ABSTRACT:
The present invention relates to a data routing and processing device comprising a data bus, a router for managing communications on the data bus, data processing unit and a local memory for temporarily storing data. A transmitting processing unit transmits to the router an identifier. The router comprises a communication table which enables it to determine the receiving processing unit based on the identifier. The router ensures a communication between the transmitting processing unit and the receiving processing unit depending on a value of an availability register. If the receiving processing unit is available, the data transfer is direct; if not, the data transfer takes place via the local memory.
