The suppressing may include generating a known-to-hit signal where the next fetch is in the same cache line, and the last fetch is not a branch instruction, and issuing an instruction cache hit where a cache line segment of the same cache line having the next instruction has a valid validity bit, the valid validity bit having been retrieved and maintained based on a most-recent, instruction cache-directory-accessed fetch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Selective suppression of instruction cache-related directory access","description":"Processing of an instruction fetch from an instruction cache is provided, which includes: determining whether the next instruction fetch is in a same cache line of the instruction cache as a last inst","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9851974","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.
