PURPOSE:To always and stably obtain priority data by connecting the output of a latch circuit in a basic circuit block to one of the input of a selection circuit in the basic circuit block of a next stage and displaying the output of a latch circuit in the basic circuit block of the last stage as an image pattern. CONSTITUTION:A pattern shift circuit 41, the selection circuit selecting the data of which priority order is high among the output data of the pattern shift circuit 41 and the data of a last stage and the latch circuits 49 and 50 temporarily storing the data outputted by the selection circuit are made to be the basic circuit block. Then the plural pieces of the basic circuit block are repeatedly constituted, the output of the latch circuit 49 in the basic circuit block is connected to one of the input of the selection circuit in the basic circuit block of the next stage and the output of the latch circuit 50 in the basic circuit block of the last stage is displayed as the image pattern. Thus when the operation speed is quick, the priority data can be stably obtained. |
