Design and Implementation a SOPC for FSB Controller

This paper presented fieldbus SOPC-based FSB (fast serial bus) controller using FPGA technology for CNC application, which used H/S(hardware/software) codesign method. This controller completed control of AL (application layer), DLL(data link layer) and PL(physical layer). In the controller, CAN-compatible hardware designed by VHDL handled with DLL and PL of FSB, while software run in soft processor implemented FSB AL protocol. The experimental results indicate that the SOPC-based controller is efficient and flexible, and the design cycle and cost of CNC system with FSB is reduced by using this fieldbus controller.
