Paper Abstract

Driven by the excellent properties of FPGAs and the need for high-performance and flexible computing machines, interest in FPGA-based computing machines has increased dramatically. Fixed-point adders are essential building blocks of any computing systems. In this work, various high-speed addition algorithms are implemented in FPGAs devices, and their performance is evaluated with the objective of finding and developing the most appropriate addition algorithms for implementing in FPGAs, and laying the ground-work for evaluating and constructing FPGA-based computing machines. The results demonstrate that the performance of adders built with the FPGAs dedicated carry logic combined with some other addition algorithms will be greatly improved, especially for larger adders.
