Description

The traditional GSM phone has evolved into a complex hand-held computer system with rich stack of software including various components for interacting with web-based content. Mobile hand-helds have become versatile platforms for all kinds of use. However, connectivity remains essential for the hand-helds, but the nature of the connectivity is changing. On top of the basic communications such as cellular networks, flexible connectivity to the services found on the computational cloud is becoming essential. Our research has been covering various embedded subsystems of the hand-helds, such as application acceleration, graphics, and radiomodems. For the subsystems, high performance must often be combined with low energy consumption (i.e., long battery life), and real-time operation. We have focused especially on the cellular radio system as its performance requirements are the most demanding.
