PURPOSE:To accelerate graphic plotting by reducing the number of times of memory access. CONSTITUTION:This device is provided with an address comparator 3 for detecting coincidence between plotting addresses A and AL of plural picture elements p1 and p2 in continuous plotting orders. Then, a plotting mask link circuit 4 is provided to output a link plotting mask MC of the plural picture elements p1 and p2 corresponding to an address coincident signal CA. Further, a plotting data link circuit 5 is provided to output link plotting data PC of the plural picture elements p1 and p2 similarly. |
