Low-power context-aware control for analog frontend
First Claim
1. A method for operating an analog frontend (AFE), comprising:
- selecting one of multiple sensors coupled to the AFE;
receiving input sensor data from the sensor;
computing features for the sensor based on the input sensor data, the features representing selected operating condition information of the AFE for the sensor;
determining one of multiple discrete operating states of the AFE for the sensor based on the computed features; and
dynamically adjusting operation of the AFE to interface with the sensor based on the determined operating state, including controlling a configuration of the AFE that controls how the AFE receives the input sensor data from the sensor.

Abstract
An analog frontend (AFE) interface is dynamically programmable based on a determined operating state. The AFE includes hardware to interface with multiple different sensors. The AFE includes analog processing hardware that can select input data from one of the multiple sensors. The analog processing hardware is coupled to a processor that computes features from the sensor, where the features represent selected operating condition information of the AFE for the sensor. The processor is to determine one of multiple discrete operating states of the AFE for the sensor based on the computed features and dynamically adjust operation of the AFE to interface with the sensor based on the determined operating state. Dynamically adjusting the operation of the AFE includes controlling a configuration of the AFE that controls how the AFE receives the input sensor data from the sensor.
