In recent years, power consumption as a figure of merit for field programmable gate arrays (FPGAs) has grown in importance. Because of the increasing use of FPGAs in high-volume and embedded applications, power dissipation and energy efficiency are at the forefront of the system designer’s concerns. As high-volume applications are becoming more battery-operated, the importance of energy is growing to allow for longer battery life.

This paper explains how FPGA programmable architecture, such as the Xilinx Virtex-5, can improve the design of power-efficient systems.
