MAC-based Mapping of Adder Architectures to RRAM Crossbars

This paper presents a comparative evaluation of seven adder architectures mapped to RRAM crossbars using a MAC-based logic style. By analyzing designs across 8- to 64-bit widths, we assess trade-offs in total evaluation cycles, crossbar area, and logical depth. The results highlight Ladner-Fischer and Kogge-Stone adders as the most efficient for high-bit-width applications, offering superior parallelism and scalability in MAC-based in-memory computing systems. Hence, these adder designs can be used as a reference for future works related to the optimization of adders for MAC-based logic style.
