MULTI-LEVEL STARVATION WIDGET - A simplified explanation of the abstract

This abstract first appeared for US patent application 17957479 titled 'MULTI-LEVEL STARVATION WIDGET

Simplified Explanation

The disclosed method involves detecting stalled memory requests in a cache hierarchy of a processor, specifically in a first level cache with outstanding memory requests associated with a higher second level cache. The method includes notifying the second level cache of the starvation issue in the first level cache due to stalled memory requests, allowing the second level cache to take actions to address the starvation problem.

  • Detecting stalled memory requests in a first level cache within a cache hierarchy of a processor
  • Notifying the second level cache of the starvation issue in the first level cache
  • Allowing the second level cache to perform starvation-remediation actions

Potential Applications

This technology could be applied in:

  • High-performance computing systems
  • Data centers
  • Cloud computing environments

Problems Solved

This technology helps address:

  • Starvation issues in cache hierarchies
  • Performance bottlenecks in processors
  • Improving overall system efficiency

Benefits

The benefits of this technology include:

  • Enhanced system performance
  • Improved cache management
  • Better resource utilization in processors

Potential Commercial Applications

Potential commercial applications of this technology could be seen in:

  • Processor manufacturing companies
  • Data center infrastructure providers
  • Cloud computing 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 specific actions that the second level cache can take may include:

  • Prioritizing memory requests from the first level cache
  • Adjusting cache allocation policies
  • Implementing cache bypass mechanisms

How does this technology impact the overall power consumption of the processor?

This technology can potentially optimize memory access and reduce the number of stalled memory requests, leading to improved efficiency and potentially lower power consumption in the processor.


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.
