Abstract: According to one exemplary embodiment, a data processing device is described, having a plurality of data processing components which are configured to exchange respective synchronization information with one another in pairs at predefined synchronization points, and having a writable configuration memory configured to store, for each reset type of a plurality of reset types, whether the exchange of the respective synchronization information is required for all of the synchronization points, in order that the respective pair of data processing components may continue its processing beyond the synchronization points. The data processing components are configured to continue or not continue their processing beyond synchronization points in accordance with the content of the writable configuration memory in the absence of an exchange of synchronization information.

Abstract: Systems, methods, and circuitries are provided for enabling in-field re-marking of micro controllers. In one example, a micro-controller unit (MCU), includes one or more processors; non-reprogrammable memory, reprogrammable memory, and marking circuitry. The non-reprogrammable memory is configured to store an umbrella license file defining a first set of MCU functions or MCU resources that are enabled for execution or access by the one or more processors and a second set of MCU functions or MCU resources that are permanently disabled for execution or access by the one or more processors. The reprogrammable memory is configured to store an actual license file defining a third set of MCU functions or MCU resources that are licensed for execution or access by the one or more processors. The marking circuitry configured to control access to the MCU functions and MCU resources based on the umbrella license file and the actual license file.
