Command Queue Ordering Across Parallel Processing Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing units with multiple paths face inefficiencies due to differing capabilities and latencies, leading to potential data errors and reduced overall efficiency, as prior solutions for managing command order require significant resource consumption and complexity.
Innovation Solution
A method involving assigning commands to processing paths using identifiers that indicate receipt order, stored in a queue or buffer, allowing controllers to manage processing order efficiently with reduced resource requirements by leveraging these identifiers to ensure commands are processed in the correct sequence.

Engineering Contradiction Analysis
1Productivity
If commands are assigned to different processing paths with different capabilities and latencies, then processing efficiency is improved, but processing order may be disrupted leading to data errors
Solution Approach 1:
The system assigns sequence numbers to commands before distributing them to different processing paths. This preliminary ordering action ensures that even though commands are processed in parallel across multiple paths with different latencies, the original receipt order is preserved and can be used to reassemble results correctly.
Solution Approach 2:
The patent introduces an intermediary ordering mechanism (sequence numbers and ordering logic) that mediates between the parallel processing paths and the final result assembly. This intermediary ensures that commands are tracked and reassembled in the correct order regardless of which processing path completes them first.
2Reliability
If prior solutions are used to manage command processing order, then processing order is maintained, but resource consumption and system complexity increase significantly
Solution Approach 1:
The patent changes the approach from using complex inter-queue signaling and coordination mechanisms to a simpler parameter-based solution using sequence numbers. By attaching an ordering parameter (sequence number) to each command, the system maintains processing order without requiring complex communication infrastructure between processing queues.
Solution Approach 2:
The invention extracts the ordering information (sequence numbers) from the complex inter-queue coordination mechanism and handles ordering independently. This separation allows each processing queue to operate autonomously while the ordering logic is handled separately through the sequence number tracking mechanism.
