Prenormalization rounding in IEEE floating-point operations using a flagged prefix adder.

Prenormalization rounding in IEEE floating-point operations using a flagged prefix adder.

This paper demonstrates how IEEE 754 floating-point standard compliant rounding can be merged with carry-propagate addition in floating-point unit (FPU) designs by using a novel adaptation of the prefix adder. The paper considers add/subtract, multiply, and SRT divide operations and demonstrates tha...
