Subject: [oc] Complex multiplier implementation via CORDIC ?

Dear opencore elites,

  I have a problem about CORDIC to consult. Now we have input signals
(a+bj) and (c+dj). We would like to compute the product of two signals
instead of complex multiplier for area and power etc. reduction. As I know,
CORDIC could deal with the problem. Suppose that the product of two signals
is (ac-bd)+(bc+ad)j. How could we utilize the CORDIC to compute the real
and imagary part (ac-bd), (bc+ad) respectively ? Does it firstly translate
the a+bj and c+dj to R1exp(jtheta1) and R2'exp(jtheta2) ? Appreciate for
your any comments or references.

All the best,

Nanson
