PCB Data Processing Link Cross Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current switching chips face challenges in ensuring a one-to-one correspondence between physical link ports and data transmission links due to link cross occurrences on a Printed Circuit Board (PCB), leading to inefficiencies and increased complexity, especially with the addition of logical links that complicate real-time clock tree analysis.
Innovation Solution
A data processing method and apparatus that configures channel and link identifiers based on link cross information on the PCB to maintain a one-to-one correspondence between data transmission links and physical link ports, avoiding the need for logical links and thus reducing complexity and clock-related burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If link cross occurs on PCB, then physical link ports can be connected flexibly, but one-to-one correspondence between physical link ports and data transmission links is broken
Solution Approach 1:
The patent introduces an intermediary mapping mechanism that translates between physical link port identifiers and data transmission link identifiers through a configured correspondence relationship. This intermediary layer resolves the mismatch caused by link crosses, allowing flexible physical connections while maintaining reliable one-to-one correspondence in the data transmission domain.
2Reliability
If logical links are added to handle link cross, then correspondence can be maintained, but real-time clock tree analysis complexity increases
Solution Approach 1:
The patent extracts the link correspondence mapping function from the clock tree analysis domain and places it in the data transmission layer. By separating these functions, the solution maintains reliable correspondence without burdening the clock tree analysis with additional logical link complexities, thus reducing overall system complexity.
3Power
If multiple data transmission channels and links are implemented, then bandwidth is increased, but scalability and correspondence management become more difficult
Solution Approach 1:
The patent segments the data transmission system into multiple independent channels, each with its own set of data transmission links. The correspondence management is standardized through a unified mapping mechanism that operates independently for each channel, enabling high bandwidth through parallel channels while maintaining manageable scalability through modular correspondence configuration.
