Cross-OS Memory Sharing via Dynamic Buffer Address Mapping

The patent introduces a memory management unit (MMU) as an intermediary component that facilitates memory sharing between different operating systems. The MMU manages memory allocation, address translation, and access control, allowing efficient data transmission while isolating the complexity of memory management from the individual operating systems. This mediator approach resolves the contradiction by centralizing complex operations in a dedicated component.

The patent segments memory into distinct regions with different access permissions and characteristics. By dividing memory into shared regions, private regions, and protected regions, the system enables efficient data transmission in shared areas while maintaining security and isolation through segmentation. This reduces overall system complexity by organizing memory management into manageable segments rather than requiring complex global coordination.

The patent applies local quality by assigning different memory access permissions and protection levels to different regions of the same memory space. Each operating system can access specific memory regions with appropriate permissions, allowing high resource utilization while preventing interference through localized access control. Critical system areas have restricted access, while shared data areas have appropriate read/write permissions.

The patent implements beforehand cushioning through protective mechanisms that prevent memory interference before it occurs. Memory protection bits, access control lists, and validation checks are established in advance to block potential interference from unauthorized access attempts. This proactive approach allows multiple operating systems to share the integrated circuit safely without actual interference occurring.
