Virtual Machine Host Memory Communication Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The communication process between a host and a Universal Flash Storage (UFS) device is complex and cumbersome, involving multiple layers such as the interconnect layer, transport layer, and application layer, which increases complexity and reduces operation speed.
Innovation Solution
A computer-executed method is provided where a first virtual machine, configured to emulate a host, sends a request to a second virtual machine, configured to emulate a memory system, to establish communication. This method simplifies the communication process by eliminating the need for the interconnect, transport, and application layers, allowing direct communication between the host and memory system emulated by the virtual machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication process between host and UFS device follows the traditional multi-layer protocol (interconnect layer, transport layer, application layer), then the communication is standardized and reliable, but the process becomes complex and time-consuming
Solution Approach 1:
The patent extracts and removes the intermediate protocol layers (interconnect layer, transport layer, application layer) from the communication path between host and UFS device. By directly establishing a communication link between the two endpoints, it eliminates the complexity and time delays introduced by multiple intermediary layers while maintaining communication reliability through direct peer-to-peer interaction.
Solution Approach 2:
Instead of following the traditional bottom-up approach where communication must pass through lower-level protocol layers first, the patent inverts the communication model by allowing direct high-level interaction between host and device. This inversion bypasses the conventional hierarchical structure, enabling simplified direct communication while still ensuring data integrity and reliability.
2Reliability
If the communication process includes multiple protocol layers (interconnect, transport, application), then protocol compliance is ensured, but communication time increases and speed decreases
Solution Approach 1:
The patent extracts the essential communication functionality from the multi-layer protocol stack, retaining only the critical error-checking and data transfer mechanisms while removing the time-consuming intermediate layers. This extraction maintains sufficient protocol compliance for reliable communication while dramatically reducing the time required for data exchange between host and UFS device.
3Productivity
If virtual machines are used to emulate host and memory system, then communication can be simplified and speed increased, but system configuration complexity increases
Solution Approach 1:
The patent creates virtual machine copies of the host and memory system that replicate the essential communication interfaces and protocols. These virtual instances provide a simplified communication environment that mimics real hardware behavior, enabling faster communication while the virtualization layer abstracts away the underlying complexity of direct hardware configuration.
