Data Frame Buffer Management for Image Processing Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data processing, particularly in image processing, the increasing performance of image processing modules leads to data interaction delays between video input sources and processing modules, resulting in frame skips during full-frame processing, which affects processing accuracy.
Innovation Solution
A data processing system with multiple data frame buffer regions and a state register is implemented, allowing cyclic use of buffer regions to manage data frame processing independently of the image processing controller's state updates, thereby reducing delays and preventing frame skips.

Engineering Contradiction Analysis
1Power
If image processing module performance is improved, then processing speed increases, but data interaction delay between video input source and processing module increases
Solution Approach 1:
The buffer memory is divided into multiple buffer regions (first buffer region, second buffer region, etc.), allowing parallel data storage and processing. This segmentation enables the system to maintain high processing performance while reducing interaction delays through concurrent operations in different buffer regions.
2Manufacturing precision
If full-frame processing is performed, then processing completeness is improved, but frame skips occur affecting processing accuracy
Solution Approach 1:
The system performs preliminary actions by pre-configuring multiple buffer regions and establishing buffer region management logic before processing begins. The state register is pre-initialized to track buffer region states, enabling the system to maintain processing accuracy while preventing frame skips through proactive buffer management.
Solution Approach 2:
The state register provides continuous feedback on the states of multiple buffer regions, enabling the buffer region management logic to dynamically adjust processing operations. This feedback mechanism ensures processing accuracy is maintained while preventing frame skips by coordinating read/write operations based on real-time buffer states.
