General-purpose processors, while tremendously versatile, pay a huge cost for their flexibility by wasting over 99% of the energy in programmability overheads. We observe that reducing this waste requires tuning data storage and compute structures and ...

Scaling the performance of a power limited processor requires decreasing the energy expended per instruction executed, since energy/op * op/second is power. To better understand what improvement in processor efficiency is possible, and what must be done ...

Sixty-four small computers are connected by a network of point-to-point communication channels in the plan of a binary 6-cube. This “Cosmic Cube” computer is a hardware simulation of a future VLSI implementation that will consist of single-chip nodes. ...
