Engineering Contradiction Analysis
1Power
If the network size increases, then the computational power and simulation capability improve, but the simulation time increases and real-time performance deteriorates
Solution Approach 1:
The patent segments the neural network simulation across multiple platforms (CPU, GPU, FPGA, ASIC) with different computational characteristics. Large networks are divided into portions that can be simulated in parallel on specialized hardware, reducing overall simulation time while maintaining real-time performance for critical portions.
Solution Approach 2:
The system dynamically selects and switches between different simulation platforms based on network size, complexity, and real-time requirements. The compilation system generates platform-specific code that adapts to varying computational demands, allowing the simulation to maintain optimal performance across different operating conditions.
2Productivity
If specialized hardware is used, then the simulation speed and efficiency improve, but the device complexity and hardware requirements increase
Solution Approach 1:
The patent creates a universal compilation system that generates executable code for multiple target platforms (CPU, GPU, FPGA, ASIC) from a single neural network description. This multi-functional approach allows the same network model to be deployed on different hardware configurations without requiring separate development efforts for each platform.
Solution Approach 2:
The compilation system changes parameters such as parallelization degree, memory allocation, and computational kernel optimization based on the target platform's characteristics. By adjusting these parameters during code generation, the system optimizes simulation speed for each specific hardware configuration without increasing overall device complexity.
3Measurement precision
If the network complexity increases, then the computational accuracy and model fidelity improve, but the adaptability to different platforms decreases
Solution Approach 1:
The patent introduces an intermediate representation layer between the neural network description and platform-specific implementation. This intermediary compilation system translates the abstract network model into optimized code for different platforms while preserving computational accuracy. The intermediate representation maintains the semantic meaning of complex operations regardless of the target platform.
4Use of energy by moving object
If platform-specific optimizations are applied, then the computational efficiency on each platform improves, but the code complexity and development time increase
Solution Approach 1:
The patent applies platform-specific optimizations during the code generation phase rather than requiring manual optimization for each platform. The compilation system performs preliminary actions by automatically analyzing the target platform's characteristics and generating optimized code accordingly, eliminating the need for developers to write separate optimized code for each platform.
