[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. Signed-off-by: Wei Gang <gang.wei@intel.com> diff -r 63317b6c3eab xen/arch/x86/hpet.c ---

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 more

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
