Dark Silicon: From Computation to Communication

In the emerging Dark Silicon era, not all parts of an on-chip system (i.e., cores, Network-on-Chip, and memory resources) can be simultaneously powered-on at the full speed. This paper aims at exposing dark silicon challenges to the NOCS community with an overview of some of the early research efforts that are attempting to shape the design and run-time management of future generation heterogeneous dark silicon processors. The goal is to cover both the computation and communication perspectives. In particular, we exploit computation and communication heterogeneity at multiple levels of system abstractions to design and manage dark silicon processors. The available dark silicon is leveraged to improve power/energy, performance, and reliability efficiency.
