越来越重要的是，构造信号处理算法和系统，以允许在其实现中在结果的准确性和资源的利用之间进行权衡。在任何特定的情况下，通常有各种启发式方法来管理这些权衡。本文的目标之一是建议，有可能开发一个更正式的方法，包括利用目前的研究在计算机科学的近似处理和它的中心概念之一，增量细化。为此，我们首先总结了一些想法和方法，目前正在制定的计算机科学界的近似处理。然后，我们提出了四个例子的信号处理算法/系统，结构与这些目标铭记。这些示例可以被视为朝着在信号处理设计和实现的背景下开发用于利用和扩展近似处理概念和方法的更一般和严格的框架的最终目标的部分进展。
It is increasingly important to structure signal processing algorithms and systems to allow for trading off between the accuracy of results and the utilization of resources in their implementation. In any particular context, there are typically a variety of heuristic approaches to managing these tradeoffs. One of the objectives of this paper is to suggest that there is the potential for developing a more formal approach, including utilizing current research in Computer Science on Approximate Processing and one of its central concepts, Incremental Refinement. Toward this end, we first summarize a number of ideas and approaches to approximate processing as currently being formulated in the computer science community. We then present four examples of signal processing algorithms/systems that are structured with these goals in mind. These examples may be viewed as partial inroads toward the ultimate objective of developing, within the context of signal processing design and implementation, a more general and rigorous framework for utilizing and expanding upon approximate processing concepts and methodologies.
