Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rendering methods are slow due to single-thread processing on single-core CPUs, which does not leverage the potential of multi-core CPUs for efficient image processing.
Innovation Solution

Engineering Contradiction Analysis
1Speed
If single-thread processing is used on single-core CPUs, then the system structure is simple, but the image processing speed is slow
Solution Approach 1:
The patent divides the rendering processing into multiple independent threads (command generation thread, rendering thread, copy thread) that can execute simultaneously. Each thread handles a specific stage of the rendering pipeline, allowing parallel processing of different frames and commands, thereby increasing image processing speed while maintaining manageable complexity through functional segmentation.
Solution Approach 2:
The patent transitions from single-core sequential processing to multi-core parallel processing by introducing multiple threads of execution. This dimensional change from 1D sequential to 3D parallel execution space (multiple cores × multiple threads × multiple frames) dramatically increases processing throughput without proportionally increasing system complexity.
2Productivity
If multiple threads are used for rendering processing, then the image processing speed increases, but the device complexity increases
Solution Approach 1:
The rendering pipeline is segmented into distinct functional threads: command generation thread (pre-rendering manager), rendering thread (rendering manager), and copy thread. Each thread has a clearly defined responsibility and operates independently, which increases productivity through parallel execution while controlling complexity through functional specialization and modular design.
Solution Approach 2:
The command generation thread performs preliminary actions by generating rendering commands in advance (pre-rendering) before the actual rendering occurs. This allows command preparation to be done in parallel with other operations, improving overall productivity while reducing the complexity of real-time command generation during rendering.
3Productivity
If frame-based rendering is implemented with multiprocessing, then rendering performance is maximized, but the processing coordination becomes complex
Solution Approach 1:
Each frame is processed through dedicated thread execution, with the rendering pipeline segmented into discrete stages (command generation, rendering, copy) that can be independently scheduled and executed. This segmentation allows frame-based rendering to achieve high throughput while managing synchronization complexity through structured stage transitions.
Solution Approach 2:
The patent ensures continuous useful action by maintaining a pipeline where command generation, rendering, and copy operations overlap across multiple frames. While one frame is being rendered, another frame's commands are being generated, and a third frame's results are being copied, maximizing productivity through continuous parallel operation while using the pipeline structure to manage synchronization.

AI summary
A rendering processing apparatus and method using multiprocessing are disclosed. The rendering processing method includes dividing an application execution window into frames and generating a rendering processing command for rendering processing of an image on a frame basis by a pre-rendering manager, generating a rendering image for a frame according to the generated rendering processing command by a rendering manager, and storing the generated rendering image in a memory. A task for generating a rendering processing command is divided into at least one task, a task for generating a rendering image is divided into at least one task, and the divided tasks can be processed simultaneously in a plurality of threads.
