similar to: Errors in speex lib with Blackfin

I'm trying to make a design decision between a TI 6416 or DM642 (fixed point) and 6713 (floating point) platform. The application is a 32 channel speech encoder. (CBR only, 8khz, 8kbps) To get a feel for the computational load, I am running 1 second (50 frames) of voice through the encoder. My profile of the 6416 indicates I'm at 27.4M cycles/channel. I need to get below 720Mhz/32

Hi Jean, First, I would like to thank for the prompt reply. Basically, what I have to do is to run a speex coder/decoder on a Blackfin processor, on top of the microC/OS II kernel. I wish I could use uclinux, since I'm familiar with Linux, but this doesn't depend on me. You said that the assembly code is written for gcc, not for VisualDSP++. Furthermore, in the link you sent me, the

Hi Jean-Marc I'm trying to integrate your speex codec on our custom Blackfin board. The board is not uCLinux compatible and there is no chance that it will ever be. I am using ADI-supplied VisualDSP++ IDE and corresponding toolchain. As long as I am compiling "C"-only version of the library everything is fine. VisualDSP++ produces working library. There is only one not so minor

Hi I'm trying to integrate your speex codec on our custom Blackfin board and without uCLinux. I am using ADI-supplied VisualDSP++ IDE and corresponding toolchain. My question is: Is there anybody who ported speex with enabled BFIN_ASM to VisualDSP++ ? Best Regards, Stefan Voss -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all, I'm trying to run speex on the Blackfin processor. I'm not familiar with programming/compiling/linking at all, but I guess the first thing I need is libspeex compiled for Blackfin, so that my program can use the library functions. I've downloaded the source files (version 1.1.10) from www.speex.org and I've been trying to compile libspeex from within VisualDSP++, but it

> >Actually, you're the first I know using the VisualDSP++ toolchain :-) > I guess that's because speex has pretty big memory footprint. So developers that integrate speex tend to have plenty of RAM and once one has plenty of RAM he could install biggish OS. And between biggish OSes for Blackfin the most popular choice is uCLinux. And ucLinux works best with gnu tools. Something

Most asm statements clobber ASTAT bits (shifts, maxes, etc...) but do declare the register as clobbered. Same thing with CC in a few places. Some places make an attempt at clobbering some hardware loop registers, but it's very incomplete compared with how many asm statements actually use hardware loops.

<speex-dev at xiph.org> Hi all, I'm a begginer with DSP and i need your help and suggestions. I'm trying to use the Speex and a DSP DM642 to implement a solution with voice! I'm using the 1.2 beta 3 distribution and the TI's Code Composer Studio v3.1 simulator. I coosed speex_C64_test.pjt and modified the speex_C64_test.cmd to only use the DM642 external RAM memory. I'm

Hi, My company just recently bought a TI DaVinci development board and I'm trying to port Speex to run on it. The TI DaVinci chip has an ARM926 processor and a TMS320C64+ DSP in it. I was able to get Speex somewhat working on a TMS320VC5510 about a year ago but I was wondering is there anything special I need to do to get Speex working on the TMS320C64+ DSP in the DaVinci chip. I

I started my project using the CodeComposerStudio speex_C64_test.pjt in speex 1.1.11.1. To build using floating point, I created a new project with the same files and modified ti\config.h to #undef FIXED_POINT. Is there a better way to configure a floating point processor? I have a few TI specific optimizations that could go into the next release. What's the procedure for submitting code?

Hi, I think the (small) readme has been accidentally omitted from the tarball. You can get it at http://svn.xiph.org/trunk/speex/README.blackfin Note however that all the assembly is written for gcc, not VisualDSP++.

The majority of a Speex encoder app does fit in a 6713. The 6713 has 8K of L1 and another 256K of memory 64K of which can be configured as L2 cache. (16,32,48, or 64K). One level of TI's website seems to incorrectly indicate only 64K of L2. I turned off MANUAL_ALLOC and have it allocating internal memory using calloc(). I did change the L2 cache to 2 way (32K) and adjusted the heap size to

Jerry, Thanks for the response; basically, I need to get just the narrow band working now (maybe use advanced features such as jitter buffer, echo cancellation, VAD, etc in the future); the DSP will do the encode and decode simultaneously as data are available. My main objective is just do a voice application that runs on the ARM side of the DaVinci with the codec running on the DSP side; the
