I started my project using the CodeComposerStudio speex_C64_test.pjt in speex 1.1.11.1. To build using floating point, I created a new project with the same files and modified ti\config.h to #undef FIXED_POINT. Is there a better way to configure a floating point processor? I have a few TI specific optimizations that could go into the next release. What's the procedure for submitting code?

I'm trying to make a design decision between a TI 6416 or DM642 (fixed point) and 6713 (floating point) platform. The application is a 32 channel speech encoder. (CBR only, 8khz, 8kbps) To get a feel for the computational load, I am running 1 second (50 frames) of voice through the encoder. My profile of the 6416 indicates I'm at 27.4M cycles/channel. I need to get below 720Mhz/32

The majority of a Speex encoder app does fit in a 6713. The 6713 has 8K of L1 and another 256K of memory 64K of which can be configured as L2 cache. (16,32,48, or 64K). One level of TI's website seems to incorrectly indicate only 64K of L2. I turned off MANUAL_ALLOC and have it allocating internal memory using calloc(). I did change the L2 cache to 2 way (32K) and adjusted the heap size to

Jerry, I think that just removing the FIXED_POINT define should be sufficient, though you mind want to turn off MANUAL_ALLOC, because I am not sure if the memory usage is identical for the fixed point build, and the constants in config.h are set for the fixed point build. Are you testing on the simulator, or on an eval board? It does not look like the 6713 has enough memory to hold Speex

Hi, I'm currently working on the TI DaVinci processor, which has an ARM926 processor and a TMS320C64+ DSP in it. I have been using Speex 6kbps (narrowband, quality=2, complexity=1, perceptual_enh=0) on the DSP C64+ side without any issues; the voice sounds very good for such a low bandwidth requirement. However, recently, I tried out the 4kbps mode (changing quality to 1) on the DSP and it

Greetings LLVMers, I would like to add the licensed part of AnghaBench (http://cuda.dcc.ufmg.br/angha/) as an External Test in the LLVM test-suite. We have 128,411 files with their original licenses. (http://www.dcc.ufmg.br/~fernando/coisas/c_files_with_licenses.tar.gz) Each file is a single function, that compiles as is---no dependencies are needed. For instance, the commands below work for each

Hi, I've been trying to get Speex to compile and run on the DSP of TI's new DaVinci System-On-Chip processor, which has both an ARM (ARM926) and a DSP (C64+, based on the C6400). I used the latest code (1.2beta) and followed the example in the speex- 1.2beta1/ti/speex_C64_test trunk to build the Speex library for the DSP. Basically I have a loopback application on the ARM that samples

The attached file contains build files for TI's Code Composer Studio (CCS) for the C54x, C55x, and C6x DSPs. I had intended to post this a couple of months ago, but it took a long time to get around to doing the little bit of cleanup required. This is a file I/O loopback application suitable for running with the CCS simulators, for evaluating memory and MIPs requirements for these

Jerry, Thanks for the response; basically, I need to get just the narrow band working now (maybe use advanced features such as jitter buffer, echo cancellation, VAD, etc in the future); the DSP will do the encode and decode simultaneously as data are available. My main objective is just do a voice application that runs on the ARM side of the DaVinci with the codec running on the DSP side; the

Tried your fixed_generic.h change but that didn't help.

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

Hi Jean-Marc, I have tested Speex in fixed-point mode on my PC without clicking noise. As I mentioned below, I tested Speex in fixed-point mode running natively on the ARM side of the DaVinci without click noise. I only get the clicking noise when running Speex on the DSP side. For the TI C64+ DSP on the DaVinci processor, the TI-specific switches doesn't do much other than defining the

Hi, My company just recently bought a TI DaVinci development board and I'm trying to port Speex to run on it. The TI DaVinci chip has an ARM926 processor and a TMS320C64+ DSP in it. I was able to get Speex somewhat working on a TMS320VC5510 about a year ago but I was wondering is there anything special I need to do to get Speex working on the TMS320C64+ DSP in the DaVinci chip. I

Using Ices2, is it possible to take 2 mono sources that are presented to the soundcard as the left and right channel, and make each of them a seperate mount point? My sources are all low bandwidth mono, and I would love to have a second stream without having to add a second soundcard or a second machine. I looked through the documentation, but I don't recall seeing this specific ability.

Thanks Jean-Marc. Is there a Speex trunk for the C64xx I can use? Or do I have to figure what options to turn on (in configure) when building the library? Thanks.

Hi list! Just wondering, why is * sticking with an mpg123 version from the stoneage? Gentoo comes with 0.59s-r8 and this version doesn't even start. Ik know I could forcibly unmerge mpg123 and install the old version but I guess some day newer versions will have to be supported? Thanks!
