Reconfigurable Mobile Multimedia Systems
This paper discusses reconfigurability issues in lowpower hand-held multimedia systems, with particular emphasis on energy conservation. We claim that a radical new approach has to be taken in order to fulfill the requirements - in terms of processing power and energy consumption - of future mobile applications. A reconfigurable systems-architecture in combination with a QoS driven operating system is introduced that can deal with the inherent dynamics of a mobile system. We present the preliminary results of studies we have done on reconfiguration in hand-held mobile computers: by having reconfigurable media streams, by using reconfigurable processing modules and by migrating functions
Exploring Energy-Efficient Reconfigurable Architectures for DSP Algorithms
Future hand-held multimedia terminals require a very high performance on a very small energy budged. Such devices can only be realized if their entire system is energy cognisant. In this paper a reconfigurable systems-architecture for mobile multimedia systems is introduced. The Field Programmable Function Array (FPFA) is discussed in detail. Several digital signal processing algorithms are discussed and mapped on the FPFA. Also,the power radius theory about low-power design is introduced
