Abstract: The invention concerns a multiprocessor system comprising processors PU0 to PUn and a common main memory. The memory is logically divided into at least two banks M0 and M1 and is interconnected with the processors by a bus 110. By means of control lines 111 to 118 a bus protocol is established so that one of said memory banks is accessed while another one of said banks is still busy.
