A New Platform For Multimedia Applications
The convergence between broadcast systems and new digital services driven by common multimedia applications generates new requirements for the DSP platforms: they must be highly optimized to provide implementations of very complex algorithms at minimum power consumption, but also have to be as open and as reusable as possible. The existing sub-micron technology makes an integration of very complex architectures technically feasible and economically reasonable and shifts the challenges of research and development from feasibility questions to the questions of software partitioning and programmability. Modularity, interoperability, and reusability become the crucial requirements for new DSP platforms. In this article a DSP platform applicable in a variety of multimedia products is presented. Based on modern algorithms for video and audio compression and an evaluation of existing platforms, a multiprocessor architecture including specialized coprocessor units, called streaming units, for critical performance bottlenecks in audio and video compression as well as the necessary tools are presented.
