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

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,
Stefan Voss

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

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

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.

Errors in speex lib with Blackfin
Hello!
I'v downloaded speex lib 1.1.11.1.
I am trying to port speex lib to Blackfin processor.
I am using VisualDSP++ 4.0.
If I am compiling source codes with using floating point everything
ok.
When I am compiling with FIXED_POINT defined everything's ok and code
works about two times faster.
But when I am defining BFIN_ASM I am getting several compiling errors
in Blackfin assembler

Patch for Analog Devices compiler & fixed-point AGC
Hi Jean-Marc,
As I told you, bank is a reserved keyword in Analog Devices compiler for
Blackfin architecture.
So we need to change the variables named bank to something else.
Here's a patch that changes bank to bnk in the 3 concerned files.
(Hope the format is OK)
About my previous problems with the Blackfin:
-> strange block repetition that could be cancelled by the AEC

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

Hi,
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:

Noisy sound quality with Blackfin in WB-mode
Hello all,
I'm testing the Speex codec for my diploma thesis on a BF-533 Blackfin under
uCLinux (2005R3 RC3 release). I successfully compiled the Speex (1.1.11-svn)
and I can encode/decode wav-files on my STAMP-board using the speexenc/speexdec
sample apps. But I encountered that the decoded file sounds strange/noisy, when
compiling with "--enable-blackfin-asm" +

Speex Decode only on Blackfin
I am looking into using speex for a decode only application on the
blackfin. Encoding would be done elsewhere with voice phrases loaded
into FLASH. Code space is a premium in the blackfin app, and mips to a
certain extent
1) The source code seems to be codec-centric with encode and decode in
many of the same files. Does anyone have any hints on what can be
removed easily that is used only
