Type: article
Abstract: Dark silicon has recently emerged as a new problem in VLSI technology. Maximizing performance of chip-multiprocessors (CMPs) under power and thermal constraints is very challenging in the dark silicon era. Providing next-generation analytical models for future CMPs which consider the impact of power consumption of core and uncore components such as cache hierarchy and on-chip interconnect that consume significant portion of the on-chip power consumption is largely unexplored. In this article, we propose a detailed power model which is useful for future CMP power modeling. In the proposed architecture for future CMPs, we exploit emerging technologies such as non-volatile memories (NVMs) and 3D techniques to combat dark silicon. Results extracted from the simulations are compared with those obtained from the analytical model. Comparisons show that the proposed model accurately estimates the power consumption of CMPs running both multi-threaded and multi-programed workloads.
