similar to: Theora Decoding on FPGA

Good news, Working with synchrounous RAM (fpga internal SRAM blocks) the area usage drop from 20% to 5% of Logic Cells. And the clock frequency from 30 Mhz to 90 Mhz. Now I'm improving the latency of samples (number of clock cycles needed to decode a data sample).

Hi all, Just a stupid question The IDctSlow function on file idct.c has this line : ip[0] = (ogg_int16_t)((_Gd + _Cd ) >> 0); The ip[0] , _Gd and _Cd are of type ogg_int32_t My question is: The result of (_Gd + _Cd) can be a number with more than 16 bits ? (yes, it can be because they are int32, but the algorithm could guarantee something about that... I dont know...) If

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

Hi, I am sending my application I submitted for the GSoC. There are still some hours left before the deadline, so if you have any remarks or a tip, I can still update it. thanks... i think there are some grammatical errors =(... == Name and Contact details == Andr?

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

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

Hi, I just installed a fresh CentOS 6.6 desktop. It's a client's machine, it is physically installed on a testbench in my office. Usually, when I perform installations, I start with the base system on the testbench, and once networking is configured, I SSH into it and then do all the fine-tuning remotely. My configuration files, scripts and HOWTOs are all stored in a Github

Great! Can you please check in that test case or better still, a reduced version of that test.

Shows that as the MCU increases, the OpenMP extra overhead is amortized and OpenMP becomes as fast as the pthreads implementation. The last chart http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/systime.png Shows that both pthreads and OpenMP overhead decreases as what seems to be a logarithmic function of the MCU size. This was a great experiment, and from what I can conclude, the OpenMP

Hello, I'm happy to announce I developed a Multi-Threaded version of the Theora encoder. I changed the Motion Vector Search part of the algorithm to be executed in parallel. I've chosen the Motion search part after a careful set of profilings that shown that the Motion Vector Search is responsible by 70% of CPU-time on average and up to 95% of CPU-time in some cases. I also have chosen

Hi Anshu, the "test case" I referred to requires the compilation of our whole back-end. It segdaults when using gcc-4.4.3 under Ubuntu 10.04, with other combinations I have tested it still happens (before your patch) but is not noticeable unless using gdb. I have tried making valgrind catch it but no success... so I guess the only way to *see* it is using the debugger. I remember

Hi again, I can confirm r169783 fixes the problem. My testbench segfaulted in r169782 but works after your commit. We can close the issue.

Hi, I did some improvements and some bug corrections in Theora FPGA code. I'd like to post this new version in the SVN. How can I do that? Thanks -- Leonardo de Paula Rosa Piga Undergraduate Computer Engineering Student LSC - IC - UNICAMP http://www.students.ic.unicamp.br/~ra033956

Hello All, RHEL9 deprecated version 1 x86_64 cpus. My old testbench HP workstation has such a version 1 cpu. I've tested install of Rocky Linux 9 and CentOS9Stream but no go upon reboot after install -- kernel panic. Is there a way to recompile the kernel to handle the legacy cpu after install -- via some other live cd, perhaps? Due to the fact I can't reboot after install, I'm not

Hi Anshu, I got a testbench which fails (and segfaults) consistently with an environment (gcc + os) conveniently preserved in a virtual machine. I will confirm that it is gone there and report. Thanks for the fix :) Carlos 2012/12/10 Anshuman Dasgupta <adasgupt at codeaurora.org> > Carlos, > > I committed a fix in r169783. Thanks for catching this. > > However, I could

Hi I have just written a small c programm which reads in speex files and outputs them as asci text numbers. This is necessary as for writing a hw testbench for decoding tests, since thy only read ascii files :-(.I can't read the bitrate properly from the header file. It's allways -1. Please see example below and attached c programm. I wan't to check for a fixed bitrate (8000).

Theora hardware with LEON3 is runinng!!! My video was too slow, then I discovered that the problem was on LINUX! I don't exactly, but I suppose that the time of LINUX Call systems (like fread()) is the problem. If I don't use the linux (like is done on NIOS), I can to decode much faster than the time of exibition! Now we have two points on software (the hardware is the same,

Hi all, I am working on Libtheora. I have built the libtheora, libogg and libvorbis static libraries in vc++6. I'm testing the encoder for theora. I'm running tests on the encoder_example and i get the following errors in command prompt.

Hi Sahana I must admit I'm not an expert in Theora. But the error message "Could not set keyframe interval to 64" might indicate that an attempt to set the keyframe frequency failed. Have a look at the keyframe_granule_shift attribute in the th_info struct. It says: The maximum distance between key frames is 1<<keyframe_granule_shift. So I could imagine that the error might

Hi all, I apologize to not keep you up to date to what is going on with my project. Portavales has worked in a desk behind me and when we go to take coffee we talk about the project. Second I didn't know we have to discuss weekly, it was my fault. I should have read the rules. Sorry. At the first month, I studied the code and the Theora Beta implementation. The code is completely different
