Processor Health-Check System for Cache Memory Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CPU systems face downtime and performance degradation due to cache memory errors, which often require physical replacement of cache memory or entire CPU modules, especially when multiple CPUs are used, as identifying unhealthy CPUs before failure is challenging.
Innovation Solution
A method for evaluating CPU health by initializing and executing an operating system, de-allocating the CPU from system resources, performing a health-check, and potentially repairing cache elements by swapping in spare components while the system is running, allowing for proactive maintenance and minimizing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical removal and replacement of cache memory is performed, then reliability is improved, but loss of time increases
Solution Approach 1:
The system performs health checks on cache memory periodically to identify failing cache elements before they cause system failures. By detecting cache errors early through monitoring operations, the system can schedule replacements during maintenance windows rather than responding to failures after they occur, thus reducing unexpected downtime while maintaining reliability
Solution Approach 2:
The system includes self-diagnostic capabilities through health check routines that automatically monitor cache memory status. The operating system can identify failing cache elements and initiate replacement procedures without requiring manual intervention, enabling proactive maintenance that minimizes system downtime while ensuring reliability
2Reliability
If physical removal and replacement of CPU module is performed, then reliability is improved, but device complexity increases
Solution Approach 1:
The invention segments the CPU module into separable components, specifically identifying cache memory as a replaceable element independent from the main CPU chip. This allows replacement of only the failing cache memory module rather than the entire CPU, reducing replacement complexity while maintaining system reliability
Solution Approach 2:
The patent extracts the cache memory as a separate replaceable component from the CPU module. By taking out the cache memory as an independent serviceable element, the system enables targeted replacement of failing cache elements without requiring replacement of the entire CPU module, thus reducing device complexity and maintenance burden
3Measurement precision
If health-check is performed on de-allocated CPU, then measurement precision is improved, but productivity decreases
Solution Approach 1:
The system performs health checks periodically at scheduled intervals rather than continuously. By using periodic health-check routines that execute at predetermined times, the system maintains measurement precision for detecting CPU health status while minimizing the impact on overall system productivity through controlled, intermittent monitoring
Solution Approach 2:
The system de-allocates CPU resources in advance for health-check operations, preparing the CPU for diagnostic procedures before actual monitoring begins. This preliminary preparation ensures measurement precision by ensuring the CPU is ready for accurate health assessment while managing productivity through planned resource allocation
