Keephot Instructions for Power Delivery Network Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hardware emulators experience significant voltage fluctuations during load steps, leading to inefficient power management and potential logical errors due to insufficient capacitance and IR drops in the power delivery network, causing transistors to malfunction during high-power applications.
Innovation Solution
Implementing keephot instructions and cycles that allow processors to continuously consume power between mission cycles, mitigating power-load drops and rises by incrementally activating processor clusters, thereby reducing the severity of load steps and maintaining a constant voltage level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If processors execute instructions synchronously in lock step mode, then emulation accuracy is improved, but power consumption stability deteriorates due to sudden load steps
Solution Approach 1:
The system performs preliminary actions by executing keephot instructions before mission instructions to gradually warm up the power delivery network. This preliminary power consumption prevents sudden load steps when mission cycles begin, thereby maintaining both emulation accuracy and power stability.
Solution Approach 2:
The execution cycle is segmented into two distinct phases: keephot cycles that consume power to stabilize the power delivery network, and mission cycles that perform actual emulation work. This segmentation allows the system to separate power stabilization from computation, resolving the contradiction between accurate synchronous execution and stable power consumption.
2Stability of the object's composition
If capacitance is increased to compensate for voltage drops, then voltage stability is improved, but device complexity increases
Solution Approach 1:
Instead of relying on large capacitance to bridge gaps between execution cycles, the system maintains continuous useful action by executing keephot instructions that consume power continuously. This continuous power consumption eliminates voltage drops without requiring increased capacitance, thereby maintaining voltage stability while avoiding increased device complexity.
3Use of energy by moving object
If processors are activated intermittently between mission cycles, then power efficiency is improved, but voltage fluctuations worsen due to load steps
Solution Approach 1:
The system maintains continuous power consumption through keephot instructions executed between mission cycles. This continuous action prevents the idle-to-active transitions that cause voltage fluctuations, while the keephot computations remain useful by maintaining processor warmth and readiness for subsequent mission cycles.
