A Review of Embedded Base Power Management Unit
Utsava Khare [2] | Megha Gupta [3]
Abstract: This paper Power-efficient design requires reducing power dissipation in all parts of the design and during all stages of the design process subject to constraints on the system performance and quality of service (QoS). Power-aware high-level language compilers, dynamic power management policies, memory management schemes, bus encoding techniques, and hardware design tools are needed to meet these often-conflicting design requirements. Power consumption by embedded devices is a critical issue. There is always a need to extend battery life and/or reduce the environmental impact of a system. Historically, this was purely a hardware issue, but those days are past. In modern embedded systems software takes an increasing responsibility for power management. This article reviews how power management is achieved while a device is operating and looks at the techniques employed to minimize power consumption when a device is inactive.
