Dual Processor Data Storage Task Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data storage devices face inefficiencies in task alignment and processing due to high overhead on the first processor and potential starvation of the second processor, as they sequentially execute tasks for multiple logical units without load-based task distribution.
Innovation Solution
Implementing a system where the first processor analyzes workloads and entrusts task alignment operations to the second processor based on workload distribution, allowing the second processor to align and execute tasks for non-high-priority logical units, thereby reducing processing overhead and preventing starvation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first processor sequentially executes task alignment operations for multiple logical units, then task alignment is completed, but processing overhead increases and the second processor experiences starvation
Solution Approach 1:
The patent segments the task alignment workload between two processors: the first processor handles task alignment for the first logical unit, while the second processor independently handles task alignment for the second logical unit. This segmentation allows parallel processing of task alignment operations, eliminating the sequential bottleneck and preventing the second processor from starving while maintaining reliable task alignment completion for all logical units.
2Measurement precision
If the first processor handles all task alignment operations, then task alignment accuracy is maintained, but the second processor remains idle causing resource underutilization
Solution Approach 1:
The patent makes both processors universal by enabling the second processor to perform task alignment operations in addition to its primary data processing function. When the second processor is idle or has completed its primary tasks, it can universally handle task alignment for the second logical unit, ensuring both processors are productively utilized while maintaining alignment accuracy through the same task alignment methodology.
3Ease of manufacture
If task alignment is performed sequentially by one processor, then processing simplicity is maintained, but overall device performance is reduced due to idle processor time
Solution Approach 1:
The patent implements preliminary action by having the second processor prepare and align tasks for the second logical unit in advance, before the first processor completes its task alignment for the first logical unit. This preliminary parallel preparation ensures that when data processing needs to occur, both processors have their tasks ready, eliminating waiting time and improving overall device performance while maintaining the simplicity of individual task alignment procedures.
