Data processing method, and relevant devices

摘要

A data processing method, a data processing system, and relevant devices are provided, which are used to reduce system power consumption. The method in embodiments of the present invention includes: performing sampling on an analog signal to obtain an analog sample value; performing analog-to-digital conversion on the analog sample value to obtain a digital signal; dividing bits forming the digital signal into at least two bit groups; and turning off output of bits in at least one bit group if a preset turnoff condition is satisfied. A data processing system and relevant devices are further provided.

1. A data processing method, comprising:
receiving, by an analog to digital converter (ADC), an analog signal through an input port; performing, by the ADC, sampling on the analog signal to obtain an analog sample value; performing, by the ADC, analog-to-digital conversion on the analog sample value to obtain a digital signal; dividing, by the ADC, bits forming the digital signal into at least two bit groups based on importance weights of each bit; turning off, by the ADC, output of bits in at least one bit group with a lower importance weight when a preset turnoff condition is satisfied; and outputting, by the ADC, bits which are not turned off if there are any through an output port.
