Flat CORDIC, which was originally proposed to overcome the performance limitations of iterative CORDIC, suffers from the bottleneck of sign prediction prior to the start of computations. Also, this sign precomputation unit has poor scalability. We propose a method for totally eliminating this need for sign precomputation, by directly inferring the directions of rotation from the bipolar representation of the input angle. The proposed engine was implemented using 0.35 micron technology and the resource utilization is reported.
