Abstract

PURPOSE: To obtain a controller available for the same operation as that of an arithmetic control part at a normal side even if either arithmetic control part gets out of order.
CONSTITUTION: Output register A71 is connected to data bus 75 of control part A12 and when select signal 76 to this output register is "1", data on bus 75 are taken in and hold. Further, when select signal 77 to input gate A74 is "1", the gate output the data held by output register B73 onto bus 75. Register B73 and input register B72 of control part B13 function in the same way. For example, data written to register 71 by control part A12 are held by register A and when input register B72 is read by control part B13, the data held in register A are read into control part B via gate B. In this way, data transfer from control part A to control B is carried out.
