About this topic about increasing DSP speed with FFTW optimization:

three things are bothering me at the moment:

a) topic is for http://gitorious.org/gsoc2010-fftw-neon source, but
there is a newer
Should I build this newest the same way?

b) as far as i understand, the topic describes compiling source on PC
and then installing it on Beagleboard. How do I compile it on

will this work if I'm configuring on BB, not on PC?
CFLAGS="-O3 -pipe -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp" \
./configure --prefix=/usr --enable-single \
--enable-shared --with-pic --host=arm-none-linux-gnueabi \
--enable-armv7-cycle-counter --enable-neon

I don't really understand what these mean and why they are needed: -O3
-pipe, --enable-single --enable-shared --with-pic, --host=arm-none-
linux-gnueabi. I think the last one isn't needed when compiling on BB?

c) topic says I should install Mans Rullgard's USER_PMON patch
http://git.mansr.com/?p=linux-omap;a=commitdiff;h=5170038 if I'm using
--enable-armv7a-cycle-counter. How do I install this patch?

Please help?
