Abstract :
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
