Signal Processor Transaction Buffer Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Signal processors face reduced efficiency due to the need for interrupting processes to ensure coherent data transfer from a central processing unit, which disrupts ongoing operations and reduces data transfer velocity.
Innovation Solution
Incorporating a transaction buffer that allows data transfer between the signal processor and processing memory at a selectable instant, decoupling data reception from the signal processor's internal processes, enabling continuous operation without interrupting process routines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transfer is performed directly between the central processing unit and the signal processor, then data coherence is ensured, but the signal processor must interrupt its processes, reducing efficiency
Solution Approach 1:
A transaction buffer is introduced as an intermediary component between the central processing unit and the signal processor. The buffer receives data packets from the central processing unit and transfers them to the signal processor's processing memory, eliminating the need for the signal processor to interrupt its processes while ensuring complete and coherent data transfer.
Solution Approach 2:
Data packets are transferred to the transaction buffer in advance before the signal processor needs them. The buffer holds the data ready for transfer, allowing the signal processor to continue its processes without interruption while the data is staged for coherent transfer at the appropriate time.
2Reliability
If the signal processor interrupts processes for data transfer, then complete data transfer is achieved, but data transfer velocity is reduced
Solution Approach 1:
The transaction buffer acts as a mediator that handles the complete data transfer independently. Data packets are transferred to the buffer and then to the processing memory without requiring signal processor intervention, maintaining both completeness and high velocity through asynchronous operation.
Solution Approach 2:
The signal processor continues its processes continuously without interruption while the transaction buffer handles data transfer in the background. This ensures both complete data transfer and maintains high data transfer velocity by eliminating pauses in processor operation.
3Reliability
If data transfer is synchronized with process routines, then data coherence is maintained, but process efficiency is reduced due to frequent interruptions
Solution Approach 1:
The transaction buffer decouples data transfer from process routines by serving as an independent intermediary. Data packets are transferred to and from the buffer asynchronously, allowing process routines to execute continuously without synchronization interruptions while the buffer manages data coherence independently.
Solution Approach 2:
The data transfer function is segmented from the process routine execution. The transaction buffer handles data reception and transfer as a separate, independent function, allowing the signal processor to focus on process execution without being interrupted by data transfer synchronization requirements.
