Data Pattern Based Cache Management - A simplified explanation of the abstract
This abstract first appeared for US patent application 18360352 titled 'Data Pattern Based Cache Management
The patent application describes a cache memory circuit that evicts cache lines based on the data patterns they store, including background data patterns. The circuit can select which previously stored cache line to replace when a new cache line needs to be stored, based on the data patterns.
- The cache memory circuit can store multiple cache lines and select which one to replace based on data patterns.
- It can perform accesses without activating internal storage arrays if the specified data location is background data.
- In systems with virtual addresses, a translation lookaside buffer can track the location of background data in the cache memory circuit.
Potential Applications
This technology could be applied in various computing systems where efficient cache management is crucial, such as servers, data centers, and high-performance computing environments.
Problems Solved
This innovation addresses the challenge of optimizing cache memory usage by evicting cache lines based on data patterns, improving overall system performance and efficiency.
Benefits
- Enhanced cache memory management - Improved system performance - Efficient utilization of cache resources
Commercial Applications
Optimizing cache memory usage can lead to faster data access, improved system responsiveness, and overall better performance in various commercial applications such as cloud computing, big data analytics, and artificial intelligence.
Prior Art
There may be prior art related to cache memory management techniques, but the specific approach of evicting cache lines based on data patterns, including background data patterns, may be a novel innovation.
Frequently Updated Research
Research on cache memory optimization, data pattern analysis, and system performance enhancement may be relevant to this technology.
Questions about Cache Memory Circuit Innovation
Question 1
How does the cache memory circuit determine which cache line to replace based on data patterns?
Answer
The cache memory circuit analyzes the data patterns stored in each cache line and selects the one with background data patterns for eviction when a new cache line needs to be stored.
Question 2
What are the potential implications of using a translation lookaside buffer in systems with virtual addresses?
Answer
The translation lookaside buffer helps track the location of background data in the cache memory circuit, improving the efficiency of cache management in systems with virtual addresses.
Original Abstract Submitted
A cache memory circuit that evicts cache lines based on which cache lines are storing background data patterns is disclosed. The cache memory circuit can store multiple cache lines and, in response to receiving a request to store a new cache line, can select a particular one of previously stored cache lines. The selection may be performed based on data patterns included in the previously stored cache lines. The cache memory circuit can also perform accesses where the internal storage arrays are not activated in response to determining data in the location specified by the requested address is background data. In systems employing virtual addresses, a translation lookaside buffer can track the location of background data in the cache memory circuit.
