Power modelling of multicore systems
Matthew J. P. Walker, Geoff V. Merrett, Bashir M. Al‐Hashimi · Institution of Engineering and Technology eBooks · 2019
The chapter first gives a brief overview of how power is consumed in CPUs before exploring the various energy-saving techniques and power management considerations. A description of different power modelling approaches and applications is presented before top-down, run-time power models are described in detail, highlighting many important, but often-overlooked, considerations. Bottom-up approaches, their accuracy, and methods of improving their representativeness are then discussed and finally, hybrid approaches are proposed.
