Abstract: A method of detecting network anomalies includes the reception, via an interface of an electronic device, of a first stream of packets sent by a source that is external and/or the transmission of a first stream of packets to a destination external; the computation, by a processing circuit, of a first packet stream identifier based on at least one of: a packet source address of the packets of the first stream; and a packet destination address of the first stream; searching, in an ordered dynamic data structure stored in a memory and including a plurality of entries. The searching is performed based on the value of the first packet stream identifier with respect to one or more search threshold values; and based on metadata associated with the first entry, blocking reception of the first stream of packets.

Abstract: In one embodiment, a system on chip includes a dynamic voltage and frequency scaling (DVFS) power supply, a secure environment, a non-secure environment, and a power supply management control module. The secure environment is configured to generate a secure instruction defining a permitted operating point of voltage and frequency for the DVFS power supply. The non-secure environment is configured to generate a request to modify the DVFS power supply, where the request to modify includes a voltage-frequency operating point. The power supply management control module is configured to scale the DVFS power supply to the permitted operating point, in response to the request to modify the DVFS power supply.

Abstract: The data processing device comprising at least two processing units, each processing unit (CR1, CR2) being alternately in a first operating mode and in a second operating mode, each processing unit switching to its second operating mode at the end of a transient phase (PHT1, PHT2) comprising at least one activation of resources common to these two processing units; at least one of the two units is configured to switch at least once to its second operating mode with a temporal flexibility, and the instant of switching to its second operating mode, of the processing unit or units exhibiting the said flexibility, is adjusted in such a way that the two units are in their second operating mode after the said common resources have been activated once (26) in the course of the two respective transient phases, if this temporal adjustment is compatible with the said temporal flexibility.

Abstract: A method of driving a mobile communication terminal in a cellular network, includes monitoring with a control unit of the mobile communications terminal, reception power levels between the mobile communication terminal and cellular network base stations at a predefined monitoring rate for each base station. Timing information values for a number of base stations are intermittently monitored by the control unit. Drift of the timing information values for at least two of the base stations is monitored and significant motion of the mobile communication terminal is deemed detected if at least one of the timing information values indicates a drift equal to or exceeding a given timing drift threshold. The predefined reception power level monitoring rate is reduced to a reduced reception power level monitoring rate for at least a number of the base stations as long as the motion of the mobile communication terminal is not significant.
