Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As semiconductor devices operate at faster data transmission speeds, the probability of error occurrence increases, necessitating advanced design techniques for reliable data transmission, including the use of error codes like cyclic redundancy checks and error correction codes, but existing systems lack efficient mechanisms to manage error detection and correction in high-error scenarios.
Innovation Solution
A semiconductor system is designed with multiple devices that perform independent error check operations based on error check enablement signals and clock signals, generating error check signals that are disabled after a predetermined number of error occurrences, thereby preventing further error check operations and maintaining data transmission reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transmission speed is increased to improve operation speed, then productivity is improved, but error occurrence probability increases
Solution Approach 1:
The patent implements a feedback mechanism where error check circuits continuously monitor data transmission and provide feedback signals to the controller. When errors are detected, the system adjusts its operation by disabling error check operations after a predetermined number of error occurrences, thereby resolving the contradiction between high-speed operation and reliable data transmission.
2Reliability
If error check operations are continuously performed to improve data transmission reliability, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by making the error check operation configurable and adaptable. The system dynamically adjusts error check behavior based on error occurrence patterns, disabling further error check operations after a predetermined number of errors. This dynamic approach maintains reliability while avoiding the complexity of continuously performing error checks in all scenarios.
3Reliability
If error check operations are disabled after predetermined error occurrences to prevent further errors, then reliability is maintained, but loss of information increases
Solution Approach 1:
The patent implements beforehand cushioning by establishing a threshold of predetermined error occurrences before disabling error check operations. This cushioning approach allows the system to tolerate a certain number of errors while maintaining error check functionality, and only disables operations when the error rate exceeds the predetermined threshold, thus balancing reliability maintenance with information loss prevention.
