portable application an application that can run on dissimilar computers and/or under dissimilar operating systems. This may be done by writing it in a language which compiles for all the desired environments, or in a language which compiles to an abstract machine that is then implemented via interpreters which run on the desired environments. See Java.

The applications are recorded alongside the use of IoT idea and their advantages. Access to the mobile framework: This usage relies on the flexible headways that makes the virtual access easy for the current clinical structures. All the framework can be robotized to utilize portable application interface [6]. Examples: Websites, portable applications, etc. Virtual interview: This application depends on the quality of the network and the sound and video arrangements that help in virtual interviews, training, and treatment strategies [6]. Through this virtual interview process, most of the planned work can happen within minutes or even seconds. There is an opportunity for the development of telesurgery for systems utilizing robots and medical caretaker colleagues. Wireless patient observing: This application helps monitor basic capacities using patient gadgets [6]. Further, data is being transmitted and shared progressively among people and parental figures in the observation. This is particularly so in the case of chronic conditions like hypertension, diabetes, and so on.Aging set up: This empowers clinical monitoring for elderly people living independently. [6]. These gadgets help by checking on patients without manual intervention. The information can further be used to send help to the patients. The typical examples of this are video consultations, personal emergency responses systems (PERS), and so on. Medical devices: This application is used to track illness information and is used as health solution for patient practices, with smart devices being used to collect data from sensors for further examination by a specialist. Examples include computerized glucometers, blood-pressure devices, pedometers, wearables, and so on.

In the past, the major concern of VLSI designers were performance, area, reliability, and cost, with power being only a secondary issue. However, in recent years this has changed and power, area, and speed have become equally important. There are many reasons for this new trend. Primarily, the rapid advancement in semiconductor technology in the last decade has made possible the integration of a large number of digital CMOS circuits on a single chip. Moreover, the desirability of portable operations of these circuits has necessitated the development of low power technology. Portable applications could be anywhere from desk-tops to audio/video based multimedia products to personal digital assistants and personal communicators. These systems demand both complex functionality and low power at the same time, thereby making their design challenging. The power consumption of portable circuits has a direct bearing on the life-time of the batteries. For example, a portable multimedia terminal designed using off-the-shelf components (not optimized for low power), could consume about 30–40 watts of power. If this system were to use the state-of-the-art nickel-metal-hydride battery technology [1], it would require 4.5–6 kilograms of batteries for 10 hours of operation. Therefore, this would mean that portable systems will experience either heavy battery packs or a very short battery life. Reduction in power consumption also plays an important role for producers of non-portable systems. The state of the art microprocessors optimized for performance consume around 20–30 watts of power for operating frequencies of 150–200 MHz. With rapid advancement in technology, the speeds could reach 500–600 MHz with extraordinarily high power consumption values. This would mean that the packaging cost for such devices would be very high and expensive cooling and packaging strategies would be required. Therefore, reduction in power consumption could greatly cut cooling costs. Finally, the issue of reliability is also a major concern for consumer system designers. Systems which consume more power often run hot and acerbate failure mechanisms. In fact the failure rate increases rapidly for a small increase in operating temperature. Therefore, the maximum power consumption of the system is a crucial design factor as it could have an impact on the system cost, battery type, heat sinks, etc. Therefore, reduction in peak power is also an important issue. It is clear that the motivations for reduction in power consumption vary from application to application. In portable applications such as cellular phones and personal digital assistants, the goal is to keep the battery lifetime and weight reasonable. For high performance portable computers such as laptops, the goal is to reduce the power dissipation of the electronics portion of the system. Finally, for non-portable systems such as workstations and communication systems the goal is to reduce packaging, cooling cost and ensure long-term reliability.

Today, there are a lot of portable applications such as cellular phones, laptops, tablets, and notebooks that use image and video processors. They need lower power consumption and higher speed (Goel, Kumar, & Bayoumi, 2006; Sadeghi, Ali, & Golmakani, 2014; Shams & Bayoumi, 2000). One of the important problems facing these applications is power consumption. High power consumption will result in sooner death of the battery and increasing the charging frequency. In order to improve key metrics (i.e. power, delay and area), researchers have always designed different circuits at the transistor level. On the other hand, limited human perception has led to the use of inexact/approximate techniques to tackle this problem (Broc et al., 2015). Relaxation of precision is carried out at various levels of abstraction ranging from algorithm to transistor level (Safaei Mehrabani, Faghih Mirzaee, Zareei, & Daryabari, 2017). Image processing is tolerant against relaxation on numerical exactness (Liu, Chen, Wang, O’Neill, & Lombardi, 2016). Thus, with a slight decrease in output precision, the circuit parameters such as power consumption, delay, and transistor count can be improved.
