Özet:

 

Embedded systems have geared up their applications in the field of smart   phones, mobile devices, automobiles, and medical instrumentation. Along with   the growth of technology, the functional requirements of the systems have   also grown multifold. To accommodate these ever increasing functional   requirements, the hardware should be designed to include the maximum   capability, which in turn increases power consumption. Thus this has to be   dynamically managed using software techniques. The dynamic voltage and   frequency scaling (DVFS) feature provided in most of the recent processors   has enabled power optimization through software. With this feature the   processor operating frequency can be reduced on the fly through software.   This paper proposes two approaches. In the first one, the hyper period-based   method (HPBM), the slow down factor is calculated for the hyper period and   the second method involves applying uniform slow down with frequency   inheritance (USFI) with a hyper plane exact test (HET). Both approaches aim   to calculate slow down factors for the tasks to be executed in the   processors with the DVFS feature. The main objective of this work is to   provide energy optimized scheduling as well as to minimize the overheads in   slow down factor calculations.
