Engineering Contradiction Analysis
1Productivity
If multiple image processing circuits generate different image data formats simultaneously, then processing speed and functionality are improved, but memory management complexity increases
Solution Approach 1:
The coordination circuit receives storing requests from multiple image processing circuits and determines the storage order in advance based on priority levels. By pre-establishing the storage sequence before actual data writing, the system avoids memory conflicts and ensures efficient multi-format image data storage without requiring complex real-time memory arbitration.
2Adaptability or versatility
If image data is converted between formats (e.g., CMYK to RGB), then adaptability to different output devices is improved, but image quality deteriorates
Solution Approach 1:
The system divides image processing into separate processing circuits, each dedicated to generating specific image data formats (e.g., one circuit for CMYK format, another for RGB format). By segmenting the processing functions, each circuit can optimize for its specific format without compromising quality, while the coordination circuit manages the overall workflow and storage prioritization.
3Productivity
If multiple storing requests are handled simultaneously, then productivity is improved, but data storage accuracy and order control become difficult
Solution Approach 1:
The coordination circuit establishes the storage order in advance by receiving and processing storing requests according to their priority levels before actual data writing occurs. This preliminary determination of storage sequence ensures that high-priority data is stored first while maintaining accurate order control, even when multiple circuits generate data simultaneously.
