Abstract [en]

The intrinsic computational efficiency (ICE) of silicon defines the upper limit of the amount of computation within a given technology and power envelope. The effective computational efficiency (ECE) and the effective computational density (ECD) of silicon, by taking computation, memory and communication into account, offer a more realistic upper bound for computation of a given technology. Among other factors, they consider how distributed the memory is, how much area is occupied by computation, memory and interconnect, and the geometric properties of 3-D stacked technology with through silicon vias (TSV) as vertical links. We use ECE and ECD to study the limits of performance under different memory distribution constraints of various 2-D and 3-D topologies, in current and future technology nodes. Among other results, our model shows that in a 35 nm technology a 16 stack 3-D system can, as a theoretical upper limit, obtain 3.4 times the performance of a 2-D system (8.8 Tera OPS vs 2.6 TOPS) at 70% reduced frequency (2.1 vs 3.7 GHz) on 1/8 the total area (50 vs 400 mm2).
