Volder), [1] [2] Linear CORDIC, Hyperbolic CORDIC (John Stephen Walther), [3] [4] and Generalized Hyperbolic CORDIC (GH CORDIC) (Yuanyong Luo et al.), [5] [6] is a simple and efficient algorithm to calculate trigonometric functions, hyperbolic functions, square roots ...
Jack Edward Volder (1924-2013 [1]) was an American electrical engineer.He is best known for inventing the CORDIC algorithm.. Jack Volder was born in Fort Worth, Texas.During World War II, he served as a B-24 flight engineer. After the war, he studied electrical engineering, graduating from Texas Technological College in 1949. He first joined Allis-Chalmers in Milwaukee, Wisconsin before ...
Volder's solution instead suggests to note that the rotation vector is in the upper quadrants and therefrom perform an initial rotation by 9 0 ∘ 90^\circ 9 0 ∘ (subtracting 9 0 ∘ 90^\circ 9 0 ∘ from the remaining rotation) by modifying the provided coordinates: X 0 = − Y X_0=-Y X 0 = − Y, Y 0 = X Y_0=X Y 0 = X; Example (figure provided)
Year 2009 marks the completion of 50 years of the invention of CORDIC (coordinate rotation digital computer) by Jack E. Volder. The beauty of CORDIC lies in the fact that by simple shift-add operations, it can perform several computing tasks such as the calculation of trigonometric, hyperbolic and logarithmic functions, real and complex multiplications, division, square-root, solution of ...

1959 by Jack E. Volder. It was developed to replace the analog resolver in the B-58 bomber's navigation computer. (from Wikipedia) • Used in Intel 80x87 coprocessor and Intel 80486 • Commonly used for FPGAs • Complexity Comparable to Division
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 ...
Burchard de Volder was a Dutch physicist and philosopher who taught at Leiden University and corresponded with Leibniz. He established a physics laboratory and attracted many students, including Boerhaave.
