PURPOSE:To operate efficiently and generate quickly a high-order curve which is decided by plural control points by performing a forward transfer operation applying a pipeline operation system with plural operation units which are cascaded to each other. CONSTITUTION:The clock signals are supplied from a control part 1 to plural operation units 20 through a signal line 100, and at the same time the coordinate value Pi (i=1-N) is delivered successively onto a signal, line 110 synchronously with supply of said clock signals. Then the value Pi is supplied to the 1st unit 20 together with a parameter t (0<=t<=1) supplied through a signal line 120. The same parameter t is also supplied through a signal line 121. The coordinate values of higher-order curves are successively delivered from the units 20 respectively and transmitted to the following stages through an output signal line 111. Then the coordinate value of the highest-order curve is obtained from a signal line 112 of the unit 20 at the final stage. |
