A Flexible and Energy-Efficient Coarse-Grained Reconfigurable Architecture for Mobile Systems


Two of the most important design issues for next generation handheld devices are wireless networking and the processing of multimedia content. Both applications rely heavily on computationally intensive digital signal processing algorithms. Programmable architectures that keep pace with the increasing performance requirements become more and more power hungry. This is problematic for a battery powered mobile device, since it has only a limited amount of energy available. Conversely, dedicated architectures are too inflexible to keep pace with changing standards and feature sets. A mobile device requires high-performance, flexibility and (energy-)efficiency. These contradicting requirements need to be balanced in the system architecture of a mobile device. In this paper a heterogeneous architecture of domain specific processing tiles is proposed. The focal point is the coarse-grained reconfigurable architecture of the Montium processing tile, which is designed to execute digital signal processing algorithms energy-efficiently.
