Hash Board Frequency Sweeping for Temperature-Balanced Chip Domains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hash boards face issues of resource waste and imbalanced performance due to uniform frequency operation across chips, which is influenced by varying temperatures from the air inlet to the air outlet.
Innovation Solution
A frequency sweeping method that adjusts chip operating frequencies to exhibit a descending linear relationship, starting with an initial voltage application, followed by voltage regulation to determine a limit voltage, and then frequency adjustment to ensure the chip domain at the air inlet has the lowest frequency and the chip domain at the air outlet has the highest frequency, maintaining an average operating frequency equal to the target frequency.

Engineering Contradiction Analysis
1Ease of operation
If all chips operate at the same frequency, then the system is simple to control, but resource waste and imbalanced performance occur due to temperature variations
Solution Approach 1:
The patent applies local quality by assigning different operating frequencies to different chip domains based on their temperature conditions. Specifically, chip domains are divided into multiple frequency groups, where each group operates at a different frequency level. This allows chips in hotter regions to run at lower frequencies while chips in cooler regions operate at higher frequencies, optimizing overall system performance while maintaining manageable control complexity through automated frequency grouping.
2Power
If frequency is increased to improve processing speed, then computational power increases, but temperature rises causing performance degradation
Solution Approach 1:
The patent implements dynamics by making the operating frequency of different chip domains variable rather than fixed. The system dynamically adjusts frequencies based on real-time temperature monitoring, creating a dynamic frequency allocation strategy where higher frequencies are assigned to cooler chip domains and lower frequencies to hotter domains. This dynamic adaptation allows the system to maximize computing power while managing temperature effects.
3Use of energy by stationary object
If voltage is reduced to lower temperature, then energy consumption decreases, but computing speed is reduced
Solution Approach 1:
The patent applies segmentation by dividing the chip domain into multiple frequency groups based on temperature conditions. Instead of uniformly reducing voltage across all chips, the system segments the chip domain and applies different frequency-voltage combinations to different segments. This allows energy-efficient operation in hotter regions while maintaining high performance in cooler regions, optimizing the trade-off between energy consumption and computing speed.

AI summary
A frequency sweeping method for a hash board includes: applying an initial voltage to the hash board to power on the hash board, and controlling chips in all chip domains to operate at a target frequency; switching each of the chips to a SPAT mode while maintaining the chip at the target frequency, and progressively reducing a voltage of the hash board; calculating a nonce response rate of the chip; and in a case where the nonce response rate of the chip is less than a predetermined threshold, determining a previous voltage level corresponding to the nonce response rate as a limit voltage of the hash board under the target frequency; maintaining each of the chips at the limit voltage, and calculating a frequency adjustment function of the hash board.
