Parallel scaling-free and area-time efficient CORDIC algorithm
Matteo Causo, Ting An, Lírida Naviner · 2012
This paper proposes an innovative version of the CORDIC algorithm by introducing a parallel rotator able to rotate for more than one micro-rotation angle per time. Methods for choosing the consecutive micro-rotation angles pairs as well as the most appropriate configuration for the proposed approach, are here reported. Simulations have been performed for a 16-bits architecture in order to demonstrate how to produce efficient trade-offs between complexity and accuracy. Considerations about Angular Domain extension are taken into account.
