Summer code of ideas for 2009
Student proposals should expand on these projects, or students are free to propose their own project. From reading about previous Summer of Code, the key to success are people passionate about their project, so propose something that is extremely interesting to you, even if it not on the list. We will be glad to talk about your ideas on irc or the mailing list.
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.
Utilizing voice recognition on the BeagleBoard with a microphone, submit text to Google Translator, then perform text-to-speech.
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.
Come up with a USB sniffer solution. Idea is that the device to be sniffed is connected to the USB host port of the beagle and the beagle itself to the original host. The beagle will pass-trhu all usb data while logging that data. This could be a great help diagnosing USB problems or reengineering USB communication to a device (by logging the behaviour of a device when connected to a PC (software solutions for that exist too (usbsnoop), but a hardware solution could also support replay etc.
USB device audio support
The Linux USB gadget infrastructure doesn't have audio device class support (but Linux does have USB host audio support. There is some work on a gadget MIDI audio driver. Some work has been done over at Blackfin, but is reported as not working very well. Getting USB isochronous endpoint, gadget audio driver connected to audio on BeagleBoard would be beneficial to all OMAP3 isochronous USB needs, better isochronous gadget support in Linux (there are no standard gadgets test for isochronous endpoints), and a prove out a real gadget driver that requires isochronous endpoints. Anyone wanting to learn about communication protocols, a well designed layered communication implementation, and a chance to work at the driver level will enjoy this project.
Touchscreen and LCD open hardware design
BeagleBoard rev C has a new connector for attaching an LCD. The Touchscreen and LCD open hardware design project would consist of a schematic, PCB layout, and bill of materials that can be purchased easily over the Internet. On online PCB fab could make the PCBs cheaply. Only a soldering iron should be needed to populate the PCB. Once built, the user could connect the PCB to their BeagleBoard had have an LCD with touchscreen support. This project is targeted toward those interested in hardware and shouldn't require any complex software if a well supported touch screen controller chip is selected.
OpenCV DSP accelleration
Research and implement hardware acceleration for OpenCV using the DSP on beagleboard. The DSP side needs to use xdais so other DSP programs can run at the same time.
Power Aware Computing APIs
The OMAP35x devices have a wide array of power management features. Research those power features and add kernel APIs to allow applications to manage their power more efficiently.

- 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
- Clean MythTV, Boxee, XBMC, or Miro builds
- facial recognition with depth analysis using pico projector and webcam
- high-speed 3d scanning with pico projector and webcam
- USB class converters (MTP to mass-storage, audio to midi, ...) or invasive sniffer
