Communication architecture based power management for battery efficient system design

Communication-based power management (CBPM) is a new batterydriven system-level power management methodology in which the systemlevel communication architecture regulates the execution of various system components, with the aim of improving battery efficiency, and hence, battery life. Unlike conventional power management policies (that attempt to efficiently shut down idle components), CBPM may delay the execution of selected system components even when they are active, in order to adapt the system-level current discharge profile to suit the battery's characteristics. In this paper, we present a methodology for the design of CBPM based systems, which consists of system-level performance and power profiling, battery discharge analysis, instrumentation of system components to facilitate CBPM, definition of CBPM policies, and generation of the CBPMbased system architecture. We present extensive evaluations of CBPM,
