Abstract

The invention discloses an energy-saving device applied to an analog to digital converter. The device comprises a many-to-one multitask device for receiving pulse wave signals. The many-to-one multitask device is connected with the analog to digital converter. The analog to digital converter is connected with a data compression module. The analog to digital converter converts the pulse signals transmitted by the many-to-one multitask device into analog to digital signals. The data compression module predicts the analog to digital signals, controls the pulse wave signals input by the many-to-one multitask device according to the prediction results, or recodes the prediction results so as to reduce the data quantity and then outputs the coded serial code. The operation energy consumption of the analog to digital converter is reduced; moreover, the transmitting energy consumption demanded when the signals are transmitted to the processor for processing is reduced; the problem of high energy consumption in the wireless transmission process is reduced; the demand of the modern portable electronic product is satisfied; and the usage time of the electronic device with the set electric quantity is prolonged.

Description

technical field [0001] The invention belongs to the field of digital signal processing, and relates to an analog-to-digital converter device, in particular to an energy-saving device applied to the analog-to-digital converter. Background technique [0002] Today's smart device market is very considerable, such as mobile phones and watches contain a large number of sensors to provide services for users. The signal received by the sensor is an analog signal in nature. When doing higher-order signal calculation or processing, an analog-to-digital converter must be used to process it in the form of a digital signal. [0003] At this stage, the control of the analog-to-digital converter is done by the MCU with the Sensorhub function, but there is no relevant module to solve the problem of energy loss during control. However, in portable devices such as mobile phones, power consumption has always been the most important indicator in the design of electronic components. In analog...
