Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If hyperdimensional computing is implemented on FPGAs using traditional methods, then computing speed is improved, but implementation time and complexity increase significantly
Solution Approach 1:
The patent applies parameter changes by introducing a template-based configuration system where hyperdimensional computing parameters (vector dimension, number of processing elements, pipeline stages) can be adjusted without redesigning the entire system. This allows the same FPGA architecture to be reconfigured for different HD computing requirements, reducing implementation complexity while maintaining high computing speed.
Solution Approach 2:
The patent implements universality by creating a multi-functional FPGA template that can perform various hyperdimensional computing operations (encoding, decoding, similarity search, classification) using the same hardware structure. This universal template reduces implementation complexity by eliminating the need to design separate circuits for each HD operation.
2Measurement precision
If hyperdimensional computing is implemented on FPGAs with high accuracy requirements, then classification accuracy is improved, but resource consumption and implementation time increase
Solution Approach 1:
The patent applies dynamics by implementing adjustable precision modes in the FPGA template, allowing the system to dynamically switch between different accuracy levels based on application requirements. The template can be configured to use full-precision or reduced-precision arithmetic operations, enabling users to balance accuracy against resource consumption and implementation time.
Solution Approach 2:
The patent implements local quality by allowing different parts of the HD computing pipeline to use different precision levels. For example, the encoding stage may use lower precision while the similarity search stage uses higher precision, optimizing overall resource consumption while maintaining necessary accuracy for each specific operation.
3Productivity
If hyperdimensional computing is implemented on FPGAs with high parallelism, then processing throughput is improved, but power consumption and resource usage increase
Solution Approach 1:
The patent applies partial action by implementing a configurable parallelism level in the FPGA template, where users can activate only the necessary number of processing elements and pipeline stages required for their specific application. This allows the system to achieve adequate throughput without deploying excessive parallel resources that would increase power consumption unnecessarily.
Solution Approach 2:
The patent implements segmentation by dividing the HD computing pipeline into modular stages (encoding, processing, decoding, search) that can be independently configured and activated. This segmentation allows the system to enable only the necessary stages for a given task, reducing power consumption while maintaining required processing throughput.
