ABSTRACT
<p>Power gating reduces static power by either disabling whole units or dynamically resizing units to meet application demands. The Loop-Directed Mothballing technique lets users power gate execution units by recording utilization of individual units in loops, and by power gating units according to two utilization thresholds. LDM offers on average 10.3 percent total power savings with low performance loss.</p>
