Abstract: A sensor chip is mounted on a PCB and electrically connected to a SOC mounted on the PCB via at least one conductive trace. The sensor chip includes configuration registers storing and outputting configuration data, and a PLD receiving digital data. The PLD performs an extraction of features of the digital data in accordance with the configuration data, and the configuration data includes changeable parameters of the extraction. A classification unit processes the extracted features of the digital data so as to generate a context of an electronic device into which the sensor chip is incorporated relative to its surroundings, the processing being performed in using a processing technique operating in accordance with the configuration data. The configuration data also includes changeable parameters of the processing technique. The classification unit outputs the context to data registers for storage.
