Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data is stored in Type III unum format for neuromorphic operations, then data precision and accuracy are maintained, but operation difficulty and processing complexity increase
Solution Approach 1:
The patent introduces format conversion circuitry as an intermediary component that translates data between Type III unum format and analog format. This mediator enables neuromorphic operations to be performed on analog data while preserving the precision benefits of unum format, effectively resolving the contradiction between maintaining precision and reducing operational complexity.
Solution Approach 2:
The patent changes the format parameter of data representation by converting between Type III unum and analog formats based on operational requirements. This parameter transformation allows the system to leverage the precision of unum format for data storage and the operational simplicity of analog format for neuromorphic computations.
2Productivity
If data is converted between formats for neuromorphic operations, then processing efficiency improves, but conversion overhead and system complexity increase
Solution Approach 1:
The patent merges the format conversion functionality directly into the neuromorphic processing system, integrating digital-to-analog and analog-to-digital conversion circuits with the neuromorphic operation units. This integration reduces the overhead of separate conversion operations and streamlines the overall processing pipeline.
3Speed
If analog format is used for neuromorphic operations, then operation speed and efficiency improve, but data storage and precision maintenance become more difficult
Solution Approach 1:
The patent performs preliminary conversion of data from Type III unum format to analog format before neuromorphic operations are executed. This advance preparation ensures that data is in the optimal format for high-speed analog processing while the precision characteristics of unum format are preserved through the conversion process.
Solution Approach 2:
The format conversion circuitry acts as an intermediary that bridges the precision advantages of digital unum format and the speed advantages of analog format, enabling the system to achieve both high precision and fast operation speeds through coordinated format transformations.
