Abstract

The invention provides a calculation board system voltage stable control apparatus. The calculation board system voltage stable control apparatus comprises a field programmable gate array unit, a CPU and a calculation chip voltage stable control apparatus. The calculation chip voltage stable control apparatus comprises an impedance control unit, a voltage control unit, a first communication module and a second communication module, wherein the impedance control unit comprises an impedance detection module, an impedance switching module and an MCU; the impedance detection module detects calculation chips or the voltage control unit detects working states of the calculation chips; the MCU compares detected detection values with a preset value, and if the detection values are greater than the preset value, the MCU sends an impedance switching signal to enable the impedance switching module to perform impedance switching of the calculation chips; the two communication modules are used for reporting the working states of the calculation chips to the CPU through the field programmable gate array unit; and the CPU adjusts a preset impedance value and/or a preset voltage value according to the working states of the calculation chips. The invention aims to solve the problem of impedance or voltage inconsistency of the calculation chips.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a computing power chip voltage stabilization control device and a computing power board system voltage stabilization control device. Background technique [0002] When designing the hash board, since the current of each set of hash chips is very large, a large number of sets are required. Therefore, the power supply of each set of hash chips is cascaded through series voltage division. However, due to the inconsistent leakage current of each wafer of the produced computing chip, the impedance of each chip is inconsistent, and the power supply voltage is inconsistent. This will make the system may not be able to read the data and ID of the computing chip during the computing process, resulting in The data of the hash chip is lost, and the data results of the entire hash board are inaccurate. Therefore, it is necessary to keep the voltage of each computing power chip stable a...
