Power Optimization Technique for VLSI Circuits Using Fine Grain Clock Controller at Leaf Nodes

Authors : V. Vijayakumari and T. Joby Titus

Abstract: Due to dramatic increase in portable and battery operated applications; low power consumption has become the necessity in order to prolong battery life. In Very Large Scale Integration (VLSI) architecture, power consumption is an important criterion that determines the cost effectiveness of end product size. Field Programmable Gate Arrays (FPGAs) are widely used VLSI circuits that can contain even complex system on single chip. Despite their design cost advantage FPGAs impose large dynamic and static power consumption overheads. In this study various design techniques for low power optimization are surveyed. Among them the effective way to reduce dynamic power consumption is observed when introducing fine grain clock gating techniques at leaf node of FPGA architecture. By using the method dynamic power consumption has been reduced 30% at each leaf node of clock network.
