Signal Transceiving Device Using Interrupt Signals for Data Size Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signal transceiving devices transmit data at a fixed size, leading to inefficient bandwidth usage and increased loading on controllers when only a portion of the data is needed by the receiving controller.
Innovation Solution
A signal transceiving device and method that uses interrupt signal wires to adjust the size of transmission data, where the second controller sends interrupt signals to the first controller to determine the necessary data size, allowing for transmission of only the required data size over a data transmission bus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If transmission data is sent with full size, then the first controller can transmit complete data, but bandwidth is wasted and controller loading increases when only part of the data is needed
Solution Approach 1:
The second controller performs preliminary action by sending interrupt signals before the actual data transmission to indicate how much data is needed. This allows the first controller to prepare and transmit only the required data size, avoiding bandwidth waste and unnecessary processing of excess data.
Solution Approach 2:
The interrupt signal mechanism establishes a feedback loop where the second controller communicates its data needs to the first controller. This feedback enables the first controller to adjust the transmission data size dynamically, improving bandwidth utilization and reducing unnecessary data transmission.
2Reliability
If transmission data is sent with full size, then data completeness is ensured, but controller loading increases non-effectively
Solution Approach 1:
The interrupt signal mechanism allows the receiving controller to preliminarily indicate its data requirements before transmission begins. This preliminary action ensures that the transmitting controller sends exactly the right amount of data to maintain reliability while avoiding the overhead of processing and transmitting unnecessary data.
3Productivity
If interrupt signal wires are added to control data size, then bandwidth usage is optimized, but device complexity increases
Solution Approach 1:
The interrupt signal mechanism segments the data transmission control into separate signal channels. By using dedicated interrupt signal wires for size indication, the system separates the control function from the data transmission function, allowing independent optimization of each while maintaining overall system efficiency.
