Run-time estimation of system and sub-system level power consumption
Electronic systems’ power consumption has been a real challenge for Hardware and Software designers as well as users especially in portable devices like cell phones and laptop computers. Power consumption also has been an issue for many industries that use computer systems heavily such as Internet service providers using servers or companies with many employees using computers and other computational devices. Many different approaches (during design of HW, SW or real-time estimation) have been discovered by researchers to estimate power consumption efficiently. This survey paper focuses on the different methods where power consumption can be estimated or measured in real-time.
Measuring real time power dissipation is critical in thermal analysis of a new design of HW like processors (CPU) just as it is important for OS programmers writing process schedulers.〔 Researchers discovered that knowing the real-time power consumption on a subsystem level like CPU, hard drives, memory and other devices can help power optimizations in applications such as storage encryption, virtualization, and application sandboxing, as well as application tradeoffs.〔(【引用サイトリンク】first=Yuwen, Lucas and Mani )〕
Different technologies have been discovered that can enable measuring power consumption in real-time. They can be ranked in two main categories: direct measurement using subsystem power sensors and meters or indirect estimation based on provided information like temperature or performance counters.〔 There are also different methods within each category; for example, different models are discovered to use performance counters for power estimation. Each one of these methods has its own benefits and disadvantages. The goal of this paper is to survey that different methods in each category.
==Run-time Estimation of System and Sub-system Level Power Consumption==
Power consumption can be different for the same type of system because of differences in manufacturing of Hardware and in temperature conditions in which the device is going to operate. Real-Time power management can be used to optimize the system or subsystems to minimize the energy consumption which may, for example, extend the battery lifetime of mobile devices or result in energy savings for Internet companies operating with many computer servers.〔 The following sections are technologies discovered to enable real-time power estimation.
