Boot Mode Swap File Size Adjustment for Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration of information processing apparatuses that switch between boot modes deteriorates usability when booted in a mode different from the last boot mode, particularly due to the longer boot process required for generating a swap file.
Innovation Solution
The apparatus includes a memory, a storage unit for storing a swap file, and a processor that sets either a first boot mode securing a temporary file area or a second boot mode securing a swap file area, and adjusts the swap file size based on the set boot mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the apparatus is booted in the second boot mode that secures a swap file area, then a swap file can be used as a storage area of substitution of the RAM, but the boot process takes longer time when switched from the first boot mode due to generating a swap file
Solution Approach 1:
The patent applies preliminary action by pre-generating swap files in the storage unit before the actual need arises. During the first boot mode, swap files are created in advance and stored in the storage unit. When switching to the second boot mode, these pre-generated swap files are already available, eliminating the time-consuming generation process during boot-up. This resolves the contradiction by performing the swap file generation action beforehand, making the boot process faster when mode switching occurs.
2Ease of manufacture
If the storage unit is exclusively used by a swap file and a temporary file, then manufacturing cost is reduced, but usability deteriorates when booting in a different boot mode due to longer boot process
Solution Approach 1:
The patent applies dynamics by making the storage unit configuration flexible and adaptable based on boot mode. The storage unit can dynamically switch between being exclusively dedicated to swap files (second boot mode) and being shared with temporary file areas (first boot mode). This dynamic reconfiguration allows the system to optimize for manufacturing cost when in second boot mode while maintaining usability when switching to first boot mode, as the storage unit can adapt its structure to meet the requirements of either mode without permanent degradation.

AI summary
An information processing apparatus that is capable of reducing deterioration of usability resulting from booting in a boot mode that is different from a boot mode of the last boot time. The information processing apparatus includes a memory, a storage unit that stores a swap file used as a substituted storage area of the memory, and at least one processor that executes instructions stored in the memory to set either of a first boot mode that preferentially secures an area storing a temporary file in the storage unit and a second boot mode that preferentially secures an area storing the swap file in the storage unit, and adjust a size of the swap file depending on a boot mode set.
