[Discuss-gnuradio] interfacing DSP and USRP

[miro eshra]

hey guys ,

i am doing a wimax module , the baseband is already implemented on DSP using simulink and i am working on The RF stage on the usrp

but the problem is how can i interface both of them togther i have 2 ideas :

 

I have 2 ideas:

1. is based mostly on software :
• using RTDX channels I think I can get the output from the dsp and save it as .dat file (since USRP only handles raw files)
• Using a Virtual machine like VMware I can operate the linux under windows
• Using a virtual lan between windows and linux the .dat files can be shared between both
• The o/p can be saved in sequential files to prevent the loss of an output due to interface delays
• The o/p rate is 320bits/50 micro seconds
2. is based on hardware :
• Using McBSP socket of DSP with 64 I/O pins on the USRP to make the interface
• but i heard that is one is very risky (specially i am so week in HDL )

so what is the best solution for that and the downsides of each?
