PROBLEM TO BE SOLVED: To access the same first group data holding medium storing the higher rank data and lower rank word and the second group data holding medium storing the lower rank data; each a data consisting of one word, from a control arithmetic means which is different in the access order of the first group and the second group data holding media. SOLUTION: A control arithmetic part 1 on which a control arithmetic means is mounted is made to output the FC code signal g to be the binary signal according to the kind of the control arithmetic means in addition to the selection signal a of the one bit of number signals. By the secondary selection signal b to be the output signal of an exclusive OR circuit 11 in which the selection signal a and the FC code g are made as input signals, the access order of the first group memory M1 of a first group data holding medium and the first group memory M2 of a second group data holding medium is determined. The value of the FC code signal g is changed from the value on one side to the value on the other side. As a result, the access order is changed from one order to the other order. |
