Engineering Contradiction Analysis
1Productivity
If multiple decoders are used to convert multiple pieces of compressed image data in parallel, then processing speed is improved, but circuit dimension and device complexity increase
Solution Approach 1:
The patent implements a shared converter that serves multiple decoders, allowing a single conversion circuit to process data from different decoding units. This multi-functional approach enables parallel decoding of multiple compressed image data streams while avoiding the need for separate conversion circuits for each decoder, thus improving processing speed without proportionally increasing circuit dimension.
Solution Approach 2:
The patent merges the conversion function into a shared resource that is commonly used by multiple decoders. By combining the conversion operations into a single circuit that can be dynamically allocated to different decoders, the system achieves parallel processing capability while reducing the total circuit dimension compared to having dedicated conversion circuits for each decoder.
2Device complexity
If a common converter is shared among multiple decoders, then circuit dimension is reduced, but processing speed may be compromised due to shared resource contention
Solution Approach 1:
The patent employs dynamic switching control that adaptively allocates the shared converter to different decoders based on current processing needs. The switcher dynamically changes the destination decoder among multiple decoders, enabling the system to optimize resource utilization and maintain appropriate processing speeds for each compressed image data stream while sharing the conversion circuit.
Solution Approach 2:
The patent segments the processing of compressed image data into discrete units that can be handled by the shared converter in a time-multiplexed manner. By processing data in segmented portions and switching between decoders at appropriate intervals, the system maintains processing efficiency while utilizing the shared conversion resource.
3Productivity
If parallel conversion of multiple compressed image data is implemented, then throughput is improved, but control complexity increases
Solution Approach 1:
The patent introduces a switcher as an intermediary component that manages the interaction between multiple decoders and the shared converter. This mediator component simplifies control by providing a centralized switching mechanism that routes data flow between decoders and the conversion circuit, reducing the overall control complexity compared to direct management of multiple parallel conversion paths.
