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

Blackfin inline assembler and VisualDSP++ toolchain
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

Compiling libspeex for Blackfin
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

Compiling libspeex for Blackfin
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

[PATCH] symbian port

I just updated from svn and it looks like there are some errors in the speex.mmp
file. the filters.c is duplicated, and the fft/kiss.c files are still missing..

Compiling libspeex for Blackfin
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++.

Re: Problem with Blackfin assembly optimizations -- bug in fixed_bfin.h / resampler saturation???

when I compile with FIXED_DEBUG enabled, I get an error -- both when make tries to build testenc.o and when I try to link my app against the speex lib:

speex RAM optimising
Greetings to All!
Now I am trying to run speex on TI DSP...
I need only coder+decoder+AEC.
Bitrate 8000bps.
Building with floating point support.
What can i do, to reduce RAM consumption?
I mean very serious RAM optimisations. Deleting not used structure fields, etc...
May be I can do something with alloc...
Help me to determine that it is possible to throw out.

Re: Problem with Blackfin assembly optimizations -- bug in fixed_bfin.h / resampler saturation???
Hi Jean-Marc,
after some problems with getting svn to work here I finally made it. Problem is, you write that I cannot use libspeex and libspeexdsp at the same time now -- because I use a "live" system (mic-in -> speex_enc -> speex_dec -> headphone out) and I can run the AD1836 audio codec on 48 kHz only, I cannot use my program now (because I use speex resampling...)
So I

Blackfin port on Visual DSP, Michael Shatz ?
Hi,
I'm using the Speex codec on my Blackfin-based board,
and plain-C performance is pretty poor.
Decoder is OK (something 25 MIPS for wide-band).
But Encoder is not (wide-band quality 8, complexity 1):
- 162 MIPS with Analog-Devices lib
- 128 MIPS with 1.2beta2 (faster but not working)
I don't worry that much, as it's not the optimized version, and everything
is running in SDRAM.

Problem with Blackfin assembly optimizations -- bug in fixed_bfin.h / resampler saturation???
Jean-Marc, Frank,
I have stumbled across a similar situation regarding optimization.
I seem to have a similar setup as Frank does with a fixed 48khz in and out. The wideband mode and ultra-wideband modes are really what I?m looking for.
I have a test application that reads audio, downsample to 16kHz (or 32kHz), speex encode, speex decode, upsample back to 48kHz, and playback.

VisualDSP++ with enabled BFIN_ASM
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,

Problem with Blackfin assembly optimizations -- bug in fixed_bfin.h?
Hello everybody,
I'm currently trying to run speex on the Blackfin (BF-537) STAMP evaluation board unter uCLinux.
Using 1.2 beta 3, I encountered problems when activating the Blackfin assembler optimizations. Without optimizations for blackfin, i.e. calling
./configure --enable-fixed-point --host=bfin-uclinux
everything seems to work fine.
But when I add the --enable-blackfin-asm flag to
