order	Level 1 Optimization	Level 3 Optimization
16 64 256 1024 4096 16384	10 40 160 760 3940 18180	0 40 140 660 3720 17420

Computation Speed (us) vs. Optimization Level

Split-Radix algorithm used for comparison

Level 1 does code size and execution time reduction

Level 3 optimizes without space-speed tradeoff
