ARM / NEON

Len Koss

Other Parts Discussed in Thread: OMAP3530

Hello,

I'm currently using the OMAP3530 and I'd like to benchmark an FFT on the ARM while making use of the NEON intrinsics so I can compare with the performance obtained when running a TI optimized library FFT on the C64x+ core.  So i have the following questions:

1) Where can I find FFT code that's been optimized to run on the ARM / NEON?

2) Where can I find some benchmarks for FFTs running on the ARM / NEON?

Thanks,

Len

    Hello Len,

    1. Open source FFmpeg libav codecs have been optimized to use NEON intrinsics. Mans Rullgard's personal repository with works in progress is at git://git.mansr.com/libav.git. FFmpeg v0.6.1 is the latest stable release.

    2. This is still work in progress, please refer to his thread in the forum for some additional information: http://e2e.ti.com/support/dsp/omap_applications_processors/f/447/p/71122/259776.aspx
