Burst Error Reproduction in Information Processing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission systems face challenges in reproducing and identifying the cause of burst errors, which lead to communication link failures, as these errors are often caused by external factors like noise and voltage variations, making it difficult to retransmit and correct packets effectively.
Innovation Solution
An information processing device with a receiver and processor that detects burst errors, stops data writing, and reproduces the error pattern by storing and expanding data in a memory, allowing for faithful reproduction of error packets without retransmitting them, thereby identifying the cause of link failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If burst error packets are retransmitted to reproduce the error pattern, then the cause of link failures can be identified, but external factors like noise and voltage variations make it difficult to retransmit and correct packets effectively
Solution Approach 1:
The patent creates a copy of the error packet data by storing received packets in a buffer memory before transmission. This copying approach allows the error pattern to be reproduced without retransmitting the actual physical packets, thereby avoiding the influence of external factors like noise and voltage variations that affect retransmission attempts.
2Measurement precision
If the receiving unit stores and processes all received data to reproduce error patterns, then faithful reproduction of error packets is achieved, but the complexity of the receiving unit increases
Solution Approach 1:
The patent extracts only the necessary error packet data from the received signal and stores it in a buffer memory, separating this function from the main receiving unit. This extraction approach allows faithful reproduction of error packets while keeping the receiving unit itself simple, as the storage and reproduction functions are handled by the buffer memory and control unit rather than complicating the receiving unit's structure.

AI summary
An information processing device is provided that includes a receiver to receive information from another information processing device that mutually communicates the information and a processor to process the information received by the receiver. The receiver detects occurrence of a burst error in the received information, sequentially writes the received information in a first memory, stops the writing of the information to the first memory based on detection of the burst error, shuts off transmission of the information received from the another information processing device based on a reproducing instruction, and transmits the information read from the first memory.
