Summer code of ideas for 2009
NEON Support for FFTW
FFTW is a library for calculating the Fast Fourier Transform. The current implementation of FFTW contains SIMD optimizations for several instructions sets. It should be possible to add optimizations for the NEON SIMD co-processor in the Beagle Board. FFTW is widely used in the open source sommunity and this project would make FFTW far more useful on processors with NEON instructions. The mentor is particularly interested in improving GNU Radio on the OMAP3 and improving FFTW performance would be very useful.
Codec Engine (C64x+) implementation of Ogg Theora
There was a Neuros GSoC project to port Ogg Theora to the C64x+ last year, but it was never finished. See the Neuros project page to understand the status.
Voice recognition integrated into Ubiquity
Integrate Mozilla Firefox, Mozilla Ubiquity, and voice recognition on the BeagleBoard with a microphone. Use of a Wiimote could provide additional interactive capabilities.
Spectrum analyzer using the DSP
Write a program that uses the DSP to take an alsa input and to all the math and a GUI on the arm that display the realtime spectrum. The DSP side needs to use xdais so other DSP programs can run at the same time.
ideas not worked out
- more codecs on the dsp (e.g. mp3 encoder/decoder, mpeg2 decoder, codecs for IP telephony (with video), ...)
- port LXDE (see www.lxde.org)
- beagle as upnp renderer
- beagle variant of "from 0 to 60 in 5 seconds" make a beagle that starts in < 5 seconds
- good text to speech support
