RE: [Discuss-gnuradio] SDR platform other than usrp with gnuradio

Look at gr-msdd6000 and you will see how an IP based device was interfaced
to gr.  You device will need different controls of course but it should
definitely give you a helping start.  UDP is the chosen transfer mechanism
but TCP is also supported.

Subject: [Discuss-gnuradio] SDR platform other than usrp with gnuradio

Hello,

I am currently working on a custom made SDR platform and trying to use gnu
radio to program it. I understand that I need to write seperate source and
sink blocks to receive and send I/Q samples from and to the device. I was
wondering if anybody in the list could help me in understanding how to
write these block. I suspect I would need to write something similar to
the usrp code. Can you please let me know a starting point on how to write
these blocks? The device I am currently using interfaces with the host
using ethernet and sends/receives base band I/Q samples.

Are there documentations on interfacing gnuradio to SDR platforms other
than usrp. It would be very helpful if you could give some pointers.

-Anand

[Discuss-gnuradio] ADSL Modem

[Swapna Raj]

Hello,

Has anyone ever implemented ADSL using GNU Radio. It should be possible
rite?
I would like to know about the hardware requirements.
Could someone kindly enlighten me about the hardware requirements.

Thank You
Swapna

[Discuss-gnuradio] MP scheduler performance scaling

[Eric Blossom]

I've collected scaling data on several machines and it looks good!

Executive summary:

  All your core are belong to us!


See http://gnuradio.org/trac/wiki/MPSchedulerPerformance for pretty
pictures and links to the code and raw data.

Feel free to send more in.  Use run_synthetic.py to gather it.
We could definitely use data on quad-core intel and quad-core AMD.

Does anyone have access to an SMP machine with more than 8 cores?
If so, can you try running the mp-sched code on it?

Eric
