  • SYSTEM AND METHOD FOR MULTI-CORE ACCESS CONTROL ON A DUAL-CORE MICROCONTROLLER
    Publication number: 20250328483
    Abstract: A method includes powering up a privileged core while leaving an unprivileged core unpowered, the privileged core and the unprivileged core respectively of a microcontroller, configuring a hardware-based mechanism of access control for the unprivileged core, the configuring at least partially based on control parameters that define access to resources by the unprivileged core; and powering up the unprivileged core, operation of the unprivileged core subject to the hardware-based mechanism of access control.

  • Two-wire serial interface and protocol
    Patent number: 9910819
    Abstract: In a serial transmission method using a two-wire serial interface, a master device transmits a first synchronous serial signal via the two-wire serial interface to wake-up a slave device followed by an asynchronous data transmission on one of the two-wires of the two-wire serial interface. The asynchronous data signal directly controls a function of the slave device.
