Abstract

In this paper we propose several system-level transformations that allow to reduce the dynamic memory requirements of complex real-time multi-media systems. We demonstrate these transformations on the protocol layer of the MPEG4 IM1-player. As a consequence, up to 20% of the global power consumption of the protocol subsystem can be eliminated, which is significant due to the programmable processor target. The entire MPEG4 description is assumed to be mapped on a heterogeneous platform combining several software processors and hard-ware accelerators.
