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 communication interface couples a transmission circuit with an interconnection network. The transmission circuit requests transmission of a predetermined amount of data. The communication interface receives data segments from the transmission circuit, stores the data segments in a memory, and verifies whether the memory contains the predetermined amount of data. In the case where the memory contains the predetermined amount of data, the communication interface starts transmission of the data stored in the memory. Alternatively, in the case where the memory contains an amount of data less than the predetermined amount of data, the communication interface determines a parameter that identifies the time that has elapsed since the transmission request or the first datum was received from the aforesaid transmission circuit, and verifies whether the time elapsed exceeds a time threshold. In the case where the time elapsed exceeds the time threshold, the communication interface starts transmission of the data stored in the memory.

Abstract: A communication system for interfacing a transmitting circuit with a receiving circuit includes a transmission interface for receiving data from the transmitting circuit and transmitting the data received over at least one data line in response to a transmission clock signal. The communication system also includes a reception interface configured for receiving the data in response to a reception clock signal and transmitting the data received to the receiving circuit. In particular, the system is configured for generating a plurality of clock signals that have the same frequency but are phase-shifted with respect to one another. In addition, during a calibration phase, the system is configured for selecting one of the clock signals for the transmission clock signal or reception clock signal via selecting at least one of the clock signals for transmission of test signals via the transmission interface and verifying whether the test signals received via the reception interface are correct. The system is further configured to use, during normal operation, the clock signal selected during the calibration phase for transmission of data.

Abstract: A voltage regulator coupled between a first node and second node includes a first (full-power) regulator circuit and a second (low-power) regulator circuit. In a first mode: the first regulator circuit is activated (with the second regulator circuit inactive) when the voltage at the first node is a battery voltage, and the voltage regulator is kept de-activated when the voltage at the first node is a ground voltage. In a second mode: the first regulator circuitry in is active (with the second regulator circuitry inactive) when the voltage at the first node is a battery voltage, and the voltage regulator is inactive when the voltage at the first node is a ground voltage. In a third mode: the second regulator circuitry is active (with the first regulator circuitry inactive) irrespective of the voltage at the first node being at the battery voltage or the ground voltage.

Abstract: A circuit includes a first node configured to receive a reset signal. A reset drive stage drives a reset node. The reset drive stage is coupled to the first node via a reset signal path to propagate the reset signal to the reset drive stage. The reset drive stage is activated as a result of assertion of a reset actuation state of the reset signal. A sensing node is coupled to the reset node via a signal sensing path. The sensing node is sensitive to a signal level of the reset node reaching a reset threshold. A reset signal hold circuit block is coupled to the first node and is configured to receive a reset command signal and assert the reset actuation state of the reset signal at the first node as a result of the reset command signal received.

Abstract: A method of interfacing a LC sensor with a control unit is provided. The control unit may include first and second contacts, where the LC sensor is connected between the first and the second contact. A capacitor is connected between the first contact and a ground. To start the oscillation of the LC sensor, the method may include during a first phase, connecting the first contact to a supply voltage and placing the second contact in a high impedance state such that the capacitor is charged through the supply voltage. During a second phase, the first contact may be placed in a high impedance state, and the second contact connected to the ground such that the capacitor transfers charge towards the LC sensor. During a third phase, the first contact and the second contact may be placed in a high impedance state so the LC sensor is able to oscillate.
