USRP2's FPGA resources

GNU Radio
1

Hello,

I would like to ask if someone could tell me how much of the USRP2’s
FPGA
resources are consumed by the firmware (the ZPU) and the FPGA (DSP
operations) images. Or, in other words, how much of the resources is
free.

Thanks!

Edu.

Detailed answers to that change from rev to rev, but roughly 30% of the
logic resources are available on the USRP2, with the current
images.

Detailed answers can be had by running the current FPGA and Firmware
codebase through the Xilinx tools, and getting the stats
from those tools.
