[USRP-users] Purpose of 24-bit CORDIC in DDC chain?

I am just analysing the FPGA code of the DDC chain. I just got stuck
when trying to find out the purpose of the CORDIC that comes right after
According to my understanding, the only purpose of the CORDIC is to add
a certain phase increment using an efficient multiplier-free
implementation. The subsequent decimation of incoming, 100 MHz sampled
data (dealing with N210) is then performed via the CIC and Halfband filters.
Is that correct?
