Hi all, I'm attempting to convert all the pointers to arrays the mdct_backward function so it can be partitioned off for a hardware implementation. Although this code is quite short I'm finding it a little tricky. As it stands, mdct_backward is passed values by reference i.e. void mdct_backward(mdct_lookup *init, DATA_TYPE *in, DATA_TYPE *out) o my modified version starts void

Hi, I'm trying to determine how the frequency data that is passed to the MDCT, and output time domain data obtained from the MDCT, is changed when setting #define MDCT_INTEGERIZED For instance, the trig array, for a size 256 window begins 1.000000 0.000000 0.998795 -0.049068 0.995185 -0.098017 if INTEGERIZED is set, then it begins 16384 0 16364 -803 16305 -1605 which is simply a left shift

If You want to compile vorbis libraries under win32 environment you can experience some problems: 1) If you unzip vorbis libraries, you will have 3 directories: "libogg-1.0", "libvorbis-1.0" and "vorbis-tools-1.0". You need to rename them to "ogg", "vorbis", "vorbis-tools". Otherwise batch files or even dsp project files, won't work.

i'd like to know if there is any plan or existing work to add a Aho's trig language like code generator generator? "...If you are starting a new port, we recommend that you write the instruction selector using the SelectionDAG infrastructure." any other things i should know before i write one? thank you.

Hello All, I cant seem to do a trig regression in R. The equation is as follows : y = a+b*(sin((2*pi*x/360) - c))^2 a, b, c are coefs that I want. y, x are input vectors. The equation I put into R: lm(y ~ sin(2*pi*x/360)^2) This equation is missing the c and I dont get the right answer. Also, I dont know how to plot the lm over the x values instead of the indices. Any help is sincerely

We are slowly making the code generators more and more automatically generated as time goes on. The SelectionDAG infrastructure is mean to support exactly this (perform Tree or DAG pattern matching on the optimized DAG

i'd like to know what progress you guys have made (not on cvs?). i don't want to re-invent wheels, and the existing many code generator generators. i am evaluating many possbile code generation libraries. at present i give me preferrence to "Prop": http://www.cs.nyu.edu/leunga/www/prop.html and it's portable too. are there any other good library you could recommend?

Noone is currently working on automating the pattern matching generator process yet. Before doing that, there are a few changes we want to make to the SelectionDAG interface. In particular, right now, the selection process basically works like this: #1.

the proposed architecture (chris) doesn't seem to attack the phase ordering problem. through having independent instruction selection, instruction scheduling, and register allocation phases faciliate a modular design, but i believe the phase-coupled code generator generator high quality code on many architectures. espeically in the embedded system like a media/dsp processors with very limited

Hi vorbis-dev, I'm investigating the mdct* function in libvorbis and writing a small client program to test it. I found that I have to set ARRAYSIZE when mdct_init(lookup, ARRAYSIZE) to minimum value of 62 otherwise it will segfault with mdct_backward. Is there any lower limit or it is more likely that my code has bug? Thank you very much, Pattara -- Please avoid sending me Word or
