  • Abstract
    A systematic method of implementing a VLSI parallel adder is presented. A family of adders based on a modular design is defined. The design uses three types of component cells, which are implemented in static CMOS. The adder design is formulated as a dynamic programming problem, optimizing with respect to area and time. The result is an area-time optimal adder in the design family. The approach is illustrated by implementing a 66-bit adder for use in a floating-point processor. It is shown how to use the method for implementations in technologies and design styles other than static CMOS
