A review of the present state of art in FPGA-based adders

Adders are the most fundamental arithmetic circuits that are used in processors and play key role in VLSI circuits. Power consumption and speed of these circuits are important quality factors for high performance integrated processing circuits. Floating-point operators, integer multipliers, and modular adders need large adders. On the other hand, Field programmable gate arrays (FPGAs) due to the excellent features such as low power consumption, flexibility, reusability, reasonable cost, easy upgrading, have become a favored platform for VLSI design. At this article recent advances and state of the art techniques in FPGA-Based Adders are reviewed.
