similar to: running speex on c5505 usb sticki

Hi Randy, Thanks for reply. I have one question though. While compiling the speex (downloaded from http://downloads.xiph.org/releases/speex/speex-1.2rc1.tar.gz), I gave ./configure -enable-ti-c55x option and then built the library through make and make install using cygwin. In this case, I get this error "error: member "bits.o" of archive

Oh my. The c:/Program Files/Speex/libspeex.lib file is a Windows/x86 library file. The code within this files is not C55x binary but x86 binary. Further, the format of a Windows/x86 library file is different from that produced by the C55x code generation tools' archive utility, and that is what the linker is complaining about. As far as I know, there is no pre-developed C55x speex library,

Vijay, I used Code Composer Studio 3.x to directly build everything. There could certainly be issues with the ./configure, make, make install process. There are .pjt files supplied to build in the CCS simulator, so I suggest that you try that. The c55x option is just a compile switch, which deals with the fact that this platform has a 16-bit "byte", among other things. Regards, Jim

Hi, I am an applications engineer for Texas Instruments in the UK. I am trying to port the CELT codec to the C5505, this has HW accelerated FFT engine (http://focus.ti.com/docs/prod/folders/print/tms320vc5505.html). I am having problems with the stack allocation. Do you have any reference code that compiles for the C55x under CCS (code composer studio)? *******************************

Tony, How is this going? Have you been able to get CELT to run on a TI55xx? I am very interested in the % utilization of the hardware and whether multiple instance of CELT on the same DSP are feasible. I look forward to your findings.

Hi, I am working on a project which intends to enable voice communication over zigbee. As the handset node, I am using TI's C5505 ezDSP USB stick. I want to run speex encoder on it. After encode, I intend to send it over CC2520 radio to the backend zigbee network. The C5505 ezDSP has input and output for AIC3204 codec which I am using to give sampled input from laptop (lineout) and playback

Hi, I can see that there has been some effort to compile the SPEEX codec to operate on the TI c54x and c55x DSPs and I am wondering if anyone would be able to update the mailing list with their current MIPs and Memory resource requirements for their c54x and/or c55x compilation? The only estimate I was able to find in the mailing list archive was 42MIPs but I'm not sure if this is an

Hi, Just a couple tips to reduce complexity. First, I think you'd get a good speedup by enabling the PRECISION16 switch (if it's not done already). This (very) slightly reduces quality, but means you convert a lot of "emulated" 16x32 multiplications into 16x16. There are also several routines that would benefit from platform-specific optimizations. There are already

Hi, My name is Jean Quirion and I am a DSP engineer. Currently I am working on a project where it is desired to implement a VoIP solution over a GSM GPRS link. I would like to use Speex as the vocoder for this application. This application would require the Speex encoder/decoder and possibly the pre-processor to run on a low power fixed-point DSP such as a TI C55x. Thus, I am interested in

Hi,I have been trying some different sample rate and bitrate combinations to get a feel for how CELT behaves,too, like Andrew Lentvorski. But I want to use VBR option.I want to ask a question about VBR in CELT codec.Can we use VBR option in CELT ??? "byte_per_packet" variable in code means constant bit rate, does not it ?In this code : bytes_per_packet is constant.len =

Hi; I have a question about speex on TMS320C54X: I have build and run the related project on Code Composer Studio IDE (ver. 3.1) and the male.snd (93.7KB) was its input file and malebits5x.dat (5.85KB) and maleout5x.snd (93.5KB) are output files. What is malebits5x.dat file? if it is encoded file, why I could'nt decode it? Also if maleout5x.snd is output recoverd file why after

Hi Jim, > Build 11169 in SVN works correctly. Good. I'll try not to forget the EXTEND32 from now on. > I have attached a zip file (renamed > .txt) with a patch to bits.c to make the byteswapping for TI DSPs > consistent. Seems like unzip can't read it. Either it's in an unknown format or the file got corrupted. Could simply send as multiple (uncompressed)

Hello, I am interested in using the CELT codec for an embedded project around the DSP C55x family from TI. Is this someone has already done? Which is necessary to do that, which compiler, is there a specific configuration ? Is it necessary to have an Operating system to run the CELT codec ? Is it possible to instantiate several times the CELT codec ? Thank you in

Hello everyone, I have been having trouble utilizing the PLC function (I think). In older versions (0.7.1) a pointer to NULL did the trick, but with code from the tip of the GIT repository, this method causes the codec to crash on the C55x fixed point platform. I have not determined where the crash occurs. I have also attempted to pass in an array of zero's and this creates an echoey, reverby

Jim, Thank you very much for your suggestions. I managed to get the C55x code working on the simulator. I would like to port Speex both on a C5502 EVM and a C5509A EVM. As such, if you can provide me with the details of your port on the C5509A, it would be greatly appreciated. Furthermore, I am looking for some technical documentation on the CELP algorithms. I would like to better

It would be great to get some idea of what chips and DSPs people have tried to compile Speex for, and what success they've had. So, if you've tried Speex on a chip, could you take a second to fill in the following and post it to the list? Chip Name: Speex Version: Floating or Fixed: Encode, Decode, Both or Simultaneous: MIPS (if known): Other comments: Many thanks, Gerv

Hello everyone, I just wanted to see if anyone else is using PLC on the C55x and having success? I am seeing some issues and was curious if I was doing anything wrong/stupid or maybe I have found a bug? I am using: - the CELT library from OPUS 0.9.5 ( I checked the git repo and no check ins have comments about PLC, I assume it hasn't been updated) - FRAME_SIZE: 240 - PACKET_SIZE:

I think I've fixed all occurrences (by adding EXTEND32)
