Combining Compiler and Runtime IPC Predictions to Reduce Energy in Next Generation Architectures

Next generation architectures will require innovative solutions to reduce energy consumption. One of the trends we expect is more extensive utilization of compiler information directly targeting energy optimizations. As we show in this paper, static information provides some unique benefits, not available with runtime hardware-based techniques alone. To achieve energy reduction, we use IPC information at various granularities, to adaptively adjust voltage and speed, and to throttle the fetch rate in response to changes in ILP.

Opportunities and Challenges in Application-Tuned Circuits and Architectures Based on Nanodevices

Nanoelectronics research has primarily focused on devices. By contrast, not much has been published on innovations at higher layers: we know little about how to construct circuits or architectures out of such devices. In this paper, we focus on the currently most promising nanodevice technologies, such as arrays of semiconductor nanowires (NWs) and arrays of crossed carbon nanotubes (CNTs).
