    Abstract: In an embodiment a method includes detecting, by a monitoring circuit, on a bus of a device during execution by a processor of a code stored in a memory, an address for reading from the memory, wherein the device comprises the processor, the memory, the monitory circuit and the bus coupled to the memory, comparing, by the monitoring circuit, the address with one or more first addresses and controlling, by the monitoring circuit, a clock control circuit to prevent an activation of one or more peripheral circuits when the address is part of the one or more first addresses.

    Abstract: System, method, and circuitry for generating content for a programmable computing device based on user-selected configuration information. A settings registry is generated based on the user's selections. The settings registry and the user selected configuration information is utilized to generate the content, such as code, data, parameters, settings, etc. When the content is provided to the programmable computing device, the content initializes, configures, or controls one or more software and hardware aspects of the programmable computing device, such as boot sequence configurations, internal peripheral configurations, states of the programmable computing device, transitions between states of the programmable computing device, etc., and various combinations thereof.

    Abstract: A method includes receiving, by a first microprocessor, a request of modification of a content of a first memory of the first microprocessor, the first memory being accessible only by the first microprocessor. The method includes accessing, by the first microprocessor, first data associated with the request and a signature generated from the first data with an asymmetric cipher algorithm. The first data and the signature are available in a second memory of a second microprocessor, and the first data is representative of a modification to be applied to the content of the first memory. The modification is representative of a modification of a set of services exposed by the first microprocessor. The method includes verifying, by the first microprocessor, authenticity of the first data based on the signature; and modifying the content of the first memory according to the first data, the modifying being conditioned by the verifying.
