Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication chips face inflexibility and increased development and use costs due to the incompatibility of data synchronization alignment methods with multiple protocols and rates, necessitating the use of Reed-Solomon forward error correction (RS-FEC) coding, which requires alignment marks and results in inefficient resource usage.
Innovation Solution
A communication chip design incorporating multiple synchronization modules, buffer modules with FIFOs, and alignment modules to synchronize, buffer, and align data across various rate configurations, reducing logic resource occupation and waste through optimized structural design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Reed-Solomon forward error correction (RS-FEC) coding method is used with alignment marks for data synchronization, then data transmission quality is ensured, but resource usage becomes inefficient and development costs increase
Solution Approach 1:
The patent changes the synchronization parameter from alignment marks to time-interleaved parallel transmission. By adjusting the transmission timing and using multiple parallel channels with different time offsets, the system achieves synchronization without requiring additional alignment mark resources, thus improving resource usage efficiency while maintaining data transmission quality
2Ease of operation
If alignment marks are inserted into data for synchronization alignment, then data synchronization is achieved, but protocol compatibility becomes limited and development costs increase
Solution Approach 1:
The patent creates a universal synchronization mechanism that works across multiple protocols by using time-interleaved parallel transmission. The FIFO buffer and timing control system can accommodate different data rates and protocol types without requiring protocol-specific alignment marks, thereby enhancing protocol compatibility while maintaining effective data synchronization
3Adaptability or versatility
If multiple synchronization modules and alignment modules are added to support various rate configurations, then protocol compatibility is improved, but chip structure becomes complex and logic resource occupation increases
Solution Approach 1:
The patent merges multiple synchronization and alignment functions into a unified time-interleaved parallel transmission system. Instead of having separate modules for different rate configurations, the system combines them into a single architecture using FIFO buffers and centralized timing control, thereby reducing chip structure complexity while maintaining protocol compatibility
Solution Approach 2:
The patent introduces dynamic timing control and configurable FIFO buffer operations that can adapt to different data rates and protocol requirements. The system dynamically adjusts the timing parameters and buffer depths based on the specific configuration needed, eliminating the need for multiple fixed-structure modules and reducing overall device complexity
