Design of Movement- control System Based on SOPC

Design a new Motion Controller based on SOPC.This Motion Controller take PC as upper computer,and use digital control mode to carry out three coordinate motion and function of related I/O. It take SPI as the communication between upper computer and lowwer computer,run at high speed and perfectly carry out Motion Controller's real- time control. Introduce FPGA which simplified the structure of motion controller hardware. The system has character of open structure、use conveniencly、cost lowly、credibility of performance、small structucture.So this Motion Controller can achieve at custom applicaton flexibly.
