Reducing Energy In Fpga Multipliers Through Glitch Reduction, Nathaniel Rollins, Michael J. Wirthlin
Reducing Energy In Fpga Multipliers Through Glitch Reduction, Nathaniel Rollins, Michael J. Wirthlin
Faculty Publications
Sponsorship: NASA Earth Science Technology Office (ESTO). While FPGAs provide exibility for performing high-performance DSP functions, they consume a significant amount of power. For arithmetic circuits, a large portion of the dynamic power is wasted on unproductive signal glitches. Pipelining can be used to significantly reduce the unproductive power wasted in signal glitches. This paper presents a methodology for estimating the amount of power consumed by glitches and applies this methodology to non-pipelined, pipelined, and digit-serial multipliers. This glitch estimation is used to evaluate these multipliers using four energy metrics: energy per operation, energy delay, energy throughput, and energy density. …
Minimising Power Losses In Distribution Systems With Distributed Resources, An D. T Le, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich
Minimising Power Losses In Distribution Systems With Distributed Resources, An D. T Le, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich
Faculty of Engineering and Information Sciences - Papers: Part A
Attempts to reduce electricity cost, together with improving the efficiency of distribution systems, have led power utilities to dealing with the problem of power loss minimisation. Although losses in the system can never be entirely eliminated, they can be controlled and minimised in several ways. Research conducted in the last few decades has proven that an inclusion of Distributed Resources (DR) into distribution systems considerably lowers the level of power losses. Moreover, the choice of DR is even more attractive since it provides not only benefits in power loss minimisation, but also a wide range of other advantages including environment, …
Dynamics Of A Hydro-Wind Hybrid Isolated Power System, M Aktarujjaman, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich
Dynamics Of A Hydro-Wind Hybrid Isolated Power System, M Aktarujjaman, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich
Faculty of Engineering and Information Sciences - Papers: Part A
Implementation of Distributed Generation (DG) can improve power quality and reliability, and guarantee continuity of power supply. This paper addresses the issue of continuity of power supply especially for isolated communities. A part of a network can be electrically isolated from the main grid when the grid fails to supply power due to a fault in the network or unavailability of power generation. In this paper, a mini hydro-wind hybrid power system is considered, and operation and control of the hybrid system during connecting it with the grid as well as its operation in the isolated condition are investigated. The …
Simulation And Economic Evaluation Of Coal Gasification With Sets Reforming Process For Power Production, Zachary Hoffman
Simulation And Economic Evaluation Of Coal Gasification With Sets Reforming Process For Power Production, Zachary Hoffman
LSU Master's Theses
Increasing natural gas prices have raised interest in alternate energy resources. Popular belief in the connection between carbon dioxide emissions and global warming has motivated the search for a technique to isolate carbon dioxide from combustion stack gases. Coal gasification with SETS reforming has been proposed as a solution to both of these issues in that it provides an alternate energy source and 100% carbon dioxide sequestration. The purpose of this research is to simulate this process using AspenPlus to perform the rigorous material and energy balances. The results of this simulation are used to carry out a complete economic …
