In view of the shortcomings of traditional CNC based on PC and the card of dedicated motion controller, as well as ARM and DSP multi-processor in lack of communication. Proposed a embedded pro-cessing scheme based on multi-core heterogeneous OMAPL138 processor, and construction of a CNC con-troller hardware system, while taking advantage of the field programmale feature of FPGA to complete con-troller extension module design. The design solves the issues which PC lacks of dedicated resource and real-time control, and solves the defects of data loss, error-prone and difficult to maintain in multiprocessor com-munication, and implements the modern CNC system demand of high performance, modularity, flexibility and openness.
