Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pre-defined virtual processor model is used, then simulation accuracy is improved, but adaptability to custom processor designs deteriorates
Solution Approach 1:
The virtual processor model is made dynamically configurable through a configuration file that allows users to modify processor characteristics such as word length, pipeline stages, register configurations, and instruction set variations. This enables the same base model to adapt to different custom processor designs while maintaining simulation accuracy through precise parameter control.
Solution Approach 2:
The invention changes key parameters of the virtual processor model through a configuration file, including word length, pipeline depth, register count, and instruction encoding. By allowing parameter modification without redesigning the entire model, the system maintains high simulation accuracy while becoming adaptable to custom processor variants.
2Adaptability or versatility
If a custom virtual processor model is designed from scratch, then adaptability to custom designs is improved, but device complexity increases
Solution Approach 1:
A comprehensive base virtual processor model is prepared in advance with all necessary structural components, instruction sets, and simulation logic. This preliminary action eliminates the need to redesign the entire model for custom variants, reducing design complexity while maintaining full adaptability through configuration-based customization.
Solution Approach 2:
The base virtual processor model is designed to serve multiple custom processor variants universally. Through a configuration file, the same model can simulate different word lengths, pipeline configurations, and instruction sets, eliminating the need for separate custom models and reducing overall design complexity.
3Measurement precision
If detailed virtual processor models are provided, then simulation accuracy is improved, but ease of manufacture deteriorates
Solution Approach 1:
The model creation process is made dynamic through a configuration file that allows users to easily modify processor characteristics without manually coding changes. Users can adjust word length, pipeline stages, and instruction sets through simple configuration parameters, making detailed model creation accessible while maintaining high simulation accuracy.
