Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-processor systems, performance is hindered when processors operate at different speeds, with the slowest processor limiting the group's performance, and existing methods struggle to optimize performance within a specified power budget.
Innovation Solution
A controller dynamically adjusts the clock frequencies of processors within a group to synchronize them and ensure they operate within a power budget by using models that calculate target clock speeds based on workload factors and power consumption, allowing for increased performance by optimizing clock frequencies.

Engineering Contradiction Analysis
1Productivity
If processors operate at different speeds, then individual processor performance may be optimized, but the overall processor group performance is limited by the slowest processor
Solution Approach 1:
The patent changes the clock frequency parameter of processors dynamically. A controller monitors the performance of multiple processors and adjusts their clock frequencies to synchronize them, ensuring they complete tasks at the same rate. This prevents blocking and maximizes the overall productivity of the processor group by eliminating the performance bottleneck caused by the slowest processor.
2Productivity
If clock frequencies are increased to improve performance, then execution speed increases, but power consumption exceeds the specified power budget
Solution Approach 1:
The patent implements dynamic adjustment of clock frequencies based on real-time performance monitoring and power budget constraints. Instead of using fixed high frequencies, the controller continuously adapts the operating frequencies of processors to achieve the highest possible execution speed while remaining within the specified power budget. This dynamic approach allows the system to optimize performance without permanently exceeding energy constraints.
3Productivity
If clock frequencies are synchronized across processors, then overall processor group performance improves, but complex control mechanisms are required to manage frequency adjustments
Solution Approach 1:
The patent employs a feedback-based control mechanism where a controller monitors the performance metrics of multiple processors and uses this information to adjust their clock frequencies. The controller receives feedback about processor speeds and power consumption, then makes centralized decisions to synchronize frequencies. This feedback loop automates the complexity of coordination, making the synchronization process manageable and adaptive to changing conditions.
