摘要： 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.

摘要： System on a chip, comprising several master pieces of equipment, several slave resources, an interconnection circuit coupled between the master pieces of equipment and the slave resources and capable of routing transactions between master pieces of equipment and slave resources. A first particular slave resource cooperates with an element of the system on a chip, for example a clock signal generator, and the element has the same access rights as those of the corresponding first particular slave resource.

摘要： The method for managing access rights of memory regions of a memory comprises assigning an execution permission status for each memory region in a firewall device dedicated to the memory, so that the content of a memory region having an executable status is capable of being executed by a processor, and the content of a memory region having a non-executable status cannot be executed by the processor.

摘要： The method for resetting a master device, configured to initiate transactions on a bus of a system on a chip, includes monitoring a completed or not state of the transactions initiated by the master device. In the case of reception of a command to reset the master device, the method includes a transmission of an effective reset command to the master device when the transactions initiated by the master device are in the completed state.

摘要： System on a chip, comprising several master pieces of equipment, several slave resources, an interconnection circuit capable of routing transactions between master pieces of equipment and slave resources, and a processing unit at least configured to allow a user of the system on a chip to implement within the system on a chip at least one configuration diagram of this system defined by a set of configuration pieces of information including at least one piece of identification information assigned to each master piece of equipment, The identification pieces of information are intended to be attached to all the transactions emitted by the corresponding master pieces of equipment, the set of configuration pieces of information not being used for addressing the slave resources receiving the transactions and being used to define an assignment of at least one piece of master equipment to at least some of the slave resources.

摘要： A method executes instructions, each corresponding to switching a signal, a delay, and a condition selected among first, second, or third conditions. Each execution includes performing, after the delay, switching the signal if the condition is the first condition, if the condition is the second condition and a flag is in an active state, or if the condition is the third condition and the flag is in an inactive state, or not switching the signal if the condition is the second condition and the flag is in the inactive state, or if the condition is the third condition and the flag is in the active state. A first instruction represents a first switching of a first signal, a first delay, and the second condition, and is immediately followed by a second instruction representing the first switching of the first signal, a second delay, and the third condition.

摘要： The present disclosure relates to a method for booting a processing device, the method including: generating, by a monotonic counter and during a first boot phase, a first count value; transmitting, by the monotonic counter, the first count value to an access control circuit of a memory; reading, on the basis of the first count value, first data stored in the memory; and generating, by the monotonic counter and during a second boot phase, a second count value greater than the first count value. The access control circuit of the memory is configured so that the reading of the first data is not authorized on the basis of the second count value.

摘要： In an embodiment a method for generating a random number includes selecting, by a first object, first symbols from an entropy pool of the first object, wherein the first object is an object of a group of mutually connected objects which are substantially identical, and wherein the entropy pool is fed with second symbols by objects of the group of mutually connected objects, applying, by the first object, a hash function to the first symbols to generate a random seed and generating, by the first object, the random number from the random seed.
