PROBLEM TO BE SOLVED: To provide a data processing device which is less costly in terms of band width. SOLUTION: The present invention relates to a data routing and processing device comprising a data bus, a router (15) for managing communications on the data bus, data processing units (11, 12) and a local memory (16) for temporarily storing data. A transmitting processing unit (11) transmits to the router an identifier (ID1). The router comprises a communication table (151) which enables it to determine the receiving processing unit (12) based on the identifier. The router ensures a communication between the transmitting processing unit (11) and the receiving processing unit (12) depending on a value of an availability register (tag). If the receiving processing unit is available, data transfer is direct; if not, the data transfer takes place via the local memory (16). COPYRIGHT: (C)2003,JPO |
