Bi-directional Multiplexer Configuration Error Checker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bi-directional multiplexing infrastructures face challenges in detecting invalid configurations, where a sink driven by a source cannot select other allocated sources, leading to complex debugging and configuration issues.
Innovation Solution
An apparatus with multiplexer decoder logic and a configuration error checker monitors control signals across forward and backward multiplexers, using standard-cells like AND- and OR-gates to determine if a source is used more than once, generating error information to identify invalid configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bi-directional multiplexing infrastructure is implemented with multiple sources and sinks, then connectivity and data flow capability are improved, but configuration complexity and difficulty of detecting invalid configurations increase
Solution Approach 1:
The patent implements a configuration error detector that continuously monitors backward multiplexer control signals and provides feedback about invalid configurations. The detector evaluates whether multiple sinks are simultaneously selecting the same source and generates error information when conflicts are detected, enabling real-time detection and correction of configuration errors in bi-directional multiplexing systems.
2Adaptability or versatility
If bi-directional multiplexing infrastructure is implemented with multiple sources and sinks, then connectivity and data flow capability are improved, but debugging difficulty increases
Solution Approach 1:
The configuration error detector provides automated feedback about configuration errors, eliminating the need for manual debugging of invalid configurations. The detector monitors control signals and automatically identifies when multiple sinks select the same source, providing clear error information that significantly reduces debugging time and complexity.
Solution Approach 2:
The system performs self-diagnosis by automatically detecting and reporting configuration errors without external intervention. The error detector monitors the multiplexer configuration and independently identifies invalid states, enabling the system to self-correct or alert operators to problems without requiring complex external debugging tools.
3Reliability
If configuration error detector is added to monitor control signals, then detection of invalid configurations is improved, but device complexity increases
Solution Approach 1:
The configuration error detector acts as an intermediary component that monitors backward multiplexer control signals without disrupting the primary data flow. It evaluates control signals to detect conflicts where multiple sinks select the same source, providing error detection capability while maintaining the existing multiplexing architecture and minimizing added complexity.
