similar to: Reg. getting codewords from codelengths

hello all, we are developing and porting vorbis1decoder on a 24 bit platform. in the process we came across somedoubts about node bytes and leaf words. from the specification we got that we are arranging the huffman codeword tree into an array. the nodebytes are the number of bytes that are required to represent a node and leafwords are the no. of bytes required to represent the leaf i.e the

Hi, We are porting the Ogg Vorbis fixed point decoder to a 24 bit fixed point precision processor. We are trying to reduce the number of cycles for MIPS optimization. In this process we observed that most of the songs do not have "maximum codeword length" greater than 24 bits. We are planning to reduce most of the double word operations (in our case 32 bit data is stored as double

hello, does anybody know whether the codewords have a special meaning? whether they have a different influence like the quantization matriy in jpeg? e.g. do lower or the first entries have a greater influence than the last or higher codewords? thanks gerald

Hi Sebastian, It boils down to this: The previous heuristic solver could return infinite cost solutions in some rare cases (despite finite-cost solutions existing). The new solver is still heuristic, but it should always return a finite cost solution if one exists. It does this by avoiding early reduction of infinite spill cost nodes via R1 or R2. To illustrate why the early reductions can be a

Hi Lang, I'm surprised about the fact that you omit R1/R2 reductions in some cases. Can you give a more detailed description of the bug (e.g. a PBQP dump)?

Dear gluster experts, We have encountered a severe performance issue related to quota feature of gluster. My underlying fs is lvm with xfs format. The problem is if quota is enabled the io performance is about 26MB/s but with quota disabled the io performance is 216MB/s. Any one known what's the problem? BTW I have reproduce it several times and it is related to quota indeed. Here's the

Hi Sachin, llvm-dev, I've just committed a new PBQP solver which, among other things, should take care of this bug. Please let me know how it works out for you. Cheers, Lang.

I was just somewhat curious as to what lossless compression is used... is it just huffman? Tony Arcieri --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/

hi kuhlen, what you said is correct. i am talking about how you are going to arrange these codewords into an array, i.e. in the function _make_decode_table. there he uses node bytes and leaf words for memory management. i got a 24 bit platform. so if i assume that max. codeword length that could be possible as 24 bits can i allocate a memory of (2 * used entries - 2), to arrange the whole tree in

Hello folks, The codebook infrastructure for Vorbis is now well underway. This is it! The last piece needed for *real* bitstreams. To that end, I have a decent VQ codebook generator running. I was originally using some farily typical merge/split algorithms and then decided that the right way to do this was to model a VQ codebook as an m-dimensional set of bubbles (like a foam). I know there

Hi radeonhd, nouveau, mesa3d developers, Firstly, thank you all very much for all the important work you do. I've been working as a part-time developer on the "Spring RTS" project (open-source game engine) which runs on linux (and other os). Some time ago I tried the engine on the open-source ATI radeonhd driver, which I understand to be partly based on mesa 3d, and all textures

Hi, I am trying to implement ogg vorbis real time decoder on SHARC ADSP 21364 processor. I am writing my own version of the decoder using the documentation vorbis_I_spec.pdf from xiph.org. However I am facing certain hurdles in floor curve decoding during audio packet decode. In the spec it says that [cval] = read from packet using codebook number [so and so] in *scalar context*.(page no 43).

This series of patches makes Xen pass a (somewhat) valid device tree to dom0. The device tree for dom0 is the same as the one supplied to Xen except the memory and chosen nodes are adjusted appropriately. We don''t yet make use of the device tree to map MMIO regions or setup interrupts for the guest and we still include the UART used for Xen''s console. Note that loading Linux

Hello, I am attempting to use smoothScatter to plot a heatmap of locations of events in an x-y axis. When I plot the heatmap without passing xlim and ylim parameters, it fills the plot area but the perspective is a bit skewed. I would like to standardize these plots to a uniform window size that does not depend on the range of values in the dataframe. However, when I resize the plot using xlim or

Hi all, I''d got the impression that puppet didn''t care about ordering - ie. the ordering of imports and includes related to calling them in the manifest. Lately I''ve had big trouble getting puppet to accept that I require some resource that I _have_ defined elsewhere in the manifest. To explain it, here is a simplified example: site.pp: -------- import

During the interesting interview that binaryfreedom has made with Monty and Jack, Monty mentions cascading, a feature that will be added, quote: "Cascading is the ability to make multiple passes through the frequency spectrum, iteratively filling in more detail, like a progressive jpeg". What are the advantages of something like this - does this generally improves quality or is it used

I''ve been searching around but haven''t found a way to do something like a purge with augeas. If you have a file such as [iniheader] entry1 (managed by puppet) entry2 (not managed by puppet) And you want to add ''entry3'' as well as removing anything not managed by puppet in that subsection then you currently do not have this capability. Is this correct? I

I have been using pxelinux with Intel 850 1.7 Ghz P4 motherboards using 10/100 ethernet switches for about a year in a multichannel visual generation system. We are shifting to SuperMicro P4SAA 2.8 Ghz P4 motherboards with onboard gigabit ethernet and gigabit ethernet switches. Put are hung up because the diskless slave nodes will not load the (Linux) kernel from the master 2.8 Ghz computer.
