PURPOSE: A device and method for transmitting an event between tasks is provided to transmit and receive event information conveniently in a system, which uses many processors as a switching system. CONSTITUTION: A message transmission unit maintains a wait state(100). The message transmission unit checks whether event data are received or not in the wait state(102). If event data do not received, the message transmission unit checks whether an update signal of destination transmission table data is received(104). If update signal of destination transmission table data is received, the message transmission unit updates data using the destination data received from a man machine processor(106). If event data are received, the message transmission unit reads the destination transmission table and checks the destination of the received event(108). The message transmission unit checks whether a receiving task corresponded to the destination as the checking result is existed(110). If the receiving task corresponded to the destination is existed, the message transmission unit transmits the generated event message to the corresponding destinations(112).
