Memory Page Allocator Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer systems face challenges in efficiently managing memory resources to balance power conservation and performance, as existing methods do not effectively allocate memory space across multiple modules to meet varying power consumption criteria and performance requirements.
Innovation Solution
A method and system for memory management that includes a page allocator which identifies the most suitable memory module based on a specified power management policy, allocating memory space while enabling or disabling modules to conserve power or enhance performance, using a memory management unit to translate virtual addresses to physical addresses and manage memory attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If memory modules are kept active to satisfy performance requirements, then system performance is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts memory module power states based on real-time performance requirements and workload characteristics. The memory management unit monitors system demands and transitions memory modules between active and low-power states, enabling adaptive balance between performance and power consumption rather than using fixed allocation strategies
Solution Approach 2:
The invention changes the power state parameter of memory modules dynamically. By transitioning memory modules between different power states (fully active, partially active, low-power standby), the system can adjust power consumption levels while maintaining adequate performance based on current system needs
2Quantity of substance
If memory space is allocated across multiple memory modules, then available memory capacity is improved, but device complexity increases
Solution Approach 1:
The memory management unit implements self-service mechanisms by automatically monitoring system performance, evaluating workload characteristics, and making autonomous decisions about memory module power states and allocation. This eliminates the need for complex external control systems or manual configuration, reducing overall system complexity while managing multiple memory modules effectively
3Loss of energy
If memory modules are disabled to conserve power, then power consumption is reduced, but system performance deteriorates
Solution Approach 1:
Instead of completely disabling memory modules, the system applies partial action by transitioning them to low-power standby states that consume significantly less power while retaining basic functionality. This allows the system to achieve substantial power savings while maintaining the capability to quickly reactivate modules when performance demands increase
