A monolithic processor computes products, quotients, and several common transcendental functions. The algorithms are based on the well-known principles of "CORDIC," but recourse to a subtle novel corollary results in a scale factor of unity. Compared to older machines, the overhead burden is significantly reduced. Also, expansion of the functional repertoire beyond the circular domain, i.e., addition to the menu of hyperbolic and linear operations, is a relatively trivial matter, in terms of both hardware cost and execution time. A bulk CMOS technology with conservative layout rules is used for the sake of high reliability, low-power consumption, and good cycle speed.
