  • Patent number: 11144678
    Abstract: An integrated circuit includes one or more intellectual property (IP) cores, one or more general purposes input/output (GPIO) interfaces, each GPIO interface having one or more ports, and one or more security circuits, each security circuit being coupled between an IP core and a GPIO interface. A security circuit, in operation, selectively enables communications between the IP core and the GPIO interface coupled to the security circuit based on an indication of the security status of the IP core, an indication of the security status of the GPIO interface or both the indication of the security status of the IP core and the indication of the security status of the GPIO interface.

  • Patent number: 10891399
    Abstract: A system includes an intellectual property circuit; a general purpose input/output circuit coupled to the intellectual property circuit via a data path; and a switch coupled to the data path. The switch is activatable via a switch enable signal propagated on a switch enable path having a first end coupled to the intellectual property circuit and a second end coupled to the general purpose input/output circuit. The system further includes a secure link circuit coupled between the intellectual property circuit and the general purpose input/output circuit along the switch enable path. The secure link circuit is sensitive to security statuses of the intellectual property circuit and the general purpose input/output circuit, the secure link circuit being configured to admit propagation of the switch enable signal on the switch enable path in response to the intellectual property circuit and the general purpose input/output circuit having identical security statuses.

  • Patent number: 10788870
    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.

  • Patent number: 10236066
    Abstract: 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.

  • Patent number: 9823965
    Abstract: A method includes: writing first data in a first partition of a first memory module and second data in a first partition of a second memory module, and selectively operating the first and second memory modules in a first operating mode and a second operating mode. The first operating mode includes writing parity bits for the first data in a second partition of the second memory module and parity bits for the second data in a second partition of the first memory module. The second operating mode includes writing further data instead of parity bits in the second partition of one or both the first memory module and the second memory module.

  • Patent number: 7626438
    Abstract: An embodiment of a circuit switches between at least a first clock signal and a second clock signal in response to a corresponding switch command, and includes a selection module to select at a switch instant said second clock signal under the control of a signal selector. The circuit comprises a logic-based filter module located downstream of said selection module and configured to produce an outgoing clock signal filtered under the control of a filter signal and also includes a control module configured to receive said switch command and to send said select signal to said selection module delaying said switch instant by a first interval of time, said control module also being configured to send said active filter signal to said filter module in a second interval of time that comprises an edge of the first clock signal and an edge of the second clock signal.

  • Patent number: 7593358
    Abstract: Transmitter device including a modulator apparatus for the generation of a modulated digital signal in a remote control system. The modulated signal is defined by at least one characteristic quantity correlated to an information to transmit. The modulator apparatus is characterized by including a finite states machine for generating a modulating digital signal to combine with a carrier signal and obtain the modulated signal. The finite states machine generates the modulating signal on the basis of digital data corresponding to said at least one characteristic quantity.
