N2 - Carry computation is a major performance bottleneck in many high-performance digital applications. Many of the digital application use adders implicitly or explicitly in their internal architecture, and with use of Filed Programmable Gate Arrays (FPGA) as an implementation platform, the choice of an adder becomes very crucial. Thus, it is important to carefully select an adder architecture that will maximize the overall system performance at early design stage. In this paper, we investigated the implementation of five adder architectures (Ripple-Carry, Carry Look-Ahead, Brent-Kung, Kogge-Stone and Han-Carlson) on Virtex-5 FPGA that is built using the 65nm process technology. The presented results are of importance since they give an early direction for proper adder selection and integration in the design.
