ABSTRACT:
A parametric curve generating device for developing a Bezier curve is provided. The device is capable of executing a high speed division operation with a limited magnitude of hardware scale. Adders perform calculations that are stored in registers. Convergence discrimination circuits discriminate whether data stored in the registers converge. Subsequent processing varies depending on the discrimination result. A stack memory is used to store data from the registers.
