Dual Clock Resume Control for Precise Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses with resume functions, which rely on standard RTCs, cannot accurately manage the starting time for specific-purpose resume processing, limiting their effectiveness.
Innovation Solution
Incorporating a first and second clock, along with a controller, to manage resume processing for both general and specific purposes, allowing for precise timing and power management by using auxiliary power to supply clocks and timers, enabling the system to resume operations of all devices or specific programs as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a standard RTC is used for resume processing, then the system can perform general resume functions, but the starting time for specific-purpose resume processing cannot be accurately managed
Solution Approach 1:
The clock system is segmented into multiple independent clocks (first clock for general purpose, second clock for specific purpose). Each clock operates independently to manage different timing requirements, allowing precise time management for specific-purpose resume processing without affecting the overall system complexity significantly.
Solution Approach 2:
The controller is designed to universally manage multiple clocks and coordinate their operations. It can selectively activate the appropriate clock based on the resume processing type, making the time management system multi-functional and adaptable to both general and specific-purpose resume scenarios.
2Reliability
If resume processing is performed for all devices, then complete system restoration is achieved, but unnecessary power consumption occurs for devices not requiring resume
Solution Approach 1:
The resume processing is applied locally to only those devices or programs that require restoration. The controller identifies specific targets for resume processing based on the second clock's timing signals, ensuring that power is consumed only for necessary restoration operations rather than blanket system-wide resume.
Solution Approach 2:
Instead of performing full system resume (excessive action), the system performs partial resume only for specific devices or programs that need restoration. This selective approach reduces power consumption while maintaining reliability for critical functions.
3Measurement precision
If multiple clocks are implemented for precise timing, then specific-purpose resume timing is accurate, but the device complexity increases
Solution Approach 1:
The controller serves as an intermediary that manages the complexity of coordinating multiple clocks. It translates the timing signals from the first and second clocks into appropriate resume actions, shielding the user from the underlying complexity while maintaining accurate timing for specific-purpose resume processing.

AI summary
According to one embodiment, there is provided an information processing apparatus, including a first clock portion to output a first signal when a measurement value coincides with first set time, a second clock portion to output a second signal when a measurement value coincides with second set time, and a controller to perform control to execute resume processing for a first purpose when the first clock portion outputs the first signal, and execute resume processing for a second purpose when the second clock portion outputs the second signal.
