The system is configured to allocate an amount of physical memory in the main storage and the IOMMU is configured to provide access to the main storage and to map a PCI address from the PCI device to a physical memory address within the main storage. The mapper is configured to perform a mapping between the allocated amount of physical memory of the main storage and a contiguous PCI address space. The IOMMU is further configured to translate PCI addresses of the contiguous PCI address space to the physical memory address within the main storage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mapping device addresses to physical memory addresses","description":"A data processing system includes a main storage, an input/output memory management unit (IOMMU) coupled to the main storage, a peripheral component interconnect (PCI) device coupled to the IOMMU, and","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9785597","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.
