[Mep-dev] Adding NEON Support to FFTW

[Michelle]

According to Bob McGwier, Philip Balister, and several others, a very useful next step in being able to fully use the TI OMAP processor for MEP as well as other projects is to add NEON support to packages such as FFTW (fastest fourier transform in the west).

Several helpful links:

Broadly defining NEON   http://www.arm.com/products/multimedia/neon/index.html
FFTW   http://www.fftw.org/

Phil Balister recommends that in order to start with FFTW, one should untar the source on the
beagle board (the beagle board processor has an ARM with NEON) , then build an SD card with task-native-sdk, and then compile FFTW. A directory in the FFTW called simd is the first place to try adding NEON code.

The next step is to define what exactly we mean by "adding NEON support to FFTW" in order to understand the scope of the problem, then divide up the work, and make some forward progress.

Who has a beagleboard and/or wants to participate? I have beagleboards that I will loan for this project, in exchange for participation.
