Dear all, I'm Arun, new in this group. and newbie in Linux also. I am working on linphone and I want to compile linphone, but before that I want to compile speex-1.1.10 for uClinux using bfin-gcc. I used these three files : uClinux-dist-2005R3.tar.bz2 bfin-gcc-3.4-2005R3.1.tar.gz speex-1.1.10.tar I sucessfully compiled and installed bfin-gcc, and uClinux. Now when I use the "./configure" it is run sucessfully. After that I use &qu...

Hi Robin, I'm happy to talk with the blackfin uClinux guru ;-) After hours of fighting with MinGW, which could not run autoconf and automake on my windows... I finally wrote the makefile myself and got Speex compiled with bfin-elf-gcc / bfin-elf-ar. The ELF format is also used by VDSP, so I can link. But this was useless anyway, as the calling conventions are different... Although uClinux is great and the GCC are very good tools, it's not an option for me, because I need: - a small RTOS, where I can control hardw...

I have modelled these register classes without knowing anything about what the code generator expects.

...verybody, 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 the above call, a speech signal which has been passed through the codec is cleary disturbed (for me, it sounds like the long term prediction (voice pitch detection) fails -- the signal sounds like the speaker h...

Yes, have a look at the _bfin.h, _sse.h and _arm.h files to get an idea of what's useful.

Hello, I'm trying to use speex for implementing a VoIP demo application using linphone on an embedded system. At the moment I'm not really able to do real time encoding, and thinking about making an assembler port for speex to the AVR32 architecture. The AVR32 is a new hybrid MCU/DSP fixed point processor running at 120Mhz in my application. Does anyone have experiences/info about the

Greetings everyone, I'm trying to compile asterisk for an AVR32 (Atmel NGW100). Buildroot for AVR32 already has the asterisk package, though it has bugs. Firstly it tries to apply a patch for 1.2 on a 1.6, but deleting the contents of the patch file did the trick. Now, the problem is making asterisk. The first error is because asterisk needed to be ./configure:ed. Trying to just do

Hi, I've been working on a Blackfin backend (llvm-3.6.0) based on the previous one that was removed in llvm-3.1. llc generates codes like this: 29 p1 = r2; 30 r5 = [p1]; 31 p1 = r2; 32 r6 = [p1 + 4]; 33 r5 = r6 + r5; 34 r6 = [p0 + -4]; 35 r5 *= r6; 36 p1 = r2; 37 r6 = [p1 + 8]; 38 p1 = r2; p1 and r2 are in different register classes.
