Research and Design of Multibit Binary Adders on Fpga
This paper provides an analysis of the system characteristics and functional capabilities of various types of adders for the high-speed component construction of arithmetic and logical devices in modern superscalar processors. The main features of parallel prefix adders (Sklansky, Brent Kung, Kogge Stone, Ladner Fisher, Han Carlson) and tree-like structures based on incomplete binary adders have been determined in this study. The structures of typical and improved incomplete binary adders have been shown and their complexity characteristics have been calculated as well.
