The cache control apparatus includes a coherency controller client configured to include an MESI register, which is included in an instruction cache, and stores at least one of a modified state, an exclusive state, a shared state, and an invalid state for each line of the instruction cache, and a coherency interface connected to the coherency controller and configured to transmit and receive broadcast address information, read or write information, and hit or miss information of another cache to and from the instruction cache."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cache control apparatus and method","description":"Provided is a cache control apparatus and method that, when a plurality of processors read a program from the same memory in a chip, maintain coherency of data and an instruction generated by a cache ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9824017","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.
