A predetermined plural number of bits is taken as a data unit and the number of bits as elements constituting each vector is equal to the data unit. The operational expression includes a companion matrix of a primitive polynomial of the Galois field and defined the generation of the redundant code data strings."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Redundant code generation method and device, data restoration method and device, and raid storage device","description":"A redundant code generation method includes: dividing original data into data strings; dividing each data string into a number of bit strings that accords with an extended Galois field operation; stor","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8499224","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
