Abstract

The thesis described a general codesign methodology for specialized processors. The different design tools were described and the configuration of these tools into complex design flows was explained. This section will present the results for a specific application spectrum: video compression. It is defined by the programs of Table 2.3 in section 2.1. The complexity of these applications reflects the characteristic challenges of designing high-performance video processing systems. The results are typical for the requirements imposed by video processing: a demand of high processing power and large memory bandwidth. But at the same time, the results also reflect special decisions and implementation constraints for the particular embedded system design. This means, they cannot be transferred completely to another design of an embedded video compression system. All these designs differ from each other. Exploiting these different constraints is one of the strong points of design automation for embedded systems. This makes it possible to tailor even a complex system to very specific constraints. It improves the overall performance / cost ratio of the system in comparison to more general solutions. Therefore the tools for measuring the results and the measurement strategy are more important than the specific values of the analysis results.
