Hi,

I’m looking at the dsp_core_tx.v and dsp_core_rx.v … May I know what is
the function of cordic_z24.v submodle? is that module for DUC and DDC?
If that is the case, both interpolation and DUC are done in FPGA
(because somewhere i read, at tx side, interpolation is in FPGA and DUC
is in chip).

Br,
