<p>PURPOSE:To ensure the effective arrangement of layouts when a retrieving circuit is shared by plural output lines by placing the retrieving means at positions adjacent to the destination display bit storage means. CONSTITUTION:A retrieving circuit 61 is placed adjacently to the destination display bit memories 511-5k1, and a retrieving circuit 62 is placed adjacently to the memories 512-5k2. Then a retrieving circuit 63 is placed adjacently to the memories 513-5k3, and a retrieving circuit 64 is placed adjacently to the memories 514-5k4 respectively. In such a constitution, the wiring set between the blocks of the destination display bit memories and the retrieving circuits never affects others. Furthermore it is just required to repeat the arrangement of combination layouts of the bit memories and the retrieving circuits by frequency equal to the number of destination display bits. Thus the layout working efficiency is improved.</p> |
