Description
Summary:Embedded real-time multimedia applications pose several challenges in order to satisfy increasing quality of service (QoS) and energy consumption constraints, that are hardly matched by the capabilities of general-purpose standard processors. Reconfigurable processors, coupling the flexibility of software-programmable devices with the computational efficiency of application specific architectures, represent an appealing trade-off for next generation devices in the digital signal processing application domain. In this paper, we present a benchmarking application for the XiRisc reconfigurable processor, based on a public release of the MPEG-2 video encoder. The introduction of the reconfigurable logic gives a 5times performance improvement and a 66% energy saving
