theora dev - May 2007 - Theora running on FPGA

Great news! Theora is running on FPGA.

After almost a year of a great effort we have Theora validated on
FPGA. Now I will try to integrated the hardware with a video
controller to see the video!

I completely implemented the ExpandBlock, CopyRecon, LoopFilter and
UpdateUMVBorder functions.

The ReconRefFrames function was partially implemented and the part
before will run on a software compiled for Altera Nios2 Processor.

The implementation is based on version alpha6 and due FPGA SRAM memory
constraints the maximum resolution is about 280x210. Increase the
resolution, will require a SDRAM controller. The hardware has a module
to manage the access to the buffer then I think that wouldn't be
difficult to do this change, but for the moment I won't do that.

Others future project could be a completely hardware implementation or
the integration with a  nonproprietary processor.

I will comment the code better and post in the SVN the quickest as
possible. I will did a little movie with the video playing when I
finish the integration with the VGA controller.

I want thanks Felipe Portavales Goldstein to the support and help.

This great news! Thanks for continuing to work on the project.

Andre Luiz Nazareth da Costa will be picking up this work for this 
year's Google summer of code. Please do an interm check in of what 
you've got now to give him as much time as possible to review it; 
you can commit the clean up later.

Looking forward to to video,
 -r

This is great news!

You did a really amazing work! This is something to celebrate!
And now there is Andre working on the project too, this is really good.

I am proud to see the small project that I started is becoming a great project!
The work that Leonardo did is much bigger and complicated than the
work that I started with my Summer Of Code last year.
He did great!

Congratulations!

Cheers,
Felipe
