In this manner, the methods and systems are applied to achieve de-duplication of an on-chip cache. A cache line filter includes one table that defines the most commonly duplicated content patterns and a second table that saves pattern numbers from the first table and the physical address for she duplicated cache line. Since a cache line duplicate can be detected during a write operation, each write can involve table lookup and comparison. If there is a hit in the table, only the address is saved instead of the entire data string."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for memory de-duplication","description":"Provided are methods and systems for de-duplicating cache lines in physical memory by detecting cache line data patterns and building a link-list between multiple physical addresses and their common d","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9785571","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.
