This access tracking flag may then be used in association with a lazy-protection program instruction (VLSTM) and a lazy-load program instruction (VLLDM) to control whether or not push operations of the state data and restore operations of the state data are performed in order to prevent access in the non-secure mode to that state data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure mode state data access tracking","description":"A data processing apparatus is provided which uses flag circuitry (174) to set an access tracking flag (SFPA) to a first value when the processing circuitry (154) enters a secure mode in association w","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10503932","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.
