Data Pattern Based Cache Management - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240232077 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 store multiple cache lines and select which one to evict when storing a new cache line based on these patterns. It can also access data without activating internal storage arrays if the specified location contains background data.
- Cache memory circuit evicts cache lines based on stored data patterns
- Selection of cache lines for eviction is based on data patterns
- Accesses can be performed without activating internal storage arrays for background data
- Translation lookaside buffer tracks location of background data in cache memory circuit
Potential Applications: - Computer systems requiring efficient cache memory management - Systems with virtual addresses that need to track background data in cache memory
Problems Solved: - Efficient cache memory management by evicting cache lines based on data patterns - Improved performance by accessing data without activating internal storage arrays for background data
Benefits: - Enhanced cache memory efficiency - Improved system performance - Better management of background data in cache memory
Commercial Applications: Title: "Efficient Cache Memory Circuit for Enhanced System Performance" This technology can be used in various computer systems, servers, and other devices that require efficient cache memory management for improved performance. It can benefit industries such as data centers, cloud computing, and high-performance computing.
Questions about Cache Memory Circuit: 1. How does the cache memory circuit determine which cache line to evict based on data patterns? The circuit analyzes the data patterns stored in each cache line and selects the one with background data for eviction. 2. What is the role of the translation lookaside buffer in tracking background data in the cache memory circuit? The translation lookaside buffer helps identify the location of background data in the cache memory circuit, allowing for efficient management of data patterns.
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.
