I am new to vhdl I need to calculate the speed of dc motor for taking it as feedback for comparing with reference speed in closed loop.Is there any source code available or what is the way to do it.I am using vhdl for implementation of controller in fpga.

Which input signal are you reading to get the speed information, e.g. incremental encoder pulses? What's the range and intended coding for the speed output signal?

hi, I have this problem,too. I need to use encoder H_sense A and/or B to calculate speed of dc motor with vhdl. the way of calculation is not impoprtant. I use fpga board spartan 3. internal clock is 20 MHz and motor fed with 3.3 volt voltage.
