  • Double-step CORDIC processing for conventional signed arithmetic with decision postponing
    Patent number: 8775493
    Abstract: A double-step CORDIC algorithm is implemented for conventional signed arithmetic using multiple iteration stages in which at least one stage implements decision postponing, in which the decision for each stage is delayed until the next stage. In one implementation, the decision for the previous stage is implemented in parallel with the execution of CORDIC equation functions for the current stage. Implementing the double-step CORDIC with decision postponing algorithm can increase the speed of the CORDIC function compared to prior-art CORDIC implementations.
