Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard communication protocol is used between chiplets, then communication compatibility is improved, but communication failure occurs when detailed configurations of chiplets differ
Solution Approach 1:
The patent introduces a conversion device as an intermediary component between chiplets with different protocols. This conversion device receives data from one chiplet, converts it according to the target chiplet's protocol specifications, and transmits it to the other chiplet. The conversion device acts as a mediator that enables communication between heterogeneous chiplets without requiring them to use the same protocol directly, thus resolving the contradiction between protocol standardization and configuration diversity.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting conversion information based on the detailed configurations of communicating chiplets. The conversion device modifies parameters such as data format, encoding schemes, and transmission protocols according to the specific requirements of each chiplet pair. This allows the system to maintain communication compatibility while adapting to different detailed configurations, thereby preventing communication failures.
2Ease of manufacture
If chiplets are designed with independent configurations, then design flexibility is improved, but interoperability between chiplets deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the chiplet system into independently designable units (chiplets) while introducing a standardized conversion interface. Each chiplet can be designed and manufactured independently with its own optimal configuration, while the conversion device provides a unified interface layer that ensures interoperability. This segmentation allows design flexibility at the chiplet level while maintaining system-level compatibility.
Solution Approach 2:
The conversion device embodies universality by serving multiple functions: protocol conversion, data format transformation, and compatibility bridging. It can handle various chiplet configurations and protocols, making the system universally compatible regardless of the specific detailed configurations of individual chiplets. This multi-functional conversion device enables independent chiplet designs while ensuring broad interoperability across the system.
