Mobile devices are becoming more powerful and versatile than ever, calling for better embedded processors. Following the trend in desktop CPUs, microprocessor vendors are trying to meet such needs by increasing the number of cores in mobile device SoCs. However, increasing the number does not translate proportionally into performance gain and power reduction. In the past, studies have shown that there exists little parallelism to be exploited by a multi-core processor in desktop platform applications, and many cores sit idle during runtime. In this paper, we investigate whether the same is true for current mobile applications.We analyze the behavior of a broad range of commonly used mobile applications on real devices. We measure their Thread Level Parallelism (TLP), which is the machine utilization over the non-idle runtime. Our results demonstrate that mobile applications are utilizing less than 2 cores on average, even with background applications running concurrently. We observe a diminishing return on TLP with increasing the number of cores, and low TLP even with heavy-load scenarios. These studies suggest that having many powerful cores is over-provisioning. Further analysis of TLP behavior and big-little core energy efficiency suggests that current mobile workloads can benefit from an architecture that has the flexibility to accommodate both high performance and good energy-efficiency for different application phases.

Networked Control System (NCS) is a method composed of physically shared smart devices that can observe the surroundings, work on it, and converse with one another by means of a communication system to attain a widespread purpose. Characteristic examples that fall into this section are Wireless Sensors and Actuators Networks (WSANs) for ecological analyzing and checking, multi-vehicle systems for composed investigation, camera systems for observation, multicamera facilitated movement catch, shrewd lattices for vitality circulation and the executives, and so forth. NCSs changes from increasingly customary control systems as a result of their interdisciplinary which needs the combination of control hypothesis, correspondences, software engineering and programming designing. Plenty of communication modes are available from telephone lines, cell phone networks, satellite networks and most widely used is internet. The choice of network depends upon the application to be served. Internet is the most suitable and inexpensive choice for many applications where the plant and the controller are far from each other. The troubles present in the structure of control systems that are solid to correspondence parameters like transfer speed, arbitrary deferral and packet loss, to computational parameters in light of the tremendous amount of information to be handled or to the mutual idea of the detecting and control to ongoing execution on limited resources and due to the unpredictability to the huge number of untrustworthy agent present. With the limited measure of data transmission accessible, it is improved to use it ideally and proficiently. This further raises the requirement for need choices issue for controlling a series of actuators for a progression of tasks. The proposed methodology deals broadly made in two distinct directions. The first direction aims at a control theoretical analysis while considering the network as a constant parameter like special controllers and altering the sampling rate. The second direction aims the design of new communication network infrastructures, algorithms or protocols like designing static and dynamic message scheduling algorithms. This method combines both directions and depends on the well- recognized results in both communication networks and control theory
