The second-level cache and the prefetch cache are configured to allow the same cache line to be simultaneously present in both. If a request by the first-level cache for a cache line hits in both the second-level cache and in the prefetch cache, the prefetch cache invalidates its copy of the cache line and the second-level cache provides the cache line to the first-level cache."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Efficient data prefetching in the presence of load hits","description":"A memory subsystem in a microprocessor includes a first-level cache, a second-level cache, and a prefetch cache configured to speculatively prefetch cache lines from a memory external to the microproc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8543765","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.
