Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the CPU enters the operating system before image processing is complete, then the image output speed is improved, but the system stability deteriorates
Solution Approach 1:
The patent divides the system into two independent parts: a hardware image processing circuit that handles image signal processing autonomously, and a CPU that enters the operating system independently. This segmentation allows the CPU to proceed with the operating system without waiting for image processing to complete, improving image output speed while maintaining system stability through independent operation of each component.
Solution Approach 2:
The patent implements preliminary configuration where the hardware image processing circuit is pre-configured with necessary parameters and settings before the CPU enters the operating system. This preliminary setup allows the image processing to begin immediately without requiring the CPU to complete its initialization first, thereby improving output speed while the pre-configured hardware ensures stable operation.
2Reliability
If the CPU waits for the sensing and processing circuits to complete before entering the operating system, then the system stability is improved, but the image output speed deteriorates
Solution Approach 1:
The system is segmented into independent hardware circuitry for sensing and processing that operates autonomously from the CPU. This allows the CPU to enter the operating system without waiting for the hardware circuits to complete their initialization, achieving both fast image output and system stability through independent parallel operation.
3Speed
If the CPU enters the operating system immediately, then the image output speed is improved, but the configuration completeness deteriorates
Solution Approach 1:
The hardware image processing circuit is pre-configured with all necessary operational parameters, processing algorithms, and system settings before the CPU enters the operating system. This preliminary configuration ensures that the hardware circuit can independently perform complete image processing tasks without requiring additional CPU intervention, thus maintaining configuration completeness while enabling immediate CPU initialization for fast image output.
