MULTI-LEVEL STARVATION WIDGET - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240111684 titled 'MULTI-LEVEL STARVATION WIDGET
Simplified Explanation
The disclosed method involves detecting stalled memory requests in a cache hierarchy of a processor, indicating to a higher-level cache that a lower-level cache is experiencing starvation issues, and enabling the higher-level cache to take actions to address the starvation problem.
- The method detects stalled memory requests in a first level cache within a cache hierarchy.
- The method informs a second level cache, higher in the hierarchy, about the starvation issue in the first level cache.
- The second level cache can then take actions to resolve the starvation problem, such as prioritizing certain memory requests.
Potential Applications
This technology could be applied in:
- High-performance computing systems
- Data centers
- Cloud computing environments
Problems Solved
This technology helps address issues related to:
- Cache memory starvation
- Performance bottlenecks in cache hierarchies
Benefits
The benefits of this technology include:
- Improved overall system performance
- Enhanced efficiency in memory access
- Reduction of delays in data processing
Potential Commercial Applications
The potential commercial applications of this technology include:
- Processor manufacturing companies
- Data center operators
- Cloud service providers
Possible Prior Art
One possible prior art related to this technology is the use of cache hierarchies in processors to optimize memory access and improve system performance.
What are the specific actions that the second level cache can take to address the starvation issue in the first level cache?
The second level cache can prioritize memory requests from the first level cache, allocate additional resources to the first level cache, or adjust its own caching policies to alleviate the starvation issue.
How does this technology compare to existing methods for addressing cache memory starvation in processor systems?
This technology provides a more proactive approach to addressing cache memory starvation by enabling communication between different levels of the cache hierarchy to resolve issues efficiently. Existing methods may rely on reactive measures or manual interventions to address similar problems.
Original Abstract Submitted
the disclosed method includes detecting a stalled memory request, for a first level cache within a cache hierarchy of a processor, that includes an outstanding memory request associated with a second level cache within the cache hierarchy that is higher than the first level cache. the method further includes indicating, to the second level cache, that the first level cache is experiencing a starvation issue due to stalled memory requests to enable the second level cache to perform starvation-remediation actions. various other methods, systems, and computer-readable media are also disclosed.
