The continued scaling of device dimensions and the operating voltage reduces the critical charge and thus natural noise tolerance level of transistors. As a result, circuits can p...

A conceptually appealing approach to supporting a broad range of workloads is a system comprising many small cores that can be fused, on demand, into larger cores. We demonstrate ...

Fetch gating mechanisms have been proposed to gate the processor pipeline to reduce the wasted energy consumption due to wrongpath (i.e. mis-speculated) instructions. These scheme...
