    Abstract: Dynamic power control embodiments concern a data processing pipeline. First and second pipeline stages respectively receive first and second clock signals. The first and second pipeline stages are configured to perform first and second operations respectively triggered by first timing edges of the first clock signal and second timing edges of the second clock signal. A clock controller is configured to generate the first and second clock signals. The clock controller is capable of operating in a first mode in which, during a first data processing cycle of the data processing pipeline, a first of the first timing edges is in-phase with a first of the second timing edges. The clock controller is also capable of operating in a second mode in which, during a second data processing cycle of the data processing pipeline, a second of the first timing edges is out of phase with a second of the second timing edges.

    Abstract: A diode control device include a first terminal for receiving a first power supply voltage and a second terminal for receiving a second power supply voltage. A circuit of the diode control device applies a regulated voltage on the anode of the diode in response to a control voltage. The control voltage is equal to a preset voltage when a reference voltage is less than or equal to zero. Conversely, when the reference voltage is greater than zero, the control voltage is equal to the sum of the present voltage and a difference between cathode voltage of the diode and the reference voltage.

    Abstract: A charge-pump device receives two complementary driving signals and a DC signal that are applied to a charge-pump stage containing a full-wave rectifier bridge configured to deliver a DC output signal. The bridge includes active switches controllable by control signals present at two control nodes. The charge-pump device further receives complementary auxiliary signals that are respectively synchronous with the complementary driving signals but have faster edges. Two resistive capacitive filters filter the complementary auxiliary signals to generate control signals at the two control nodes for controlling actuation of the active switches in the bridge.

    Abstract: A level-shifter circuit receives one or more input signals in an input level domain and includes provides at an output node an output signal in an output level domain shifted with respect to the input level domain. The circuit includes output circuitry including a first drive node and a second drive node that receive first and second logical signals so that the output signal has a first output level or a second output level in the output level domain as a function of at least one of the first and second logical signals. The circuit includes first and second shift capacitors coupled to the first and second drive nodes as well as capacitor refresh circuitry.

    Abstract: A digital signal processor includes K first electronic circuits. The first inputs receive K groups of G successive coefficients of a polynomial. The polynomial are of degree N with N+1 coefficients, where K is a sub-multiple of N+1 greater than or equal to two and G is equal to (N+1)/K. The first electronic circuits are configured to simultaneously implement K respective Horner methods and deliver K output results. A second electronic circuit includes a first input configured to successively receive the output results of the first electronic circuits starting with the output result of the first electronic circuit having processed the highest rank coefficient of the coefficients. A second input is configured to receive a variable X and the second electronic circuit is configured to implement a Horner method and deliver a value of the polynomial for the variable X on the output of the second electronic circuit.
