Hi:
Where can I find documentation for the DSP modules that are present on
the xilinx Zynq SOC?
Thanks a lot!
Cheers,

You are presumably talking about the Zynq on the E31x series of
devices. Took me a second to look up the mapping
between USRP devices and the Xilinx FPGAs they use.
To whatever extent Xilinx IP is used on USRP devices, the documentation
for that IP can be sourced through Xilinx, but
for other bits and pieces (including "home grown" DSP machinery), for
the most part, the source code is the documentation.
There's no separate "structured walk-through" of the FPGA
code--partially because it changes, often considerably, between
FPGA releases, and partially because resources have never been
committed to create such a set of documentation.
There are documents like this:
https://files.ettus.com/manual/page_usrp_e3xx.html
https://kb.ettus.com/Ettus_USRP_E300_Embedded_Family_Getting_Started_Guides
https://kb.ettus.com/Ettus_USRP_E300_Embedded_Family_Hardware_Resources
But no high-level structured walk-through of the FPGA code.
