speex/README.blackfin

Speex has been ported to the Blackfin DSP, for the STAMP development board.

This port has been tested on the STAMP development board and requires the 
toolchain available at http://blackfin.uclinux.org/

1/ In order to cross-compile for uClinux from the Speex tarball:

  ./configure --enable-blackfin-asm --enable-fixed-point --host=bfin-uclinux
  cd libspeex
  make

The --enable-blackfin-asm option is not required, but it speeds up Speex by
approximately a factor of two.

2/ In order to cross-compile for uClinux from the Speex Git:

  git clone git://git.xiph.org/speex.git
  cd speex
  ./autogen.sh --enable-blackfin-asm --enable-fixed-point --host=bfin-uclinux
  cd libspeex
  make
