Engineering Contradiction Analysis
1Device complexity
If a single special function register (SFR) and one synchronization logic are used to control all modules, then the system structure is simple, but the processing performance and efficiency deteriorate
Solution Approach 1:
The patent divides the single SFR into multiple SFRs (first SFR, second SFR, third SFR, etc.), each responsible for controlling specific processing modules. Similarly, the single synchronization logic is segmented into multiple independent synchronization logics (first, second, third, etc.), where each synchronization logic independently controls its associated modules. This segmentation allows parallel processing of different video frames by different module groups, thereby improving processing performance while maintaining manageable system complexity through modular organization.
2Ease of operation
If all modules are controlled by one synchronization logic, then the control structure is unified, but the ability to perform high-performance operations deteriorates
Solution Approach 1:
The control structure is segmented into multiple independent synchronization logics, each managing specific processing modules. For example, the first synchronization logic controls the first processing module, the second synchronization logic controls the second processing module, and so on. Each synchronization logic independently generates synchronization signals for its associated modules, enabling parallel high-performance operations on different video frames while maintaining a clear and organized control structure through this modular segmentation.
Solution Approach 2:
The system dynamically assigns different video frames to different processing modules based on the synchronization signals. Each synchronization logic can independently control the timing and sequence of operations for its associated modules, allowing the system to adaptively optimize processing performance for different video frames and operational requirements, thereby enabling high-performance operations while maintaining ease of control.
3Productivity
If multiple processing modules operate simultaneously with independent clock signals, then the processing efficiency improves, but the power consumption increases
Solution Approach 1:
Each processing module operates periodically based on its dedicated synchronization signal from its associated synchronization logic. The synchronization signals are generated periodically to coordinate the operation of processing modules, allowing them to activate and process video frames only when needed. This periodic operation enabled by independent synchronization logics improves processing efficiency by allowing simultaneous operations while reducing power consumption by keeping modules in a low-power state during idle periods between synchronization cycles.

AI summary
A multimedia system includes a main special function register (SFR) configured to store SFR information; a plurality of processing modules each configured to process frames of data, based on the SFR information; and a system control logic configured to control operations of the main SFR and the plurality of processing modules. The plurality of processing modules may process data of different frames at the same time period.
