Cache Line Address Cross-Referencing with Symbolic Names
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cache monitoring techniques are inadequate for effectively visualizing and debugging software applications, as they fail to provide comprehensive information about cache contents and states, making it difficult to identify issues during software development.
Innovation Solution
A system and method that collect information from multiple cache levels, associate cache line addresses with corresponding names, and display this information on a graphical user interface (GUI) to facilitate visualization and debugging, allowing for cross-referencing of cache line addresses with their names and providing detailed insights into cache states and contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If comprehensive cache information is collected and displayed, then debugging capability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a cache monitoring module as an intermediary component that collects cache information from multiple cache levels and presents it through a graphical user interface. This mediator handles the complexity of data collection and processing internally, while providing a simplified view to users, thus improving monitoring capability without proportionally increasing user-facing system complexity.
Solution Approach 2:
The system creates a virtual representation or copy of cache contents and states through the graphical user interface, allowing developers to view and analyze cache information without directly accessing or modifying the actual cache hardware. This copying approach enables comprehensive monitoring while maintaining a clear separation between the monitoring system and the cache subsystem.
2Loss of information
If detailed cache contents and states are visualized, then software debugging is improved, but information processing time increases
Solution Approach 1:
The system implements selective caching of cache information, where only relevant or recently accessed cache data is retained and displayed in detail, while less critical information is summarized or omitted. This partial action approach provides sufficient debugging information without processing and displaying every possible cache detail, thus reducing processing time while maintaining information completeness for debugging purposes.
3Ease of operation
If cache information is displayed without cross-referencing, then display simplicity is maintained, but debugging efficiency decreases
Solution Approach 1:
The patent adds a cross-referencing dimension to the cache display by associating cache line addresses with symbolic names or descriptors. This additional dimension allows developers to correlate numerical addresses with meaningful identifiers, improving debugging efficiency without significantly complicating the display through hierarchical or multi-layered interfaces.
Data Source
AI summary
An information carrier medium containing software that, when executed by a processor, causes the processor to receive information from caches on different cache levels. The caches comprise a plurality of cache line addresses, each cache line address associated with a corresponding name. The software causes the processor to display the information on a graphical user interface (GUI), the GUI cross-referencing each of the cache line addresses with a corresponding name.
