    Abstract: Current tasks being executed in a set of modules of a signal processing system managed via an interface block are aborted so as to permit the execution of new tasks by pipelining eliminating transactions of said current tasks and executing transactions of the new tasks. Upon arrival of a signal to abort the current tasks, data and/or memory accesses present in said interface block are discarded.

    Abstract: A microcontroller includes an input pin and internal pull-up and pull-down circuits. External pull-up and pull-down circuits are also coupled to the input pin. The microcontroller is operable according to different configuration modes which include configuring the input pin in a floating state. A control logic then configures the internal pull-up and pull-down circuits according to an internal pull-up mode to acquire a first input voltage signal (at a first logic value) from the input pin, and further configure the internal pull-up and pull-down circuits according to an internal pull-down mode to acquire a second input voltage signal (at a second logic value) from the input pin. A selection of the operating mode of the MCU is then made based on the acquired first and second logic values.

    Abstract: A method for power management in an electronic circuit that comprises a processing system and an RF embedded circuit includes: generating a first regulated voltage with a power regulation module of the RF embedded circuit; generating a second regulated voltage from the first regulated voltage with a first linear regulator of the processing system; and controlling the power regulation module of the RF embedded circuit to operate according to a plurality of operation modes. The operation modes include: a first sleep mode in which a switched-mode power supply of the RF embedded circuit is off and a second linear regulator of the RF embedded circuit is off; a second sleep mode in which a switched-mode power supply is off and the second linear regulator is on; and a third sleep mode in which the switched-mode power supply is on and the second linear regulator is off.

    Abstract: In accordance with an embodiment, a system includes an oscillator equipped circuit having an oscillator control circuit configured to be coupled to an external oscillator and a processing unit comprising a clock controller. The clock controller includes an interface circuit configured to exchange handshake signals with the oscillator control circuit, a security circuit configured to receive the external oscillator clock signal and configured to select the external oscillator clock signal as the system clock, and a detection block configured to detect a failure in the external oscillator clock signal. Upon detection of the failure, a different clock signal is selected as the system clock and the interface circuit to interrupts a propagation of the external oscillator.

    Abstract: A digital processor, such as, e.g., a divider in a PID controller, performs a mathematical operation such as division (or multiplication) involving operands represented by strings of bit signals and an operator to produce an operation result. The processor is configured by identifying first and second power-of-two approximating values of the operator as the nearest lower and nearest higher power-of-two values to the operator. The operation is performed on the input operands by means of the first and second power-of-two approximating values of the operator by shifting the bit signals in the operands by using the first and second power-of-two approximating values in an alternated sequence to produce: first approximate results by using the first power-of-two approximating value, second approximate results by using the second power-of-two approximating value. The average of the first and second approximate results is representative of the accurate result of the operation.
