[0003] After searching the literature of the existing technology, it was found that in the article "Development and Application of Motion Control Card Based on C8051" published by Wang Ting et al. However, this technology has the following disadvantages: the C8051F060 single-chip microcomputer is used as the control core, and the interpolation speed is relatively slow; the IO ports of the single-chip microcomputer are few, which limits the hardware assignable address of the motion control card; the logic circuit is complex and the cost high
