Abstract: A method and apparatus for performing dynamic current scaling of an input current of a voltage regulator are provided. The method and apparatus allow tuning current consumption in various applications, calculating a duration of an activity phase in which various algorithms are executed and activating dynamic current scaling of a regulator if the activity duration is shorter than a programmable threshold. A controller receives a threshold for an activity duration and a window size in which to evaluate the activity duration.

Abstract: The present disclosure is directed to a device and method for generating and transmitting a TDM signal including both raw data and processed data. The device includes a sensor having a time division multiplexing (TDM) interface. The TDM interface transmits both raw data and processed data in a single TDM signal by reserving one or more slots inside a TDM frame for transmission of the processed data. The sensor also embeds additional information inside a data stream of raw data by repurposing one or more of values of the raw data as an exception code, flag, or another type of notification. The device is also enabled to transmit data, and disabled when not in use in order to conserve power.

Abstract: A programmable data processing circuit is configured for receiving sensor signals indicative of gestures for identification by the processing circuit. The processing circuit applies to the sensor signals finite state machine processing resources to provide identification output signals indicative of gestures identified as a function of the sensor signals. A plurality of finite state machine processing programs loaded into the processing circuit include a data section and an instruction section. The data section including a fixed size part specifying respective processing resources used by the programs in the plurality of finite state machine processing programs and a variable size part with respective sizes for allocating the respective processing resources used by the programs in the plurality of finite state machine processing programs. The instruction section including conditions and commands for execution by the respective processing resources used by the programs by operating on data located in the respective data sections.
