Summer code of ideas for 2009
Student proposals can create projects from the following ideas, or students are free to propose their own project based on their own ideas. 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 help students develop ideas into projects on irc or the mailing list.
MP3 player based on Beagle Board. This could involve porting Rockbox (www.rockbox.org) - an open source firmware for mp3 players to Beagle Board. Additional effort would involve creating Rockbox plugins to port the audio decoders and encoders to the DSP side. MTP device class support need to be added on USB as well.
Video Chat Client on Beagle Board. Porting Ekiga (www.ekiga.org) - an open source VoIP and video conferencing application for GNOME. The client should be able to talk to ekiga software running on PC as well as another beagle board. Optimizations would involve porting audio and video codecs on Ekiga to DSP plus supporting video streaming over USB for webcam support.
Ubuntu Mobile on Beagle MID
Porting ubuntu mobile version on Beagle board (http://elinux.org/BeagleBoardUbuntu) and enable support for standard applications used in standard internet tablets/MIDs - media player, browser.
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 acceleration
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
Power consumption is a major problem in mobile devices. While there are many HW level power management features in processors such as the OMAP35x, SW lacks the ability to manipulate and control those features. Research those power features and implement kernel APIs to allow applications to manage their power more efficiently.
OpenGL DSP acceleration
Research and implement OpenGL ES using the DSP on beagleboard. The DSP side needs to use xdais so other DSP programs can run at the same time.
Adding Sense to Beagle
Sensory aware applications are becoming more mainstream with the release of the Apple iPhone. This project would combine both HW and SW to add sensory awareness to beagle. First, additional modules such as GPS, 3-axis accelerometers, Gyroscopes, Temperature Sensors, Humidity Sensors, Pressure Sensors, etc, would be added to beagle to compliment the microphone input in order to allow sensing of the real world environment. Then SW APIs would need to be layered on top to allow easy access to the sensory data for use by applications.
Port XBMC Media Center to Beagle Board
XBMC is an open-source, cross platform media center that would allow you to display high definition video on your TV that is streamed from your local network or the internet. XBMC on Beagle Board would would be a very low cost, low power platform that would allow the media center to literally be embedded in the TV. XBMC could run on an Ubuntu distribution of Linux and would requiring the development of OpenGL ES complaint DirectFBGL drivers.
Smart Energy Monitoring Console
The ZigBee Smart Energy profile is a wireless standard for utility companies and consumers to securely monitor and manage home energy consumption by communicating directly with smart appliances that report their power usage. By interfacing the Beagle Board to an MCU and RF transceiver monitoring the energy consumption of a home and it's appliances, the Beagle Board could act as a dedicated terminal to track and control energy usage of power hungry devices.
Wiigle Board (low cost video game platform)
Develop an open source platform for video game development by generating the drivers to standard interfaces such as wireless accelerometers or game controllers. Off the self microcontrollers can be leverages to handle the I/O and RF interfaces, and the Beagle Board would handle all processing and display. By generating a clean, open standard, the community could port existing games or use this as their preferred platform for video game development. The concept could be extended by porting known console emulators (NES, Genesis, SNES, etc) to run classic games on a unified, low cost platform.
Development or tuning the an emulator like qemu to emulate the x86 instruction set at a reasonable speed to run legacy x86 apps developed for another non Linux OS. Possiblities include Windows 9x, 2000, etc. An alternative approach to use qemu to emulate an x86 Linux system and run Wine up top of that. Yet another approach might be to add an emulation engine inside wine. The goals is to be able to run x86 applications. The OS is optional.
The MUSB block on the Beagle has a lot of potential but the driver is currently rather buggy. This project will be to fix the driver so the MUSB implementation as paired with the PHY used on the Beagle board can work reliably as a USB OTG device. This means it should be able to at least reliably go back and forth between host and device mode without a reboot by just changing from a A to a B cable AND be able to force host or device mode in software. See the Nokia N8x0 devices for a sample behavior of how software can force this. An initial estimate is code needs to be implemented to force the PHY into host or device mode as requested by SysFS.
