Context-Specific Marker Frame for Stack Memory Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In resource-constrained computing environments, the large amount of redundant information stored on stacks in multithreaded systems consumes valuable memory space, leading to inefficiencies and potential conflicts between applications.
Innovation Solution
Implementing a context-specific marker frame and an invocation handler to store and manage application-specific information separately from the stack, reducing redundant data storage and ensuring thread safety through context isolation and synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stacks are used to maintain information about applications running on threads in multithreaded computing systems, then thread safety and application integrity are maintained, but memory space is excessively consumed due to redundant information storage
Solution Approach 1:
The patent segments the stack information into two distinct parts: context-specific information (stored once in a context-specific marker frame) and application-specific information (stored in regular stack frames). This segmentation eliminates redundant storage of context information across multiple stack frames while maintaining thread safety through context isolation.
Solution Approach 2:
The patent extracts context-specific information from each individual stack frame and stores it separately in a context-specific marker frame. This extraction removes the redundant context information from multiple stack frames, reducing overall memory consumption while preserving the necessary thread safety mechanisms.
2Reliability
If context-specific information is stored in each stack frame to maintain application integrity, then thread safety is ensured, but the stack consumes excessive memory space in resource-constrained environments
Solution Approach 1:
The patent divides stack information into context-specific portions (stored in marker frames) and application-specific portions (stored in regular stack frames). This segmentation allows application integrity to be maintained through context markers while reducing stack memory usage by eliminating redundant context information storage in each frame.
Solution Approach 2:
The context-specific marker frame acts as an intermediary structure that stores context information separately from the main stack frames. This intermediary approach maintains application integrity by providing context information where needed while avoiding redundant storage, thus reducing overall stack memory consumption.
3Loss of information
If redundant context information is stored in multiple stack frames to track application execution, then application tracking accuracy is maintained, but memory efficiency deteriorates in resource-constrained computing environments
Solution Approach 1:
The patent segments information storage into context-specific marker frames and application-specific stack frames. This segmentation maintains application tracking accuracy by preserving context information in marker frames while reducing memory usage by eliminating redundant context data from individual stack frames.
Solution Approach 2:
Instead of copying context information into every stack frame, the patent creates a single context-specific marker frame that serves as a reference. Application-specific stack frames can access this context information without duplicating it, maintaining tracking accuracy while improving memory efficiency.

AI summary
One particular implementation may take the form of a system or method for tracking application identification and application context in a context-isolated computing environment. The method may store such application information to reduce redundant information being stored on a stack. More particularly, the embodiment may store the application information in a context-specific marker frame. The context-specific marker frame may be stored once on the stack or it may be stored separately from the stack to maintain a small stack size. In another implementation, an invocation handler method may be called to store the redundant information about the executing application. The invocation handler may store the necessary information in a well-known location for later use by the virtual machine. The invocation handler may also provide further benefits, such as synchronization to ensure thread safety on shareable objects.
