存储系统单向纠错码的比较研究
Unidirectional Error Correcting Codes for Memory Systems: A Comparative Study
摘要：
为了实现容错，高可靠系统往往需要能够在错误发生时立即检测出错误，并防止错误信息在整个系统中传播。因此，对能够检测和纠正字节错误的代码的需求是极其重要的，因为许多存储器系统使用每芯片b位的组织。为了使容错设计成为可能，必须在芯片上放置冗余。本文研究了计算机存储系统的几种方法，然后设计了一种建议的技术来选择一个合适的方法取决于存储系统的组织。所构造的代码相对于先前使用的代码需要最少数量的校验位，然后根据对数据和字节长度的要求对其进行优化以适合存储系统的组织。
英文摘要：
In order to achieve fault tolerance, highly reliable system often require the ability to detect errors as soon as they occur and prevent the speared of erroneous information throughout the system. Thus, the need for codes capable of detecting and correcting byte errors are extremely important since many memory systems use b-bit-per-chip organization. Redundancy on the chip must be put to make fault-tolerant design available. This paper examined several methods of computer memory systems, and then a proposed technique is designed to choose a suitable method depending on the organization of memory systems. The constructed codes require a minimum number of check bits with respect to codes used previously, then it is optimized to fit the organization of memory systems according to the requirements for data and byte lengths.
