Abstract: A module incorporated within a system-on-a-chip operating in a steady-state power supply phase is powered by supplying to the module a regulated power supply voltage obtained from a feedback control loop. The receives a main power supply voltage and a negative feedback voltage. The negative feedback voltage is generated inside the system-on-a-chip starting from an effective supply voltage of the module and from a setpoint signal corresponding to a desired regulated power supply voltage.

Abstract: A voltage regulator includes a pre-regulation circuit and a low drop-out voltage regulator. The pre-regulation circuit is configured to generate a first power supply voltage based on an input voltage. The low drop-out voltage regulator is configured to generate a second power supply voltage based on the first power supply voltage. Additionally, the low drop-out voltage regulator is configured to filter a low-frequency component of the first power supply voltage.

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 system includes a processing unit, a memory configured to store at least one first group of instructions and one second group of instructions for execution by the processing unit, the processing unit being configured to sequentially extract from the memory instructions of the first group and instructions of the second group for their execution. The system also includes a controller including a first auxiliary memory configured to store a protection criterion, a comparator configured to compare the storage address of each extracted instruction with the protection criterion, and a control circuit configured to, in response to the storage address meeting the protection criterion, trigger a protection mechanism including at least one prohibition for the processing unit to execute again at least one portion of the instructions of the first group, during the execution of the instructions of the second group.

Abstract: A system includes inertial sensors and a GPS. The system generates a first estimated vehicle velocity based on motion data and positioning data, generates a second estimated vehicle velocity based on the processed motion data and the first estimated vehicle velocity, and generates fused datasets indicative of position, velocity and attitude of a vehicle based on the processed motion data, the positioning data and the second estimated vehicle velocity. The generating the second estimated vehicle velocity includes: filtering the motion data, transforming the filtered motion data in a frequency domain based on the first estimated vehicle velocity, generating spectral power density signals, generating an estimated wheel angular frequency and an estimated wheel size based on the spectral power density signals, and generating the second estimated vehicle velocity as a function of the estimated wheel angular frequency and the estimated wheel size.

Abstract: According to one aspect, a method for compiling by a compilation tool a source code into a computer-executable code comprises receiving the source code as input of the compilation tool, translating the source code into an object code comprising machine instructions executable by a processor, then introducing, between machine instructions of the object code, additional instructions selected from illegal instructions and no-operation instructions so as to obtain the executable code, then delivering the executable code as output of the compilation tool.
