Power control system and method for heterogeneious computing, device, and non-transitory readable storage medium

A power control method for heterogeneous computing, comprising:

• taking a functional module of a heterogeneous computing unit that sends an access request as a first functional module, and taking a functional module of the heterogeneous computing unit that is requested as a second functional module;
• outputting, by a phase locked loop, a clock frequency corresponding to each functional module in the heterogeneous computing unit on a one-to-one basis;
• connecting a handshake detection unit to the heterogeneous computing unit via an access bus, detecting, by the handshake detection unit, an access request answer sent by the first functional module and a response request answer sent by the second functional module, and generating, according to the access request answer and the response request answer, status flags for the first functional module and the second functional module, respectively, and outputting same;
• and
• outputting, by a frequency-controlled voltage source, one path of voltage bus for each functional module, connecting each path of voltage bus to a power pin of a corresponding functional module and connecting in series a first switch transistor therebetween, controlling, by the frequency-controlled voltage source according to the status flags of the first functional module and the second functional module, a corresponding first switch transistor to be turned on or off, and adjusting, according to the clock frequency, a voltage value of a corresponding voltage bus when the first switch transistor is turned on.
