Abstract—This paper presents an application domain driven approach to the design of embedded systems on silicon, and it shows how this approach is used to design a chip for a multiwindow TV application. We discuss all major design steps in a logical order starting with an application domain analysis. This lead to the choice of Kahn data flow graphs as the programming paradigm for high-throughput signal applications. Based on this analysis we designed a multi-processor architecture which uses run-time reconfiguration. Finally attention is spent towards the physical implementation and the deep submicron problems we had to solve. The result is a chip that can manage up to 25 internal real-time video streams. The chip combines the flexibility of a programmable solution with the cost effectiveness of a consumer product. I
