Task concurrency analysis and exploration of visual texture decoder on a heterogeneous platform

The emergence of mobile multimedia terminals has given rise to growing demands for power-efficient and scalable image transmission. Visual texture coding (VTC) has attracted increasing attention due to its scalability when transmitting still images. Nowadays, the implementation of such VTC decoders has not yet considered the need of energy performance trade-offs at the system-level. We have applied systematic system-level design techniques to analyze the VTC decoder and explore its timing-energy trade-off space by using our concurrent task scheduling exploration techniques. The presented approach allows a system designer to select the optimal heterogeneous platform configuration for a given speed of the VTC decoder while minimizing the global energy consumption.
