<p>PURPOSE:To perform simultaneously both the program input and processing by switching the 1st and 2nd selectors in coupling with each other and connecting alternately the 1st and 2nd memories to the 1st or 2nd CPU to perform control. CONSTITUTION:At the left side of the diagram the program data is stored to a memory 15 via a data processing part 21; while the processing is carried out via a processing part 22 by the program data stored in a memory 16 at the right side of the diagram respectively. The part 21 corresponds to an input device 11 and a CPU12; while the part 22 corresponds to a CPU14 and a drive device 13 respectively. Here selectors 17 and 18 are switched to each other as shown by buses of dotted lines. In such a case, the program data is stored to the memory 16 and the processing is carried out by the program data of the memory 15. Therefore the processing is carried out by the program memory of a memory at one side while the program data is stored to the memory at the other side. This operation is alternated by switching selectors.</p> |
