Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data transmission systems face increased error occurrences due to crosstalk between semiconductor device components as operation speeds increase, particularly in electronic devices, where data transmitted through one line can be affected by electromagnetic energy from adjacent lines.
Innovation Solution
A data transmission system and method that includes a data transmitter and receiver configured to transmit 'N'-bit data through 'N' lines, with a re-transmission request signal sent when errors are detected, and the data transmitter operates in first and second data re-transmission modes, dividing data and sending it with ground data to suppress crosstalk errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transmission speed is increased, then productivity is improved, but data error occurrences due to crosstalk increase
Solution Approach 1:
The patent divides the N-bit transmission data into multiple smaller data units (e.g., 4-bit segments) and transmits them in separate time slots. This segmentation reduces the amount of data transmitted simultaneously across adjacent lines, thereby minimizing crosstalk interference while maintaining high transmission speed through efficient time-division multiplexing.
Solution Approach 2:
The patent implements periodic re-transmission of divided data units. When errors are detected, the system periodically re-sends the divided data segments with adjusted timing and sequencing. This periodic re-transmission allows the receiver to correctly identify and reconstruct the original data while avoiding crosstalk-induced errors through synchronized transmission cycles.
2Reliability
If re-transmission mode is activated to suppress crosstalk errors, then data reliability is improved, but transmission time increases
Solution Approach 1:
The patent performs preliminary division of the N-bit data into smaller units before transmission. This preliminary segmentation allows the system to prepare multiple transmission cycles in advance, so that when re-transmission is needed, the divided data can be quickly re-sent without requiring complete re-encoding. The receiver also performs preliminary error detection to determine exactly which data units need re-transmission, minimizing unnecessary time consumption.
Solution Approach 2:
Instead of re-transmitting the entire N-bit data set, the patent implements partial re-transmission by identifying and re-sending only the specific divided data units that contained errors. This partial action approach significantly reduces the time required for re-transmission compared to complete re-sending, while still achieving reliable data recovery.
3Object-affected harmful factors
If data is divided and transmitted with ground data, then crosstalk interference is reduced, but device complexity increases
Solution Approach 1:
The patent implements a universal data division and re-transmission mechanism that can handle various data lengths and error conditions through a single standardized process. The same divided transmission framework works for different N-bit data sets, and the ground data insertion protocol is universally applied across all transmission lines. This multi-functionality reduces overall system complexity by eliminating the need for separate error correction circuits for each data type.
Solution Approach 2:
The patent introduces ground data as an intermediary element between adjacent data transmission lines. By inserting ground data units at specific positions between data units on adjacent lines, the ground data acts as a mediator that shields against crosstalk interference. This intermediary approach is simpler than implementing active noise cancellation circuits, as it passively blocks electromagnetic interference through strategic grounding.

Function Achieved in This Case
The system effectively reduces data error occurrences by re-transmitting data in divided modes with ground data, improving transmission stability and accuracy by alternating data and ground signals through transmission lines to minimize crosstalk interference.
Implementation Method 1
data transmitted through one data transmission line may be affected by electromagnetic energy generated from an adjacent data transmission line, resulting in data errors

AI summary
A data transmission system includes a data transmitter and a data receiver. The data transmitter outputs ‘N’-bit transmission data (where ‘N’ denotes a natural number which is equal to or greater than two). The data receiver receives the ‘N’-bit transmission data through ‘N’-number of data transmission lines. The data receiver transmits a re-transmission request signal to the data transmitter when the ‘N’-bit transmission data inputted to the data receiver are erroneous data. The data transmitter divides the ‘N’-bit transmission data in response to the re-transmission request signal and operates in a first data re-transmission mode so that the divided transmission data are resent, together with first ground data, to the data receiver.
