“…We experimented with a systems-architecture that accommodated the required functionality, within the energy limitation constrains of a small battery-powered device. This systems-architecture has some similarities with the Desk Area Network in Cambridge [5] and the Pleiades project in Berkeley [1] [2].…”

Abstract. This paper discusses reconfigurability issues in low-power 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.

“…1(a) illustrates the architecture with its separate control and data interconnects. Such "coarse-grain" reconfigurable architectures have been proposed before [2]. However, with modern FPGAs providing embedded arithmetic slices optimized for DSP operations, the DRUID system can be implemented in an FPGA.…”

The Strathprints institutional repository (https://strathprints.strath.ac.uk) is a digital archive of University of Strathclyde research outputs. It has been developed to disseminate open access research outputs, expose data about those outputs, and enable the management and persistent access to Strathclyde's intellectual output. Real-time signal processing in plasma fusion experiments is required for control and for data reduction as plasma pulse times grow longer. The development time and cost for these high-rate, multichannel signal processing systems can be significant. This paper proposes a new digital signal processing (DSP) platform for the data acquisition system that will allow users to easily customize real-time signal processing systems to meet their individual requirements. The D-TACQ reconfigurable user in-line DSP (DRUID) system carries out the signal processing tasks in hardware co-processors (CPs) implemented in an FPGA, with an embedded microprocessor ( P) for control. In the fully developed platform, users will be able to choose co-processors from a library and configure programmable parameters through the P to meet their requirements.The DRUID system is implemented on a Spartan 6 FPGA, on the new rear transition module (RTM-T), a field upgrade to existing D-TACQ digitizers.As proof of concept, a multiply-accumulate (MAC) co-processor has been developed, which can be configured as a digital chopper-integrator for long pulse magnetic fusion devices. The DRUID platform allows users to set options for the integrator, such as the number of masking samples. Results from the digital integrator are presented for a data acquisition system with 96 channels simultaneously acquiring data at 500 kSamples/s per channel.

“…The wireless network interface of a mobile computer consumes a significant fraction of the total power [11]. It is not sufficient to minimize the energy consumption during transmission and reception of data only, since measurements show that on typical applications like a web-browser or e-mail, the energy consumed when the interface is on and idle is more than the cost of tsansceiving packets.…”
