Developing a framework for Power Management Validation on Windows 8 OS

Abstract

Today, the complexity of computing platforms has increased with the development of SoC' s coupled with dozens of platform component and support for multiple Oper- ating systems. Validation of SoC and platform component is immensely complicated. One of the most important features of a Platform is Power Management and Per- formance of system. Power management aims at reducing operating costs for energy and cooling systems while at the same time keeping the performance of a system at a level that matches the current requirements. Thus, power management is always a matter of balancing the actual performance needs and power saving options for a system. Power management can be implemented and used at di erent levels of the system. A set of speci cations for power management functions of devices and the operating system interface to them has been de ned in the Advanced Con guration and Power Interface. As power savings in tablet platform can primarily be achieved on processor level, system level, platform level .The aim of this project to develop a tool which is use to measure attributes contributing to Power and Performance on SoC and other peripheral devices on 32nm based SoC Tablet Platform with support- ing Windows 8 Operating System. The features supported by this tool are C-state Residency, P-State Residency, and S-State Residency etc.
