PURPOSE:To realize the virtual output of the continuous data to the outside by using the small number parts of an input address to generate an interpolation coefficient. CONSTITUTION:The input data are successively written into the addresses of the memories 4a-4d so that the adjacent addresses are different from each other. At the time of reading the integer parts X and Y on an input address including a small number are used to take the discrete data around the input address out of the memories 4a-4d against said input address. At the same time, the small number parts (x) and (y) of the input address are used to produce an interpolation coefficient from a ROM 9. Then the continuous data are produced by means of said interpolation coefficient and discrete data and outputted via a register 14. Thus the virtual output of the continuous data is attained to the outside. |
