Abstract
A numeric data processor having an execution unit adapted to efficiently execute the complete set of floating point operations recommended by the IEEE Standard for Binary Floating-Point Arithmetic, ANSI/IEEE Std. 754-1985, in full compliance therewith. The numeric data processor is also adapted to evaluate a large set of transcendental functions, including trigonometric, logarithmic and exponential, consistent with the IEEE Standard, without requiring a 'software envelope.' In the processor, special hybrid forms of Volder's CORDIC digital approximator and Meggitt's digital approximator are implemented in a manner so as to require minimal additions or modifications to the form of the execution unit which is otherwise required just to execute the standard floating point operations.
