Data Pointer Table Pre-Fetcher for Memory Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methodologies for identifying data pointers in memory are time-consuming, leading to power and performance losses in systems due to inefficient data retrieval and storage processes.
Innovation Solution
A system and method utilizing a data pointer table pre-fetcher that assembles a data pointer table within main memory, pre-fetches it, samples data from it, and stores it in a cache and content-addressable memory to facilitate fast lookups and efficient data transfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data pointers are identified using current methodologies, then data retrieval and storage operations can be performed, but the process takes relatively long time resulting in power and performance losses
Solution Approach 1:
The patent pre-fetches the data pointer table from main memory into a dedicated cache structure before actual data access operations are needed. This preliminary action stores frequently accessed data pointer information in a faster access medium, eliminating the time penalty of repeated main memory accesses and improving overall system productivity
Solution Approach 2:
The patent introduces a data pointer table cache as an intermediary structure between main memory and the data access operations. This intermediary holds pre-fetched data pointers, allowing rapid lookup without directly accessing main memory, thus resolving the contradiction between fast access and memory hierarchy constraints
2Loss of energy
If data pointers are identified using current methodologies, then data retrieval and storage operations can be performed, but power losses occur due to the time-consuming process
Solution Approach 1:
The data pointer table is pre-fetched and cached in advance, so that subsequent data access operations can retrieve pointers from the cache rather than performing time-consuming main memory accesses. This reduces both the time and power consumption of repeated operations
Solution Approach 2:
The system serves itself by maintaining a local cache of data pointers that can be quickly replenished from main memory when needed. The cache structure enables the system to handle common data access patterns without external intervention or repeated expensive memory operations

AI summary
A system, method, and computer program product are provided for utilizing a data pointer table pre-fetcher. In use, an assembly of a data pointer table within a main memory is identified. Additionally, the data pointer table is pre-fetched from the main memory. Further, data is sampled from the pre-fetched data pointer table. Further still, the sampled data is stored within a data pointer table cache.
