Next step of Hardware Theora
...cult, sometime is faster rewrite the code). But, Leonardo
discovered the mistakes on ExpandBlock and in the integration of modules in
FPGA. The result is that all these modules are running in FPGA and don't
need to be rewrite.
Current State of Theora Hardware

Well, now I need to change the line of my project on GSoC. I wrote some of
tasks that are necessary to have a Hardward implementation of Theora.
1 - Integration with a processor (Nios vs Leon)

We will need to compil...

Theora hardware is running on LEON3!
...oints on software (the hardware is the same,
LEON+Theora_hardware):
[a] Theora on LINUX: we have a .ogg file that can be decoded on FPGA and
shown on a monitor. But it can't be decoded in time of exibition. I suppose
that the problem is the LINUX system call.

[b] Theora without LINUX: Here, we can to decode much faster that the time
of exibition. But, without LINUX, we can't to use a .ogg file directly, we
need to convert it in a vector and to compile with dump_video (the Leonardo
also needs to do it on NIOS)...
