The region probe filter directory identifies regions of memory for which at least one cache line may be cached in a data processing system and a state of each region, wherein a size of each region corresponds to a plurality of cache lines. The line probe filter directory identifies cache lines cached in the data processing system and a state of each cache line. The controller accesses at least one of the region probe filter directory and the line probe filter directory in response to a memory access request to determine whether to issue the probe, and does not issue any probe in response to a read-only request."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Region probe filter for distributed memory system","description":"A probe filter determines whether to issue a probe to at least one other processing node in response to a memory access request, and includes a region probe filter directory, a line probe filter direc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9792210","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.
