Solution Overview
Problem
Existing communication pathways between complex digital systems are vulnerable to performance degradation due to throughput constraints, leading to increased delays and decreased performance.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication is performed via a communication bridge between operating systems, then communication can be established, but bandwidth constraints and throughput limitations occur
Solution Approach 1:
The patent introduces shared memory as an intermediary communication mechanism between the virtualized operating system and host operating system. Instead of using the traditional communication bridge interface, data is transmitted through a shared memory region that both operating systems can directly access, thereby eliminating the bandwidth constraints of the communication bridge while maintaining reliable communication.
Solution Approach 2:
The patent extracts the communication data transmission function from the constrained communication bridge interface and relocates it to shared memory. By separating the communication capability from the limited interface, the system achieves high-speed data transfer while the communication bridge remains available for control and management functions.
2Device complexity
If traditional communication interfaces are used between virtualized systems, then system architecture is maintained, but transmission speed is limited
Solution Approach 1:
The patent transitions communication from a one-dimensional interface-based approach to a multi-dimensional approach by introducing shared memory space. This allows simultaneous access from multiple operating systems without sequential processing through a communication bridge, dramatically increasing transmission speed while preserving the virtualization architecture.
3Reliability
If communication bridge interface is used, then operating systems can communicate, but delays increase due to throughput constraints
Solution Approach 1:
The patent enables continuous data transmission between operating systems through shared memory without the intermittent processing delays inherent in communication bridge interfaces. The shared memory allows both operating systems to read and write data simultaneously and continuously, eliminating the queuing and processing delays that occur with traditional interface-based communication.
