Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for transmitting data blocks between the source processor and destination processor of a multiprocessor system. SOLUTION: An intelligent bus interconnection unit(IBIU) functions as an automatic device, receives an instruction from the source processor by using a control block supplied by the source processor and supplies the instruction to the destination processor. The IBIU receives the information of the data block described by the contents of the relating control block and then sends the data block to the destination processor together with the control block relating to it. The data block is transmitted by using one of the plural levels of priority. The process of transmitting the data block is decomposed into the processes of transmitting a series of sub blocks.
