similar to: Speex for the Intel XScale with WMMX.

Hi, I'm not even sure what WMMX is, so I have no idea how to use it. For sure you would at least need to write some assembly. As for the current inline assembly parts (for the ARMv4 arch), you would need to convert them to VC++. It shouldn't be too hard, just push/load the registers at the beginning and then save/pop at the end. It's just the small macros (in fixed_arm4.h) that you

Most of the WMMX instructions have MMX/SSE equivalents, plus there are a few other interesting functions. We have been thinking about doing WMMX optimizations of the various speex asm functions,

Hello Cesar I'm using Speex on a PPC2002 and PPC2003 with no problems. For tune-up remember to define the FIXED_POINT macro in Project->Settings in eVC. With this setting you ought to be able to at least decode in realtime while using debug-mode. Kind regards Bjoern D.

Hi there, sorry for troubling everybody once again, I've got a problem rewriting Sarkar's function for rewriting the tick locations in a logaritmic way (s. http://lmdvr.r-forge.r-project.org/code/Chapter08.R): His example works for log 2 but I need log e (natural logarithm). My problem is that if I replace 2 with "e" (using paste()), I get the error message that the location

Good afternoon, I am trying to create a plot where the bottom and top axes have the same scale but different tick marks. I tried user-defined xscale.component function but it does not produce desired results. Can anybody suggest where my use of xscale.component function is incorrect? For example, the code below tries to create a plot where horizontal axes limits are c(0,10), top axis has ticks

Hi, I am working on performance tuning of opus library on ARMv5E platform. Our marvell soc also have wmmx simd coprocessor for speed optimization. Now, I have profiled quant_all_bands() function and it seems its taking almost 51% time of whole frame decoding. I have tried to find out the hot spots parts in this function and it seems quant_all_partition() function is taking too much

Hi, Does samba require gawk, awk, perl, cc to compile? Or is it possible to just use the gcc compiler to build it. I want to build samba on xscale processor which has aminimal file system with native gcc compiler. It doesn't has perl or gwak etc. -Thanks, Rajesh

Hello! I posted a feature request at lattice page on r-forge at https://r-forge.r-project.org/tracker/index.php?func=detail&aid=1127&group_id=638&atid=2570 , but I decided to duplicate it here to make sure that I understand everything correctly. I would like to slightly change the way my plot axis labels look alike based on custom extra arguments to xyplot and bwplot. Right now these

Hi all, I've got a 400MHz XScale-PXA255 board, and I want to stream voice from it over a network connection at 28.8baud. This calls for a capable voice encoder which can encode at about 24kbps. I was damn happy when I found Speex and said goodbye to MP3 :) However, i'm still a long way from realtime encoding using speexenc, is this possible? Using the fixed point math option in

Dear OpenSSH developers, I tried porting OpenSSH-4.3p2 to arm-linux (IXP425 Xscale platform) using openssl-0.9.8b and uClibc. This on the snapgear 3.2.0 distribution. It all compiles without problems, but when i run any openssh executable it will always show output similar to the following: # ssh sh: /usr/bin/ssh: No such file or directory # I checked for the libraries, they are all in /lib.

I'm developing a Personalized system of news audible for PDAs(Pocket PC and Palm OS), I have somes PDAs with differents processors(Samsung (2410) 266 MHz, Intel Xscale PXA 250 to 200 and 400 MHz, OMAP1510) with Pocket PC 2002 and 2003, and Palm OS 5 operating system. I offer myself to test any application of speex that runs in these machines, only you must send me the source code. Regards.
