Abstract

Abstract This article discusses computing systems that operate in residue number systems (RNSs). The main direction of improving computer systems (CSs) is increasing the speed of implementation of arithmetic operations and the reliability of their functioning. Encoding data in RNS solves the problem of optimal redundancy, i.e., the creation of such computing systems provides maximum reliability with restrictions on weight and size characteristics. This article proposes new structures of fault-tolerant CSs operating in RNS in the case of the application with an active fault-tolerant method. The use of the active fault-tolerant method (dynamic redundancy) in the RNSs provides higher reliability. In addition, with an increase in the digits of CSs, the efficiency of using the proposed structures increases.

基于剩余数系统的容错计算机系统结构设计

摘要本文讨论了在残数系统中运行的计算系统。改进计算机系统的主要方向是提高算术运算的执行速度及其功能的可靠性。RNS中的数据编码解决了最佳冗余问题，即，创建这样的计算系统在重量和尺寸特性受到限制的情况下提供了最大的可靠性。本文在应用主动容错方法的情况下，提出了在RNS中运行的容错CS的新结构。在RNS中使用主动容错方法（动态冗余）提供了更高的可靠性。此外，随着CS位数的增加，使用所提出的结构的效率也提高了。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
