Hi all,
I just completed my first 512K FFT using the new SSE2 instructions!
The 512K FFT handles exponents up to 10.3 million.
Timings are as follows:
1.4GHz P4, old code: 0.126 sec.
1.4GHz P4, new code: 0.048 sec.
1.2GHz Athlon, 133MHz DDR: 0.084 sec.
I have a few more optimizations up my sleeve. I think my goal
of 0.040 seconds is achievable.
Having fun,
George
