Getting Started With Blackfin Processors

PocketSphinx

A version of the open source Sphinx-II speech recognition system
which runs on handheld and embedded devices. This snapshot is now
running under real time on the Blackfin/µClinux.

Adeos and Xenomai

Adeos provides a flexible environment for sharing hardware resources
among multiple operating systems, or among multiple instances of a
single OS. Xenomai is a real-time development framework cooperating
with the Linux kernel. It provides real-time support to user-space
applications, seamlessly integrated into the GNU/Linux environment.
Xenomai is based on Adeos.

kaffe

A clean room implementation of the Java virtual machine, plus the
associated class libraries needed to provide a Java run-time environ-
ment.

xmame/xmess

Ports of MAME, the multiple arcade machine emulator and MESS,
the multi-emulator super system.

BlueZ

An implementation of the Bluetooth™ wireless standards specifica-
tions for Linux. The code is licensed under the GNU general public
license (GPL) and is now included in the Linux 2.4 and Linux 2.6 ker-
nel series.

FFmpeg & vlc

FFmpeg is a very fast video and audio converter. It can also grab from
a live audio/video source. On the Blackfin processor, we couple it with
vlc (video LAN client) to make a free IP camera.
