Abstract: Method for managing, in a receiver, a radio service continuity based on synchronized broadcasts of identical audio contents on different frequencies, comprising, the receiver being tuned to a first frequency corresponding to a first broadcast of a first audio content, a detection in the receiver of a second audio content broadcast on a second frequency, having a level of quality above a threshold and paired with the first audio content.

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 device includes a memory, a first firmware copy of the device stored in a first position of the memory and a second firmware copy of the device stored in a second position of the memory, where each of the first firmware copy and the second firmware copy includes instructions, when executed by the device, perform an operation of the device; and a first delta copy associated with the first firmware copy. The first delta copy includes instructions that differ from the first firmware copy when executed at the first position and are the same when executed at the second position. The device is configured to receive the first delta copy from an external system and store the first delta copy in the memory.

Abstract: System, method, and circuitry for generating content for a programmable computing device based on user-selected memory regions. Contiguous regions that share memory access attributes are merged, interleaved contiguous regions that share at least one nested attribute are defined into combined regions, and remaining regions are defined as separate independent regions. A memory protection unit (MPU) region size closest to a size of each defined region is identified. If the start address of each region aligns with the address structure of the MPU region size, then those regions are assigned to MPU regions having the MPU region size; otherwise, another MPU size that aligns with the size of the regions is selected and those regions are assigned to MPU regions having that size. Content is generated to configure settings of MPU regions of the programmable computing device for the merged contiguous regions, the combined region, and the independent regions.

Abstract: In embodiments, a system includes a first and a second processing unit, a memory, and a firewall device. The first processing unit operates in a secure mode and generates memory access requests having a secure level. The second processing unit operates in a non-secure mode and generates memory access requests having a non-secure level. The memory includes a first memory area that can be shared between the first and second processing units. The firewall device includes a first firewall circuit with a first configuration authorizing access to the first memory area in the presence of a secure or non-secure level access request. The firewall circuit includes a second configuration prohibiting access to the first memory area in the presence of a secure level access request and authorizing access to the first memory area only in the presence of a non-secure level access request.

Abstract: The present disclosure relates to a method for authenticating instructions and operands in an electronic system comprising a controller. The method includes extracting instructions and operands via a first circuit of the controller from at least a first memory internal to the controller using a matrix bus of the controller, collecting, on the matrix bus, via a second circuit internal to the controller, instructions and operands during their transmission to the first circuit, and generating a word representative of the instructions and operands.

Abstract: The present disclosure relates to a method for demodulating a RF signal comprising the steps of: detecting if an analog to digital converter (ADC) of a Near Zero Intermediate Frequency (NZIF) receiver is in a clipping state; and if yes: determining and storing a first value (RSSI1) representative of the energy of a received signal demodulated by the Near Zero Intermediate Frequency (NZIF) receiver using a first intermediate frequency (IF1); determining and storing a second value (RSSI2) representative of the energy of the received signal demodulated by the Near Zero Intermediate Frequency (NZIF) receiver using a second intermediate frequency (IF2) corresponding to the opposite value of the first intermediate frequency (IF1), selecting the intermediate frequency corresponding to the lowest value of said first and second values.
