A unified view of CORDIC processor design
Shaoyun Wang, Vincenzo Piuri, Earl E. Swartzlander · 2002
CORDIC processors are powerful computing systems for applications involving large amount of rotation operations or for evaluating several elementary functions. In this paper, a unified view of the different architectures proposed in literatures is presented. The goal is to provide a wide spectrum of architectures, a coordinated and comprehensive design methodology, and the main figures of merit characterizing architectures' performance and complexity. This provides the basic guidelines to the designer for an optimal choice of the architectural approach with respect the specific requirements and constraints of the specific application.
