Abstract

PURPOSE:To achieve a fast and slow motion of division circuits accurately at a determined timing by executing a fast and slow operation instruction when the circuits reach a fixed value where it is performed by a micro program instruction of a program memory. CONSTITUTION:When the output Q of division circuits 3-7 goes to 0,0,0,1 and 0, signals outputted from an inverter 25 are differentiated 8-11 and with a fast/slow operation instruction S5, the output of the inverter 25 is changed to a level L from a level H. With this falling, an NOR gate outputs a signal of level H to set or reset the division circuits 3-5 according to fast/slow motion data.
