Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer systems face inefficiencies in memory device placement, leading to varying data transfer latencies due to non-uniform access times and changing environmental and usage patterns, which can result in suboptimal performance.
Innovation Solution
A method and system that determine optimal placement of memory devices in memory slots based on performance metrics and predefined rules, such as placing memory devices with lower latencies closest to the memory controller, using a logic circuit or controller to assess and reconfigure the placement for maximum efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If memory devices are placed in fixed positions in memory slots, then system stability is maintained, but data transfer latency varies due to non-uniform access times and environmental changes
Solution Approach 1:
The patent implements dynamic memory device placement by allowing the memory controller to reassign memory devices to different physical slots based on real-time performance metrics and usage patterns. This dynamic reconfiguration enables the system to adapt to changing environmental conditions and optimize access times, directly resolving the contradiction between maintaining stable placement and reducing access time variability.
Solution Approach 2:
The system changes the parameter of memory device physical location based on performance metrics such as access time, temperature, and usage frequency. By monitoring these parameters and repositioning memory devices accordingly, the system optimizes data transfer speed while minimizing access time variability, effectively resolving the technical contradiction.
2Loss of time
If memory devices are strategically placed closer to the memory controller based on performance metrics, then data transfer latency is reduced, but system complexity increases due to monitoring and reconfiguration requirements
Solution Approach 1:
The memory controller automatically monitors performance metrics of memory devices and performs self-service by reconfiguring the placement of memory devices without external intervention. This self-managing approach reduces data transfer latency while minimizing the perceived complexity for users, as the system handles the optimization autonomously based on predefined performance criteria.
3Productivity
If performance metrics are continuously monitored to optimize memory placement, then system performance is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic monitoring and reconfiguration of memory device placement rather than continuous operation. Performance metrics are evaluated at predetermined intervals or based on trigger events, allowing the system to maintain improved memory access efficiency while reducing energy consumption associated with constant monitoring and reconfiguration operations.
