Receiver Circuitry Reset Indication for Data Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data communication across different domains, existing technologies face challenges in efficiently managing message handling and reset operations, particularly in distributed systems where message transfers can be lost due to resets, leading to increased power consumption and potential data loss.
Innovation Solution
The implementation of circuitry that selectively associates an indication with control messages to identify the first control message sent after a reset, allowing the sending circuitry to track and manage outstanding messages, and using a ping mechanism to verify the receiving circuitry's operation, thereby preventing unnecessary power consumption and data loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If message sender circuitry continuously sends control messages to verify receiver operation after a reset, then reliability of message transfer is improved, but power consumption increases
Solution Approach 1:
The receiver circuitry sets a first message indicator before reset to proactively signal its operational status. This preliminary action allows the sender to know in advance that the receiver is ready to receive messages, eliminating the need for continuous verification messages and reducing power consumption while maintaining reliability
Solution Approach 2:
The first message indicator serves as feedback from the receiver to the sender, informing the sender that the receiver has recovered from reset and is ready to receive messages. This feedback mechanism enables the sender to stop sending verification messages, reducing unnecessary power consumption while maintaining message transfer reliability
2Reliability
If message sender circuitry sends verification messages after reset, then data integrity is improved, but message transfer efficiency deteriorates
Solution Approach 1:
The receiver pre-sets the first message indicator before reset occurs, so that when the sender receives this indicator after reset, it immediately knows the receiver is operational. This eliminates the need for multiple verification messages, maintaining data integrity while significantly improving message transfer efficiency
Solution Approach 2:
The first message indicator provides immediate feedback to the sender about the receiver's operational status after reset. This single feedback signal replaces multiple verification messages, ensuring data integrity through reliable status communication while improving transfer efficiency by reducing message overhead
3Loss of information
If the system tracks outstanding messages after reset, then loss of information is reduced, but device complexity increases
Solution Approach 1:
The patent extracts the status tracking function from the message content itself by using a dedicated first message indicator. This separates the operational status information from the actual message data, allowing simple tracking of receiver readiness without complex message parsing or state management, thus reducing message loss while keeping circuitry complexity low
Solution Approach 2:
The first message indicator acts as an intermediary signal between the receiver and sender, carrying operational status information without requiring complex protocols. This simple binary indicator mediates the communication after reset, preventing message loss through reliable status signaling while maintaining simplicity in the overall system design
Data Source
AI summary
Data communication apparatus comprises a receiver comprising message receiver circuitry to receive payload messages and sender control messages from message sender circuitry, the message receiver circuitry comprising: communication circuitry to send receiver control messages to the message sender circuitry, the receiver control messages relating to actions by the message receiver circuitry in response to payload messages or sender control messages from the message sender circuitry; in which the communication circuitry is configured to selectively associate a respective indication with at least some of the receiver control messages sent to the message sender circuitry, the indication indicating whether a given receiver control message with which the indication is associated is a first receiver control message sent by the communication circuitry to the message sender circuitry after a reset of circuitry in the receiver.
