本文介绍了在硅片上设计嵌入式系统的应用领域驱动方法，并介绍了如何利用这种方法设计多窗口电视应用芯片。我们从应用领域分析开始，按逻辑顺序讨论了所有主要设计步骤。这促使我们选择 Kahn 数据流图作为高吞吐量信号应用的编程范例。在这一分析的基础上，我们设计了一种使用运行时重新配置的多处理器架构。最后，我们还关注了物理实现和我们必须解决的深亚微米问题。最终，这款芯片可以管理多达 25 个内部实时视频流。该芯片兼具可编程解决方案的灵活性和消费产品的成本效益。
This paper presents an application domain driven approach to the design of embedded systems on silicon, and it shea 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 multiprocessor architecture which uses run-time reconfiguration. Finally, attention is spent toward 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.
