Dynamic Power Configuration for Memory Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face inefficiencies in power management, leading to increased energy consumption and heat dissipation, as existing technologies lack effective methods to dynamically adjust power settings based on performance metrics and usage patterns.
Innovation Solution
A method involving a host service that monitors performance metrics of a memory device, predicts energy requirements, generates a power configuration profile, and sends it to a management device to modify power controller parameters via a side-band bus, optimizing power efficiency by adjusting voltage regulator and power controller settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power settings are statically configured, then device complexity is reduced, but power efficiency deteriorates due to inability to adapt to varying usage patterns
Solution Approach 1:
The patent implements dynamic power management by continuously monitoring performance metrics (memory bandwidth, power consumption, temperature) and adjusting power configuration parameters in real-time based on actual usage patterns, transforming static power settings into adaptive dynamic control
Solution Approach 2:
The system establishes a feedback loop where power metrics are monitored, analyzed against performance requirements, and used to generate updated power configurations that are applied back to the system, creating continuous optimization cycles
2Speed
If power consumption is increased, then processing speed is improved, but energy efficiency deteriorates
Solution Approach 1:
The patent dynamically adjusts power configuration parameters based on monitored performance metrics, allowing the system to optimize the balance between processing speed and power consumption by adapting settings to actual workload demands rather than using fixed high-power configurations
Solution Approach 2:
The system changes power-related parameters (voltage, frequency, power state) based on monitored performance metrics and predicted energy requirements, enabling the system to achieve necessary processing speeds only when and where needed, thereby improving overall energy efficiency
3Use of energy by moving object
If power configuration is dynamically adjusted, then power efficiency is improved, but device complexity increases
Solution Approach 1:
The system implements self-service power management where the information handling system autonomously monitors its own performance metrics, predicts energy requirements, generates appropriate power configurations, and applies adjustments without requiring external intervention, thereby managing complexity internally while delivering efficiency benefits
