[PATCH] Adjust handle_hpet_broadcast to let it run better before broadcast exit
Adjust handle_hpet_broadcast to let it run better before broadcast exit
Since hpet_broadcast_exit has been moved after interrupt enabled in C3
case, so adjust the handler of hpet broadcast to adapt to this.
Meanwhile, remove a freqently executed debug print line to simplify the
serial output.

What goes to Hardware ?
Hi people,
As I said before: I did the IDCT to run on the FPGA.
My friends from university did the Reconstruction routines running on the FPGA.
I'm helping with the LoopFilter, and it is almost there.
(all VHDL)
I did a small profiling of the libTheora running on a Altera Stratix II device:
The processor used was the NIOS II with 8Kb of data and instruction
cache, branch prediction and

Next step of Hardware Theora
Hello,
First of all, I would like to say that my work that I wrote in the other
email would be to do in hardware the functions: CopyRecon, LoopFilter and
UpdateUMVBorder. These are modules that Leonardo had made, but it wasn't ok
in FPGA. When I had a chat with Leonardo we were thinking in rewrite these
module for to do this running in FPGA (to debug in a Hardware level is much

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

dead DCSearchPoints code
Dan,
In reviewing the code, derf came across the DCSearchPoints array in
QuadCodeDisplayFragments(), encode.c:696. It looks like it specifies a
search order for nearby coded fragments for prediction if there isn't a
nearest neighbor. However, the upper search bound is defined as *0*, so
the search loop (line 917) is never executed and it always falls back
to the last coded fragment.

More Missing Pieces
Hi,
I am making good progress on understanding, documenting, and
re-implementing VP3. I have found some more deadwood in the decoder code
and I just wanted to verify that it really has no place:
* Version 3.3 tables: There are 2 sets of VLCs: One for v3.1 and one for
v3.3. The v3.1 set is always selected. Are the v3.3 tables in production,
or will they ever be?
* DC Search Points: VP3

Theora mcomp tuning...
Hi there.
This patch changes the block selection to quantify error
based on the sum of the squared differences of the pixel
values rather than the sum of the absolute differences,
the former conventionally and statistically seeming like
the preferable thing to do.
The patch also const'ifies some parameters (which doesn't
affect code quality on recent GCCs but might help on older/
other

Patch that fixes distortions during static scenes
Here is a patch that fixes distortions that appear during scenes with no
motion. Tbe problem was that UpdateFrame() was not being called when a
MotionScore of 0 was computed. Since UpdateFrame() was not called the buffer
returned by theora_encode_packetout() would be the same buffer that was output
for the last frame that had a non-zero MotionScore. This is obviously incorrect
behavior. I've

[theora in hardware] Contents of YUV_BUFFER_ENTRY
Hi everyone, it's my first e-mail to this list (my classmates from college
have sent a few though), so i'ld like first to greet everyone and
congratulate all the people responsible for all the work with this theora
project.
So, to my question:
As you probably know, we are working on an implementation of the theora
codec on hardware. I'm currently responsible for getting the function
