| 1. A system for the efficient use of CORDIC rotators, the system comprising:
at least one first rotator, wherein the at least one first rotator comprises at least one first sign storage buffer;
a first gain device, wherein the first gain device is coupled to the at least one first rotator;
a first limiter, wherein the first limiter is coupled to the first gain device;
at least one bit inverter, wherein the at least one bit inverter is coupled to the at least one first rotator; and
at least one second rotator, wherein the at least one second rotator comprises at least one second sign storage buffer, and
wherein the at least one second rotator is coupled to the at least one first rotator;
wherein the at least one first rotator operates in a vector mode and the at least one second rotator operates in a rotation
mode.
