1. A power consumption control circuit, for controlling a power consumption of a to-be-controlled circuit, wherein the power consumption control circuit comprises:
a data serial-to-parallel module, a data counting module, a data latch control module, and a power consumption mode determination module;
wherein the data serial-to-parallel module receives serial input data from the to-be-controlled circuit, converts the serial input data into parallel data, and sequentially outputs least significant bits of the parallel data, wherein the to-be-controlled circuit controls a downstream circuit based on the serial input data;
wherein the data counting module receives the serial input data and counts a quantity of valid data bits of the serial input data, generating a valid flag bit when the quantity of valid data bits reaches a preset value;
wherein the data latch control module generates a valid latch pulse after the to-be-controlled circuit completes reception and transmission of data; and
wherein the power consumption mode determination module is connected to output terminals of the data serial-to-parallel module, the data counting module, and the data latch control module, wherein the power consumption mode determination module receives the serial input data and a power-on reset signal of the to-be-controlled circuit, and generates a power consumption control signal for the to-be-controlled circuit; and wherein the to-be-controlled circuit enters a working mode when valid data is received and it is necessary to control the downstream circuit; otherwise, the to-be-controlled circuit enters a power-saving mode.
