PURPOSE:To realize flexible and expandable message exchange by using a mail box in a single processor by using one or more processors as master processors and the remaining processors as slave processors and providing the mail box, etc., in the master processor. CONSTITUTION:One or more processors among plural processors 30 and 40 are used as master processors 30 and the remaining processors are used as slave processors 40 and a mail box 32 and a mail box directory 33 for managing mail box numbers and names are provided in the master processors 30. When the transmission task 41 of a specific slave processor 40 transmits a message, the master processor 30 registers the mail box name in the mail box directory 33 and gives the mail box number to the task 41 and the task 41 uses the number for message transmission thereafter. Therefore, flexible and expandable message exchange can be realized by using simple software while the function of conventional mail box in a single processor is utilized. |
