    Abstract: A method for reading or writing data at an address of a memory is disclosed. The data includes a number of consecutive words that each has a plurality of bits. The words are transferred to or from the memory in synchronization with a clock signal so that each word is transferred in one cycle of the clock signal. The bits are scrambled or unscrambled by applying a logic function to the bits of each word. The logic function is identical for the scrambling and the unscrambling and makes use of a bit-key that is dedicated to the word and is identical for the scrambling and the unscrambling. Each bit-key comes from a pseudo-random series generated based on the address.

    Abstract: A stepper motor is driven according to step driving modes including a full-step driving mode, a half-step driving mode and micro-stepping modes. The stepper motor may also be driven in an acceleration phase. A method of controlling the stepper motor includes controlling the current step driving mode of the motor by a processing unit. During the acceleration phase of the stepper motor and the stepper motor being in driven in a current step driving mode other than the full-step driving mode, the processing unit tests, after each speed increase, if a remaining computing power of the processing unit is sufficient for control of the stepper motor to remain in the current step driving mode, and if not the processing unit, in presence of a first switching condition, switches control of the stepper motor to the driving mode having the closest coarser step.

    Abstract: Contactless power transfer from a transmitter to a receiver is managed. A magnetic field is generated by the transmitter from a command at a control frequency for a switching resonant circuit. The receiver communicates information to the transmitter through modulation of the magnetic field. The modulation is detected by the transmitter so as to extract the information. An adjustment of the control frequency is then made according to the received information. The modulation detection involves detecting variations in the control frequency.

    Abstract: A module incorporated within a system-on-a-chip operating in a steady-state power supply phase is powered by supplying to the module a regulated power supply voltage obtained from a feedback control loop. The receives a main power supply voltage and a negative feedback voltage. The negative feedback voltage is generated inside the system-on-a-chip starting from an effective supply voltage of the module and from a setpoint signal corresponding to a desired regulated power supply voltage.
