  abstract= "Most motion control systems for mechatronic systems are
     implemented on digital computers. In this paper we present
     an FPGA based solution implemented on a low cost Xilinx
     Spartan III FPGA. A Production Cell setup with multiple
     parallel operating unit is chosen as test case. The embedded
     control software for this system is designed in gCSP using a
     reusable layered CSP based software structure. gCSP
     is extended with automatic Handel-C code generation for
     configuring the FPGA. Many motion control systems use
     floating point calculations for the loop controllers. Low
     cost general purpose FPGAs do not implement hardware-based
     floating point units. The loop controllers for this system
     are converted from floating point to
     integer-based calculations using a stepwise refinement
     approach. The result is a completely FPGAbased motion
     control system with better performance figures than previous
     CPUbased implementations."
