Energy Consumption In Mobile Computing

Mobile devices users have risen in recent years, by convergence of functionality and technology on it. Mobile devices also appear in market as interactive devices where users expects short-time response, usability and functionality. That convergence of digital entertainment, mobile communication technologies, and a set of new capabilities, becomes requirements for mobile application developers and hardware architects, thus both professionals have the dilemma of offer low power consumption and high performance on it. However, both concepts are opposite each other. That means, if I get a great performance, probably have attached high power consumption. Programmers have found in parallel computing, multithreading programming, and process scheduling, the way to achieve more efficiency in their programs. Moreover, hardware architects have found in multicore processors the way to achieve better performance and low-power consumption. This work wants to join both solutions and check if we can achieve less response time in applications and processes, and get a balance between performance and energy consumption.
