FPGA mo

Hi all,

I’m not sure whether to post this to GnuRadio or to USRP-users, so I
post it here.

We’ve started a project to implement a custom SDR hardware (which we
plan to open-source later) and we want to reuse as much of USRP FPGA
code as possible. But it will require a good deal of customization as
well.

So, we’re looking for an advice on how to structure our relations with
the upstream (i.e. GnuRadio/USRP) the best way. I.e. where should we
place our code and how to ensure our code will be accepted to the
mainline, etc?

I can’t answer the questions about where to best place the code in the
tree, but maintaining compatibility with the
UHD wire protocol and API would really help make it easy to integrate
into Gnu Radio. Matt can comment on
UHD licensing for projects like this, I’m sure.

To make it more clear - we intend to keep all VRT/UHD related FPGA
code in place and just replace/change interaction with RF part. May be
we’ll have to slightly extend VRT/UHD code for our specific purposes,
but it will be minor changes.

In other words - all our changes will be to support a new platform
seamlessly with existing UHD code.
