摘要： A power-saving system includes a retention memory element for a retained peripheral that is set to a logic state during an operational-power mode and maintains the logic state during an enhanced power-saving mode. The power-saving system also includes a non-retention memory element for a non-retained peripheral that is set to a logic state during the operational-power mode of the power-saving system; and a controller that instructs the retention memory element to maintain its logic state while in an enhanced power-saving mode.

摘要： 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. When the memory contains the predetermined amount of data, the communication interface starts transmission of the data stored in the memory. Alternatively, when 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.

摘要： A non-volatile data memory space for a range of user addresses is provided by means of a range of non-volatile flash memory locations for writing data. The range of flash memory locations for writing data is larger (e.g., 4 KB v. 100 B) than the range of user addresses. Data for a same user address may thus be written in different flash memory locations in a range of flash memory locations with data storage endurance correspondingly improved.

摘要： A system, such as a System-on-Chip includes an interface component or PLUG which generates transactions over an IP block, such as an interconnect serving one or more clients via virtual channels. The client or clients are mapped onto the virtual channels via client/virtual channel mappings. The virtual channels are provided as a first set of virtual channels in the interface component which cooperate with a second set of virtual channels in the IP block. First and second client/virtual channel mappings for the first set of virtual channels and the second set of virtual channels are provided. The first and second client/virtual channel mappings are separately programmable and mutually decoupled from one another.

摘要： A clock generator includes a microcontroller unit calibrated by aligning at subsequent calibration times a frequency of a first clock with respect to the frequency of a second clock having a higher frequency accuracy than the first clock, with the frequency of the first clock varying between subsequent calibration times. The frequency of the first clock is aligned to a frequency which is offset by a certain amount with respect to the frequency of the second clock to counter frequency error which may accumulate over time due to the variation in the frequency of the first clock.

摘要： A method of interfacing an LC sensor with a control unit is described. The control unit may include first and second contacts, and the LC sensor may be connected between the first and second contacts. The method may include starting the oscillation of the LC sensor, and monitoring the voltage at the second contact, in which the voltage at the second contact corresponds to the sum of the voltage at the first contact and the voltage at the LC sensor. The voltage at the first contact may be varied such that the voltage at the second contact does not exceed an upper voltage threshold and does not fall below a lower voltage threshold.

摘要： 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.
