Analyzing Optimization Strategies and Techniques for Study of Power Management in Embedded System

Designing of Power Management requires the reduction of power dissipation in every section and unit of design system. During all these steps of designing process, it incorporates the constraints within the system and its performance. An embedded system inculcates rigid constraints to power consumption and memory of suitable size along with other terms like weight and cost. The basic Power consumption through embedded system based devices is a complex issue. The system always has to extend its battery or may reduce the environmental issues. Basically, it is a pure hardware issue. In latest development, an embedded system within its upgraded technology takes responsibility for all the power management. Embedded systems can be said to come into existence for specific purposes and should be optimized in order to meet all sorts of constraints. By constraint, it is meant to be system performance, timing, power and cost. The designing process of such system therefore involves many optimization techniques. In this paper, we will study and analyze the techniques, strategies, main advantages and disadvantages of applying optimization method of constraint problem in designing of embedded system. Also this will reviews the procedure of characterizing power management in minimizing power consumption.
