for voip application - do I need to install sys/bios 6?

tharangini chinnadurai

1. I already have a project with NDK+ c6747_audio_edma.prj and using this, I can receive voice from LineIn and transmit this voice out to another PC via UDP protocol (via ethernet cable). Now, I hear tic sound in the background and I doubt that there might be some other task preempting from sending out at the correct timing. To see what is happening with the task, I need the Exec graph- but I have dsp/bios ver5 installed. Do I need to install sys/bios ver 6 to use Exec graph?

2. Apart from this, do you think I should stick with dsp/bios 5 or should I migrate to sys/bios 6 for this voip application?

3. Could you pls send some examples using NDK + sys/bios 6 and also another example having c6747_audio_edma.prj (which is one of the example projects from TI) using sys/bios6?

I mean by " NDK + sys/bios 6" - that is, NDK, client example code, for example where I can view the threads using Exec Graph. At the moment, the NDK example code doesnt have .cfg to view using Exec graph. It has only .tcf

Hi Tharangini,

I don't know if switching from DSP/BIOS to SYS/BIOS is the right thing for you. That all depends on your application.

The NDK (TI's TCP/IP stack) works with SYS/BIOS and can be obtained from here.

Let me check to see if there is another VoIP example application.

Hi Tom, Thanks for your reply. I am using UDP protocol of NDK stack. Any help with an example voip application would be simply great! thanks in advance.

We do not have any example of VOIP using NDK and UDP.
