Line Buffer Partitioning for Multi-Plane Image Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixed size of line buffers in image synthesis apparatuses requires multiple buffers for simultaneous display of multiple planes, leading to increased memory costs.
Innovation Solution
Each target line buffer is divided into sections to store row pixel data of multiple planes, with configurable depths based on the planes' ratios and priorities, optimizing space utilization.

Engineering Contradiction Analysis
1Ease of manufacture
If each line buffer is used to store row pixel data of one single plane, then the storage is simple and fixed, but more line buffers are required for simultaneous display of multiple planes, causing significant increase in memory cost
Solution Approach 1:
Each line buffer is configured to serve multiple planes simultaneously by dividing the buffer into multiple sections, where each section can store row pixel data for a different plane. This multi-functional configuration allows a single line buffer to replace multiple dedicated buffers, reducing memory cost while maintaining the ability to display multiple planes concurrently
Solution Approach 2:
The line buffer is segmented into multiple sections, with each section assigned to store data for a specific plane. This segmentation enables efficient organization and management of multi-plane data within a single buffer, allowing the system to handle multiple planes without requiring separate buffers for each plane
2Device complexity
If the size of each line buffer is fixed, then the buffer design is simple, but it cannot adapt to different numbers of planes, requiring more buffers when displaying multiple planes simultaneously
Solution Approach 1:
The line buffer configuration is made dynamic by allowing the buffer to be divided into different numbers of sections based on the number of planes that need to be displayed simultaneously. This dynamic adaptability enables the same fixed-size buffer to efficiently accommodate varying numbers of planes without requiring changes to the buffer's fundamental design or additional buffers
