Recently, Android is being integrated and applied to various embedded systems because of good characteristics like open source, a wide connective range, multitasking, and secure communications. Most of the modern embedded designers have been focused on system performance while reducing operating power consumption. However, increasing the performance level inevitably increases power consumption. In this article, an optimal power management (OPM) system is proposed for embedded systems using a novel scheduling algorithm. It can control the operating power consumption of open source platforms (Raspberry-PI, Parallella, and Arduino) supported hardware devices (ZynqBerry, ZynqParallela, and ArduZynq). The proposed OPM system uses the scheduling algorithm based on the functionality of optimization and their tasks. Moreover, the proposed OPM system provides the low or high frequency to the devices upon receiving the low frequency and high frequency request from the devices. The simulation result is calculated in terms power consumption, maximum operating frequency and hardware utilization.

1. Introduction

An embedded system is a picking structure joined with a more essential structure organized submitted limits (Papp, Ma, & Buttyan, 2015). It can in like manner be portrayed as an astonishing kind of PC system that plays out some specific pre-delineated endeavors which is everything seen as used inside a more perceptible size of electrical or mechanical structure. Nowadays exhibited structures are used in each piece of our lives from specific satisfaction to human affiliations and social event. In spite of where used, about in any case the issue with the power use is a victor among the most overpowering errands to be lit up (Li & Mishra, 2016). Power consumption follows the low transmission ask correspondence, or even be sans battery when empowered by including power (Gay et al., 2014). Looking over the legitimate objective to diminish the power usage of the sensors, the short or low major powers should be given to the contraptions (Gay et al., 2014). Asking for of low centrality introduced structures are making and reducing. Essentialness utilize is a victor among the most pivotal game-plan criteria for battery-controlled contraptions and structures. Dynamic power management and dynamic voltage and frequency scaling (DVFS) systems have been absolutely dejected down for lessening criticalness utilization of battery filled structures while meeting execution targets. Centrality gathering strategy (Hartgenbusch et al., 2017) has been passed on to beat the inspiration driving low power of essentialness source and progression the destiny of un-annexed introduced structures (Shafik et al., 2015).

Processor control use is made out of static and dynamic power. Since change scaling results in the exponential increments of static power, it ends up principal stress for the future CMOS progress. In addition, an immense measure of dynamic power is scattered in the select record as a result of the high change. In like manner, organizers should facilitate both static also unprecedented power in the processor to reduce centrality use and beginning now and into the not so distant improve battery life (Lin et al., 2016). With the change of gear contraptions and correspondence advancement, demonstrated devices have starting at now get into various space, for instance, life, industry, national demand, helpful treatment et cetera. Remote, vehicle-mounted structure, switch, shocking home, et cetera are persisting demonstrated contraptions. The progression of Internet of Things makes the use of showed contraptions essentially wider and more crucial mechanical get-together interfaces into coordinate. So, the security issues of exhibited structure get dependably thought (Tavana, Khameneh, & Goudarzi, 2015). These security threats have changed into a principal issue at show up in light of the course that by a wide edge by far a substantial segment of the demonstrated structures require security in a general sense more than PCs. One elucidation for this nonappearance of security is the particular obliged hardware and programming use decisions for the makers of embedded structure affiliations (Hou, Li, & Chang, 2017).The deferral appeared by the structure essentially impacts the system execution can be overseen by different Quality of Service (QoS) levels (Anik, MinhazulHoque, & Akter) Modelers of joined circuits turn resuscitating the likelihood of their things reviewing a complete objective to diminish their ability utilize, which results in a more extended battery length (Franchino & Buttazzo, 2017, Negi, Mishra, & Gupta, 2013).
