PROBLEM TO BE SOLVED: To successively generate addresses jumping at a prescribed interval in a simple constitution by adding the 1st address data having a prescribed address interval to the 2nd address data, which show the positions that are successively shifted 1 every row to the 1st address data at each address interval. SOLUTION: At a write address generation part 51, the write addresses WA10 are generated at every prescribed address interval and in response to the capacity of 1st and 2nd interleave memories 2 and 3. Thus, the order of addresses WA10 is rearranged at random, when the data are written. Then the part 51 sends the generated addresses WA10 to the 1st and 2nd address selectors 6 and 10 at every interval of 18 addresses. A memory switch control part 4 supplies the addresses WA10 to the memory 2 or 3. |
