PREFETCH AWARE LRU CACHE REPLACEMENT POLICY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240104025 titled 'PREFETCH AWARE LRU CACHE REPLACEMENT POLICY
Simplified Explanation
The abstract describes a prefetch-aware LRU cache replacement policy implemented in a graphics processor's load store cache.
- The apparatus includes one or more processors, including a graphic processor with a load store cache.
- The cache has multiple cache lines (cls), each with a cache line level (cl level) and one or more sectors for data storage.
- The graphics processor receives data elements for storage in the cache and sets a cl level to track each cls receiving data.
- Cl level 1 is set for a cls receiving data in response to a cache miss, while cl level 2 is set for a cls receiving prefetched data in response to a prefetch request.
- When space is needed in the cache, a cache replacement policy is applied based on set cl levels for the cls.
Potential Applications
This technology can be applied in various systems requiring efficient cache management, such as high-performance computing, gaming consoles, and graphic-intensive applications.
Problems Solved
1. Efficient cache utilization: By implementing a prefetch-aware LRU cache replacement policy, the system can optimize cache space and improve overall performance. 2.

Original Abstract Submitted
prefetch aware lru cache replacement policy is described. an example of an apparatus includes one or more processors including a graphic processor, the graphics processor including a load store cache having multiple cache lines (cls), each including bits for a cache line level (cl level) and one or more sectors for data storage; wherein the graphics processor is to receive one or more data elements for storage in the cache; set a cl level to track each cl receiving data, including setting cl level 1 for a cl receiving data in response to a miss in the cache and setting a cl level 2 for a cl receiving prefetched data in response to a prefetch request, and, upon determining that space is required in the cache to store data, apply a cache replacement policy, the policy being based at least in part on set cl levels for the cls.
