Each second filter is generated with a size at least partially accommodated within the storage capacity of the associated memory. The system determines absence of items from a set by selectively probing the generated filters in an ascending order of data access speed to the associated memories and aborts further probing for an item in response to a probe indicating that the item is absent from the set. Embodiments of the present invention further include a method and computer program product for testing set membership in substantially the same manners described above."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multilevel filters for cache-efficient access","description":"According to one embodiment of the present invention, a system with a plurality of memories, generates a first filter associated with a first memory, and generates one or more second filters each asso","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9740714","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.
