Mobile SoCs, Power Optimization, Battery Life, Dynamic Voltage, Frequency Scaling (DVFS)Abstract
Mobile SoCs or System-on-Chip have been the backbone of any modern smartphone, whether for communications or gaming. As the need for optimal performance and energy efficiency of mobile electronics rises, it has become crucial for mobile SoC design. Battery is another important factor, and more to the point, the use of mobile devices strongly depends on battery life. The power control techniques that will enable efficient power utilization in present-day mobile SoCs are also presented in this paper. Our current work addresses DVFS, clock gating, power gating, load balancing, and power-efficient design styles. Furthermore, we also explore such aspects as hardware and software methods, low-power communication protocols, and advanced semiconductor solutions. The methods are assessed relative to their capability to achieve the desired goal, which is to decrease power use while at the same time not leading to impaired performance of portable devices. Moreover, we include examples of the actual use of any of the mentioned strategies and illustrate battery life improvement in different SoC designs.
