Message interchange system among microprocessors connected by a synchronous transmitting means (1, 2), in which a microprocessor (PU), in order to send a message to another microprocessor, transfers the message words, as well as a state word, to a conventional read-and-write memory unit (ME), then it sends a signal enabling the operations and a signal enabling the reading in said memory unit (ME) to a first logic circuit (LC) that continues to autonomously transfer said messages from said memory unit (ME) to said transmitting means (1, 2) and in which a microprocessor in order to receive a message from another microprocessor sends to said first logic circuit (LC) a signal enabling the operation and a signal enabling the reading in said memory unit (ME), said logic uit (LC) receiving also an acknowledgement signal of a start message word. |
