Design of High Performance Fixed Point CORDIC Processor

Abstract:

To meet the demand for aerospace applications, high-speed computing transcendental functions such as trigonometric functions, we design a high-speed full-parallel CORDIC processor. On this basis,combining the optimized algorithm of simplifing pathway and adding-bits high-precision method , the original design has been improved. The experimental results show that improved design reduces hardware overhead compared to adding-bits high-precision design,and improves accuracy compared to fully parallel design. This high-speed fixed-point CORDIC has high precision and is suitable for high-speed applications in computing trigonometric and inverse trigonometric functions.
