Abstract
The invention provides a method and system for computing transcendental functions quickly: (1) the multiply ALU is enhanced to add a term to the product, (2) rounding operations for intermediate multiplies are skipped, and (3) the Taylor series is separated into two partial series which are performed in parallel. Transcendental functions with ten terms (e.g., SIN or COS), are thus performed in about ten clock times.
