Abstract
The system according to the present invention for data transfer between microcomputer devices contains a standard protocol controller, a generally known ethernet controller, for example, as a coupling device instead of the known multiport RAM. Instead of a parallel data connection, the microcomputer devices are coupled to one another via a standardized, serial data connection, for example, ethernet. Using the functions of ethernet switches already known, the number of microcomputer devices in this system may be increased.
Claims11
A system for data transfer between microcomputer devices (1, 8), which each contain at least one microprocessor (2,9), a microprocessor bus (3, 10), a coupling device (4, 11) connected thereto, the coupling device (4, 11) providing a serial protocol, the data transfer being performed between the microcomputer devices (1, 8) via the coupling devices,
- characterized in that the microcomputer devices (1, 8) are spatially positioned within one system and each microcomputer device (1, 8) is assigned its own, separate power supply region (6, 13) and the coupling devices (4, 11) provide a standardized serial protocol.
