High Performance HPOR CORDIC Algorithm

High performance microprocessor has a serious demand for speed and error of transcendental function cal culation.This paper proposes a new modified CORDIC:high precision orderly rotational CORDIC(HPOR CORDIC) algorithm to calculate transcendental function on general-purpose microprocessor which is based on thoroughly research for tradition CORDIC.HPOR CORDIC algorithm can calculate floating-point transcendental function as fast as fixed-point transcendental function and the implement complexity does not change.The algorithm has been used on a SOC soft core which is supported by the National Advanced Research Project.
