PURPOSE:To make it unnecessary to execute a special processing for connecting a data, and to execute a data connection between central processing circuits by writing data information in a read-out/write storing circuit connected to its central processing circuit, and simultaneously, writing it in a read-out/write storing circuit connected to other central processing circuit, as well. CONSTITUTION:An access to a storing circuit 1 by the first central processing circuit and an access to a storing circuit 1' by the second central processing circuit are always executed preferentially. An operation for writing the data information which has been written to the storing circuit 1 from the first central processing circuit, to furthermore the storing circuit 1', and an operation for writing the data information which has been written to the storing circuit 1' from the second central processing circuit, to furthermore the storing circuit 1 are executed, when a preferential access is not being executed. In this way, each central processing circuit can execute the respective processings without minding a data connection to other central processing circuit. |
