Abstract:
1. A method for transmission of messages, comprising the steps of: providing a plurality of microcontrollers comprising at least first and second microcontrollers connected by a data network comprising a communication system having at least one synchronized CAN bus and at least one dual-ported RAM which provides both rapid exchange of data and a buffered exchange of data; providing first and second transfer microcontrollers directly communicating with each other through said dual-ported RAM; providing an operating system on each of the microcontrollers; for a given communication task for sending a message, providing the first or second microcontroller serving as a transmitting microcontroller a routing table in which is stored routing information for executing said given communication task, said routing information comprising a list of the first or second transfer microcontroller which is adjacent the transmitting microcontroller and which is suitable for transfer of the message to said second microcontroller serving as a receiving microcontroller and a corresponding type of the communication system to be used for the transfer of the message between the transmitting microcontroller and the respective adjacent first or second transfer microcontroller; for transmission of said message to said receiving microcontroller, reading from the routing table the respective adjacent first or second transfer microcontroller and said corresponding type of said communication system; and transmitting the message to the adjacent first or second transfer microcontroller which transmits the message using the dual-ported RAM to said receiving microcontroller.
