Abstract

Presents experiences from modelling real-time applications in the declarative functional language H, developed hand-in-hand with a novel parallel graph reduction architecture called rp8601, both designed with the requirements of real-time embedded systems in mind. In rp8601, the analogue and digital interactions with the environment have been designed into the chips and into the language, and so have mechanisms to handle time constraints. Traditionally, declarative programming means that the programmer need not be aware of the processor operations. Instead, he can focus on the abstract relations between the input and output streams. The specific real-time requirements have normally not been taken into account in the declarative view. Our conclusion is that declarative functional programming is a viable technique for the development of complex software for embedded real-time systems. However, considerable efforts have to be spent on educating and training the application programmers in the new programming paradigm.<>

声明式编程与并行执行在计算机实时系统中的应用

介绍了在声明式函数语言H中建模实时应用程序的经验，该语言与一种名为rp8601的新型并行图简化体系结构携手开发，两者都是根据实时嵌入式系统的需求设计的。在rp8601中，与环境的模拟和数字交互已被设计到芯片和语言中，因此具有处理时间限制的机制。传统上，声明式编程意味着程序员不需要知道处理器的操作。相反，他可以专注于输入和输出流之间的抽象关系。在声明性视图中，通常没有考虑到具体的实时需求。我们的结论是，声明式函数式编程是开发嵌入式实时系统复杂软件的可行技术。然而，在新的编程范式中，必须花费相当大的努力来教育和培训应用程序程序员。
