A process for automatically detecting and configuring with the throughput of a network, in which a device: (a) goes into a listen mode; (b) obtains a triplet of successive transitions in a transmitted signal, the triplet delimiting first and second signal levels, one dominant and the other recessive; (c) measures the duration of each of the first and second levels; (d) as a function of the measured durations, obtains a new throughput configuration by determining values for parameters that define a bit length L; (e) validates the new throughput configuration; (g) if at least one throughput adaptation condition is verified, goes into a normal mode, otherwise obtains a next transition of the signal, which delimits with the last previous transition a new level of the signal, then measures the duration of the new level and reiterates steps (d) to (g) taking account of the new signal level.

Process for automatically detecting the throughput of a network, particularly of the can bus type and for configuring with the detected throughput by transition analysis, and corresponding device

An arbitration device is provided, which is designed to be connected between, on the one hand, a first and a second module and, on the other hand, storing means forming a memory workspace. This arbitration device includes a detector for detecting one or more requests coming, concurrently or not, from the first and second modules, for the purpose of accessing the memory workspace.
