[PATCH] fix -elf2flt usage for bfin-uclinux
There are multiple problems with the elf2flt usage in the configure script:
- clobbers LDFLAGS
- is used for all targets so breaks non-FLAT targets
- is only used for Blackfin FLAT targets

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

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

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

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

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" +

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

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

many of the same files. Does anyone have any hints on what can be
removed easily that is used only

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

Port to uClinux
Hi,
I'm trying a quick port of this terrific codec to uClinux, a Linux-derivate
for mmu-less systems. I'm particulary interested in the alloc()'s the
library does, and it's stack usage.
In nb_celp.c I found two lines of code doing memory allocation :
nb_celp.c: st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(float));
nb_celp.c: st =

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

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.

samba performance on uclinux embedded system

Thanks for the reply. What about instruction ordering across basic

problem compiling with linux
Dear Jean-Marc Valin,
I tried what you said, to complile just libspeex, as there was
no "configure" file inside the folder "libspeex" I copied it from
parent directory (I guess I am not wrong doing that), ya it configures
well with the command
# ./configure --enable-blackfin-asm --enable-fixed-point --host=bfin-uclinux
but for the <make> command it is
