Quality-aware performance analysis for multimedia MPSoC platforms

Abstract

State-of-the-art embedded devices (e.g. mobile devices) run multiple applications on multiprocessor system-on-chip (MPSoC) platforms. MPSoC platforms are becoming popular due to the increasing number and complexity of target applications. Although there is a large body of work that discusses system level performance analysis techniques for multimedia applications mapped to a MPSoC platform in various design contexts, most of these were not quality loss-aware techniques (quality losses have earlier been considered only in the case of power management). These techniques compute the platform resource requirements that enable maximum output video quality. However, multimedia applications can tolerate some data loss without significant deterioration in the output video quality. This property has not been considered in performance analysis techniques before, i.e., quality loss-aware performance analysis techniques have not been studied before. In our work, we present simulation-based and analytical performance analysis techniques to determine the system resources in a quality-aware manner. The quality resource trade-off has been shown to be important in saving vital resources for insignificant loss in quality.
