Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing systems face challenges in configuring internal devices during initialization, leading to potential latency and damage due to incorrect configurations, especially when power states change, as existing methods lack flexibility and may require additional pins for configuration.
Innovation Solution
A computing system configures devices with either first or second configuration data based on the availability of backup power before initialization, using a power circuit to deliver standby power and a battery to provide backup power, allowing devices to retrieve and apply appropriate configuration data from memory to registers, thereby reducing latency and enabling multiple configurations across platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration data is loaded during initialization, then device functionality is established, but system boot-up latency increases
Solution Approach 1:
The patent applies preliminary action by loading configuration data into memory during the power-on self-test (POST) phase, before the operating system initialization. This allows configuration data to be ready in advance, reducing boot-up latency while ensuring correct device functionality is established before full system operation begins.
2Adaptability or versatility
If additional pins are used for configuration data storage, then configuration flexibility is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by using existing memory structures and power management infrastructure for configuration data storage and retrieval. Instead of adding dedicated pins or separate storage components, the system utilizes available memory resources and power states, thereby achieving configuration flexibility without increasing device complexity or pin count.
3Use of energy by moving object
If configuration is performed without backup power, then power consumption is reduced, but configuration reliability deteriorates during power loss
Solution Approach 1:
The patent applies dynamics by implementing power state detection that allows the system to dynamically adjust configuration behavior based on available power. When backup power is detected, the system can perform more thorough configuration operations and maintain configuration state during power transitions. When backup power is unavailable, the system uses minimal power consumption modes while maintaining essential configuration functionality.

AI summary
According to examples, an apparatus may include a power circuit to transmit standby power to a device, a memory associated with the device to maintain first configuration data and second configuration data and a battery to provide backup power to the device. The device may, following a loss and a recovery of the standby power to the device, determine whether the backup power was lost during the loss of the standby power. The device may also, based on a determination that the backup power was lost during the loss of the standby power, read the first configuration data or may, based on a determination that the backup power was not lost during the loss of the standby power, read the second configuration data. The device may further apply the read one of the first configuration data or the second configuration data to configure the device.
