摘要： A method for detecting errors in a linear sequence of commands executed by a processor and stored in a memory at a predetermined start address, comprises the association of each word in the sequence to a bit of the start address. Before storing each sequence word into the memory, the method determines the value of an unused bit of the word so that the value of the associated bit of the start address will be equal to the result of a predetermined function applied to the bits of the word. When reading a sequence word in said memory, the method compares the result of said function applied to the bits of the word read, with the value of the associated bit of the start address, and transmits an error signal if a difference is detected.

摘要： A device for managing a plurality of independent queues in a common non-dedicated memory space uses a set of memory space resource use vectors with one vector per managed queue. A vector defines a list of free memory space locations. Read and write pointer registers store the address of memory locations last written or read and a circuit for evaluating the closest successor of these latter memory locations. The device has the advantage of enabling all memory resources to be used, the same resource being usable by any queue.

摘要： This switch comprises a central buffer memory (30) for temporarily storing the data traffic which it receives, the time for performing the routings and for carrying out the resendings of the messages that it receives. It is noteworthy in that its central buffer memory (30) and the accesses to this buffer memory (30) by its various input/output ports are managed by a sequencer (40) in such a way as to have an implicit measure of the timescale for storing the messages in the central buffer memory (30) and to minimize the number of switchings which generate consumption and electromagnetic disturbances. Advantageously, the buffer memory is embodied with the aid of several modules (A, B, C, D) operating in parallel.

摘要： The invention relates to the selection and sorting, by an installation having access to one or more packet transmission networks, of the packets relating to it, from among the entirety of the packets made available by the networks, given that the packets respect at least two layers of protocols or even more. It consists of a method of selecting and sorting that successively implements, in respect of searches for matching addresses, two directories of addresses, the first of so-called lower levels having as elements the various possible combinations of the values taken by the addressing information contained in the service information fields of the first two levels of protocols, the second so-called higher levels having as elements the addressing information contained in the service information fields of the protocols of levels higher than two, the elements of the first and second directories being linked by compatibility links targeting those that can simultaneously be in the service information fields of a packet relevant to the installation.

摘要： The disclosure relates to the acquisition of a binary analog signal at input of a digital integrated circuit after its range of voltage variation has been matched with that acceptable by the digital integrated circuit by means of a resistive divider bridge. It is usual to define the architecture of an ASIC digital integrated circuit on the basis of libraries of pre-characterized cells. The disclosed device is designed to increase the possibilities of choice open to the integrated circuit designer, in enabling him to one pre-characterized cell of a Schmitt trigger for its top switching threshold and another for its bottom switching threshold. It consists of a circuit comprising, at input, a bank of Schmitt triggers of different types, followed by a discrete-rendering logic circuit deducing the logic state of the binary input analog signal of the combination of the output states of the input Schmitt triggers.

摘要： A method of selecting information usable by a local unit connected to a digital transmission system includes cyclical scanning at fixed frequency of a list of programmed conditions stored in memory, acquisition of information on the transmission channels and activation of a selection process each time that the selection information of a message has been acquired. The selection process comprises a synchronization stage which waits for the scanning process to cross the start of the list of conditions. In a comparison sequence the selection information is compared with the conditions of the list. A selection variable is produced indicating if the message being received is of interest to the local unit or not. The method may be implemented through the use of a highly integrated interface.

摘要： Embodiments of the invention enable the integrity of data processed by a switch to be guaranteed better than 10−9 undetected erroneous frames per flight hour. To do this, rules for disabling ports are included in the switch management program. These rules include a maximum absolute admissible number of erroneous frames, to a maximum relative rate of admissible erroneous frames and a minimum number of erroneous frames constituting a significance threshold. Random errors are detected at the level of each frame due to the insertion of a CRC. Deterministic or data-dependent errors able to deceive systematically the CRC check are made random by means of a frame index.

摘要： This method consists in making a routing automaton carry out verifications on the integrity of the packets arriving at the packet switch, their periods of stay in the packet switch, their matching with the virtual paths that they claim to take as well as the routings proper, within the packet switch, of the datagrams that have satisfactorily undergone the verification. The routing automaton is provided with a random access memory of instructed values containing a table of virtual path local descriptors. The processing time of the automaton is divided into a repetitive sequence of time slots individually allocated to the different input ports of the packet switch.

摘要： An input/output controller interacts with a central processing unit of a computer which communicates with peripheral electronic equipment. The link with the central processor unit is produced with an input serial line and at least one output serial line. It receives instructions of a first type from the central processing unit and instructions of at least a second kind which are stored in the memory external to the central processing unit. These are processed using a sequencer device which allocates time slots to the instructions according to their type. This device is especially useful in the field of avionics and flight management systems.
