PROBLEM TO BE SOLVED: To improve the efficiency when loading non-placed words on a large number of contiguous addresses. SOLUTION: A selector 8 selects the address of the address signal or the address with 2 added thereto based on the access number. Based on the address of the selected result, two placed words allocated to addresses are read from memories 16 and 17, and one of the two words is stored in a register 20 or 21. Selectors 22 and 23 select two non-placed words not allocated to addresses from the words stored in the register 20 or 21 in the previous access and the two placed words presently read from the memories 16 and 17.
