CACHING TECHNIQUES USING A MAPPING CACHE AND MAINTAINING CACHE COHERENCY USING PHYSICAL TO LOGICAL ADDRESS MAPPING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240303199 titled 'CACHING TECHNIQUES USING A MAPPING CACHE AND MAINTAINING CACHE COHERENCY USING PHYSICAL TO LOGICAL ADDRESS MAPPING
Simplified Explanation: The patent application describes caching techniques for improving read operations by efficiently storing and accessing data mappings.
Key Features and Innovation:
- Utilizes two hash tables in the mapping cache for efficient storage and retrieval of data mappings.
- Implements read hit mapping cache processing to quickly access content stored at a logical address.
- Introduces read miss mapping cache processing to add missing data mappings to the cache for future access.
Potential Applications: This technology can be applied in various systems that require fast and efficient data access, such as databases, file systems, and network storage solutions.
Problems Solved:
- Improves read performance by reducing the time taken to access data mappings.
- Enhances overall system efficiency by optimizing the caching process for read operations.
Benefits:
- Faster read operations leading to improved system performance.
- Reduced latency in accessing data mappings for enhanced user experience.
- Efficient utilization of cache memory for better resource management.
Commercial Applications: The technology can be utilized in cloud storage services, content delivery networks, and data-intensive applications to enhance data access speed and system responsiveness.
Prior Art: Further research can be conducted in the field of caching techniques, specifically focusing on optimizing read operations through advanced data mapping strategies.
Frequently Updated Research: Stay updated on advancements in caching technologies and data storage optimization to leverage the latest innovations in improving system performance.
Questions about Caching Techniques: 1. How do caching techniques impact overall system performance? 2. What are the key differences between read hit and read miss mapping cache processing?
Original Abstract Submitted
caching techniques can include: receiving a read i/o operation requesting to read from a logical address; determining whether a mapping cache includes a descriptor for the logical address, the mapping cache including two hash tables; responsive to determining that the mapping cache includes the descriptor for the logical address, performing read hit mapping cache processing which includes using a physical location identified by the descriptor to read content stored at the logical address; and responsive to determining that the mapping cache does not include the descriptor for the logical address, performing read miss mapping cache processing which includes adding the descriptor to the mapping cache. read miss mapping cache processing can include adding the descriptor to a first hash table, used to access the descriptor by the logical address, and adding the descriptor to a second hash table used to access the descriptor by the physical location.
