Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face inefficiencies in utilizing multiple cores for analysis processing, leading to increased memory requirements and decreased processing speed due to ineffective core utilization and reliance on slower storage devices for memory supplementation.
Innovation Solution
An image processing apparatus with multiple control sections that perform parallel analysis and rendering processing, where one control section discontinues analysis processing based on storage capacity information and a predetermined threshold value to optimize memory usage and prevent processing speed decreases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If analysis processing is performed parallelly with multiple cores, then processing speed is improved, but memory capacity requirement increases
Solution Approach 1:
The patent divides the intermediate language data into multiple segments corresponding to different page ranges, with each control section processing a specific segment. This segmentation allows multiple cores to work in parallel on different data portions simultaneously, improving processing speed while each core uses only the memory required for its specific segment rather than requiring all cores to access the entire dataset.
Solution Approach 2:
The patent introduces a new dimension of organization by arranging intermediate language data in a sequential structure across storage sections, where data is divided into first, second, and subsequent intermediate language data portions. This dimensional organization allows control sections to access only the specific data portions they need, reducing overall memory capacity requirements while maintaining parallel processing capability.
2Quantity of substance
If storage device is used to supplement memory capacity, then cost is reduced, but processing speed decreases
Solution Approach 1:
The patent performs preliminary organization of intermediate language data into sequentially arranged portions before processing begins. By pre-dividing and organizing the data into distinct segments that can be independently accessed, the system enables control sections to quickly locate and process their assigned data portions without requiring slow sequential access to entire datasets, thus maintaining high processing speed while using cost-effective storage devices.
Solution Approach 2:
The patent introduces an intermediary data structure where intermediate language data is organized into distinct portions (first intermediate language data, second intermediate language data, etc.) that act as intermediaries between the storage device and the control sections. This intermediary organization allows efficient data retrieval by control sections, bridging the speed gap between storage devices and traditional memory while reducing overall memory capacity requirements.
3Quantity of substance
If one core performs analysis processing while others wait, then memory capacity is reduced, but core utilization efficiency decreases
Solution Approach 1:
The patent segments the analysis processing workload by dividing intermediate language data into distinct portions assigned to different control sections. Each control section independently processes its assigned segment without waiting for other sections, achieving both reduced memory capacity requirements (since each section only needs its segment in memory) and high core utilization efficiency (since all cores work simultaneously on different segments).
