PURPOSE:To enable high-speed exact communication control by making the lengths of respective communication lines respectively equal, forming a cross bar switch as an integrated circuit and making all the distances among respective processing elements almost electrically equal. CONSTITUTION:The units of the sets of respective communication lines 13 to be relatively arranged on respective bus wiring boards 7 with cross bar switches overlapped on the same axial line form parallel buses and the respective communication lines 13 are respectively allocated to the data lines, address lines and control lines, etc. According to a procedure decided in advance, a control means 16 controls the opening / closing of each contact in a cross bar switch 9. Therefore, since the lengths of the respective communication lines 13 are made respectively equal and the cross bar switch 9 is formed as the integrated circuit and made extremely compact, all the distances among respective processing element are made almost electrically equal and all the communication distances among respective processing elements are almost uniformed. Thus, high-speed exact communication control is enabled. |
