Energy efficient co-scheduling in dynamically reconfigurable systems
Energy consumption is a major issue in dynamically reconfigurable systems because of the high power requirements during repeated configurations. Hardware designs employ low power techniques such as configuration prefetch and reuse. Software designs restrain energy usage by dynamically scaling the voltage of processors. However, when these techniques are implemented in a system, they might be conflicting and thus cancel their mutual benefits, which results in high power consumption and low performance. We propose run-time co-scheduling of hardware and software tasks by using the slack time, which is introduced due to reusing hardware task configurations, for dynamically scaling the processor voltage such that preceding software tasks consume lesser power. At the same time, the reuse of hardware task configurations also result in lower power consumption and higher performance due to fewer number of reconfigurations. The combined effects of hardware configuration reuse and software dynam...
