Accordingly, the process of reading the data into an arithmetic section is possible without having a temporary memory, and an instruction subsequent to a window switching instruction is also out-of-order executable."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Register file having multiple windows and a current window pointer","description":"In an arithmetic processing unit adopting register windows, a configuration is made such that the reading process of a register file is controlled by two stages of a current window selection and a reg","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8539208","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.
