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
