The critical locking state represents the working core voltage used by the digital signal processor at the current working temperature, and can meet the lowest voltage when the optical transceiver system works, namely the lowest power consumption state when the optical transceiver system meets the performance index requirement.
The adaptive voltage regulator outputs a core voltage V to the digital signal processor according to the regulation instructionAVSAnd adjusting to enable the working core voltage of the digital signal processor to enable the digital signal processor to work in a critical locking state, so that the optical transceiver system uses the lowest voltage when meeting the requirement of the working performance index, the lowest power consumption state is achieved, and the power consumption is saved.
Furthermore, the performance monitor can also acquire the working temperature of the digital signal processor, wherein the working temperature is the current working environment temperature of the system, is not controlled by the system, and feeds the acquired working temperature back to the power controller. The power controller judges whether the working core voltage of the digital signal processor at the working temperature can enable the digital signal processor to work in a critical locking state or not, and obtains a regulating instruction.

The adjustment instructions include decreasing, increasing, and not changing the voltage provided to the digital signal processor.
Step S200: and adjusting the core voltage provided for the digital signal processor according to the adjusting instruction issued by the digital signal processor, so that the digital signal processor works in a critical locking state.
If the adjusting instruction received by the self-adaptive voltage regulator is to reduce the working core voltage of the digital signal processor, the current working core voltage of the digital signal processor is higher than the working voltage for enabling the digital signal processor to work in a critical state, and then the core voltage provided for the digital signal processor is reduced according to the adjusting instruction issued by the power regulator.
If the adjusting instruction received by the self-adaptive voltage regulator is to increase the working core voltage of the digital signal processor, the current working core voltage of the digital signal processor is lower than the working voltage which enables the digital signal processor to work in a critical state, and then the core voltage provided for the digital signal processor is increased according to the adjusting instruction issued by the power regulator.
