一种基于RS-CRC级联的存储数据保护技术
A Storage Data Protection Technique Based on RS-CRC Concatenation
摘要
Abstract
Atmospheric radiation and other factors pose a significant threat to data in the storage systems of an avionics system.For the two common data bit widths used in aviation embedded applications,Chipkill data protection technology and data transmission paths are implemented with concatenated RS-CRC.Based on the shortened Reed-Solomon(RS)code algorithm,Chipkill data protection technology is realized,and the shortened RS encoding and decoding operations are performed in a suitable finite field selected for the application object,with a Hash lookup table decoding algorithm designed for low-latency parallel decoding.Data transmission paths hardening technology is achieved based on the cyclic redundancy check(CRC)checking mechanism and by utilizing burst transmission,without the need for additional storage resources to reinforce the write data transmission paths.Implementation and verification show that the concatenated RS-CRC design uses fewer resources,with LUT usage at only 47.5％in the finite field GF(28),and has strong error correction capabilities,making it an effective storage data protection technology.关键词
