HDD Management Module Parallel Linked List Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hard disk drive (HDD) systems face inefficiencies when performing sort and search operations on linked lists, as these operations prevent the HDD from effectively performing other tasks, leading to sequential processing and reduced system performance.
Innovation Solution
A data management system comprising a management module that sorts and searches linked lists based on parameter sets, allowing the HDD to modify previous and next pointers of nodes, enabling parallel operation with other HDD functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If firmware of the processor performs sort and search operations on the linked list, then the linked list can be sorted and searched, but the HDD system cannot perform other operations simultaneously, reducing overall productivity
Solution Approach 1:
The patent divides the sort and search functionality into a separate dedicated management module with specialized hardware circuits, independent from the main processor firmware. This segmentation allows the management module to handle sort and search operations in parallel with the processor executing other HDD control tasks, thereby resolving the productivity loss while maintaining sort/search capability.
Solution Approach 2:
The patent introduces a dedicated management module as an intermediary between the host interface and the buffer memory. This intermediary module specifically handles sort and search operations on the linked list of data blocks, freeing the main processor from these time-consuming tasks and enabling concurrent execution of multiple HDD operations.
2Quantity of substance
If the linked list is stored in noncontiguous locations in buffer memory, then memory utilization is improved, but access time increases due to sequential access requirements
Solution Approach 1:
The patent implements a dedicated sort module that performs sorting operations on the linked list before data access operations. By preliminarily organizing the noncontiguous memory locations into an optimized sequence based on access patterns, the system reduces the time penalty associated with noncontiguous storage while maintaining high memory utilization.
Solution Approach 2:
The patent employs dynamic sorting and reordering capabilities in the management module that can adapt the linked list organization based on real-time access patterns and operation types. This dynamic reorganization optimizes access time for noncontiguous memory locations without sacrificing memory utilization efficiency.
