Abstract

Modern multimedia applications are becoming increasingly dynamic. The state-of-the-art scalable 3D graphics algorithms are able to adapt at run-time their hardware resource allocation requests according to input, resource availability and a number of quality metrics. Additionally, the resource management mechanisms are becoming more dynamic themselves and are able to cope efficiently at run-time with these varying resource requests, available hardware resources and competing requests from other applications. In this paper, we study the dynamic resource requests of the Wavelet Subdivision Surfaces (WSS) based scalable 3D graphics application. We also show how to schedule its computational resources at run-time with the use of the Task Concurrency Management (TCM) methodology and the System Scenario based approach on MPSoC platform with very heterogeneous Processing Elements (including RISC, VLIW and FPGA accelerator resources).
