The Birth of CORDIC
JACK E. VOLDER
Abstract.
The very earliest history of the CORDIC computing technique—a highly efficient method to compute
elementary functions—is presented. The CORDIC technique was born out of necessity, the incentive being the
replacement of the analog navigation computer of the B-58 aircraft by a high accuracy, high-performance digital
computer. The revolutionary development of the CORDIC technique is presented, along with details of the very
first implementations: the CORDIC I prototype and the CORDIC II airborne digital navigation computer.
