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,
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++.

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

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

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

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

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

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:

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

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.
If I remove

[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

Hi Jean-Marc,
didn't get a reply to my last post (see below) -- do you have no idea what happens here?
After some more tests, I disabled the DIV32_16 Blackfin optimizations and now get good quality on the Blackfin. But when I have overdrive on the input, things become very bad -- I'm not sure if this is really a filter stability issue like I wrote some weeks ago.
I use the speex

porting flac to uClinux ?
hi
I am trying to port the flac decoder library to
uClinux which runs on blackfin processor
I saw a directory contains ASM files inside
src/libFLAC/ia32.
I need to know, whether these files are to be
converted to corresponding blackfin ASM routines in
order for the decoder to work.
