Abstract
The story is told of how the Unified Cordic algorithm came to be developed, starting from an idea in the mind of a student and culminating in a product, a patent, a paper, a motorcade, and an award. Along the way, a unified algorithm for generating the elementary functions and the math co-processor industry in Silicon Valley were born.
