similar to: Optimized Codecs for Blackfin DSP

Hi, Thank you. I will try it. Do you know some G.72x, GSM, and iLBC optimized for Blackfin ? I mean open source. -- Best regards, Miroslav mailto:miro@space-comm.com Wednesday, March 23, 2005, 9:05:11 PM, you wrote: JMV> Hi, JMV> As far as I understand, the last patch (for TI C5x) I merged in SVN also JMV> allows Blackfin to work, but I haven't

Dear Jean, The source code for G.729 can be download from ITU for free. Also, some developer can do yourself as open source G.729 codec without any help. In this case each who use this codec which source code is free and open source must pay, but not to the developer.

My problem is that we are not so familiar with Blackfin DSP. Concerning of patent issues, you are not right. The patent is for their using, not for the source code. Every one

Hi, As far as I understand, the last patch (for TI C5x) I merged in SVN also allows Blackfin to work, but I haven't tested.

Hi, I would like to find some way for hardware coding instead software (using the Host CPU). Are there any PCI boards just with codecs (DSP) or other way?

Hi, I would like to ask you for advice how to solve the following case: I have a client (who happened to be my friend) and I have convinced him that the IP PBX solution is much better than the conventional telephone centrals (PBX). At the beginning he wanted to buy PBX Panasonic, but at this moment he is waiting for my decision. Because at the moment we are not so deeply familiar with these

Hi, We have potential client which would like to offer to him VoIP solution for 2000 subscribers (SIP based Phones) and 2 x PRI ISDN interfaces to the PSTN. In the next stage the subscribers will be increased up to 13,000. Because I am not haven't done similar big project I don't know how to calculate the price. The one way is using number of subscribers and the other is using PSTN

Hi, I can't find anywhere on the Asterisk web the license terms for commercial use of Asterisk software. Do I have to pay something (and how much) if I want to use the Asterisk in our IP PBX solutions? Best Regards, Miroslav Nachev COSMOS Software Enterprises, Ltd.

Hi, We have a case where we need of 16 x FXS, 12 x FXO and 1 x E1. To do this using Digium products I need of 8 PCI slots. This is not possible to be done in one computer and that's why I try to start using TDMoE. Unfortunately all my tries are without success. The network is crashed everytime. Can you give me some ideas/suggestions how to solve this case? Best Regards,

Hi, Can I use HT-486 as VoIP Gateway together with Asterisk? Are there any success experiences? -- Best Regards, Miroslav Nachev

Hi, > Thank you. I will try it. Do you know some G.72x, GSM, and iLBC > optimized for Blackfin ? I mean open source. Outside of GSM full-rate (13 kbps, poor quality), none of these codecs can ever have open-source implementations due to patent issues. In the case of iLBC, you can have a free (not open-source) license if you register, but it's only for the floating-point version AFAIK.

I saw a thread in the list archives about a speex port to TI 55x DSP. Wondering how that worked out (is working out)? Also wondering if there is a source archive for it, or if the patch in the email archives is still current, or if there's been updates. Any info appreciated. Thanks Paul

Jamey, There is a previous posting in the speex archives with a link to the dsp c5x patch. Archive link: http://lists.xiph.org/pipermail/speex-dev/2004-October/002847.html Patch link: http://lists.xiph.org/pipermail/speex-dev/attachments/20041029/facb8c73/spee x-1.1.6-jeh1-0001.bin But that patch is very different (much smaller) then the dsp c5x patch at

Hi, I would like to make a call and then when I am connected to the destination to transfer the call to my coleague in the office. When we receive the call it is easy using "#". But when I am the originator the "#" doesn't work. Can you give me some suggestions? Best Regards, Miroslav Nachev COSMOS Software Enterprises, Ltd. Tel: (+359-2)

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

Hi, When we use BudgeTone where the DTMF is set to "via RTP (RFC2833)" all the DTMF functionality of Asterisk is working OK. When use Cisco 7960 the transfer is working OK, but when I try to "remote pick-up the call" through '*8#' I can't do that because the Cisco Phone start busy signal. How can I start using all DTMF features using Cisco Phone? Best

If something isn't free software, it's not open-source either. There may be exceptions, but I have yet to

Hi All, Is it correct to say that by design, asterisk wont make use of any cards hardware dsp capabilities ? I don't think that any of the hardware cards currently supported have any dsp capabilities, but I wanted to know if for example, in the future a driver was written for a card that did have dsp capabilities, would asterisk be able to make any use of it ? I am only just starting out

Hi, I'm using the Speex codec on my Blackfin-based board, and plain-C performance is pretty poor. Decoder is OK (something 25 MIPS for wide-band). But Encoder is not (wide-band quality 8, complexity 1): - 162 MIPS with Analog-Devices lib - 128 MIPS with 1.2beta2 (faster but not working) I don't worry that much, as it's not the optimized version, and everything is running in SDRAM.
