High-performance divider using redundant binary representation

A high-performance iterative quadratic convergence fixed-point, real and complex number, divider circuit using a previously developed redundant binary inner-product processor core is presented. The intermediate quotient coefficients are kept in redundant binary (RB) form without converting back to normal binary numbers. A unified multiplier using redundant binary representation for both signed and unsigned numbers is investigated. Goldschmidt and Newton-Raphson division methods are compared and the mathematical equivalence of these two methods is provided.
