Abstract:

The floating-point adder (FPA) basics are introduced in the paper, and the commonly used multi-input FPA is presented. Finally, an improved parallel FPA algorithm has been put forward and analyzed in detail. The operation speed can be improved greatly and the logic resources can be reduced effective ly using this improved algorithm.

Key words: (floating-point adder, multi-input, high-speed algorithm)
