Maybe I have an interesting example for this subject "FPGA & Motor Control":
There is an article available describing an example of a multi channel stepper motor control with a working secure stall detection algorithm by real time analysis of the motor electronic behavior performed by a xilinx spartan 3 FPGA:
Blog Doing Math in FPGAs Tom Burke 2 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
