Is this Code Mealy or Moore?

Would you mind giving me an example of a registered output?

Thanks a lot,

just get Z out into a separate process and put clock edge statement.

By the way I am just curious why design it the hard way. If it is me I will just do this:

--clocked process

shift <= shift(2 downto 0) & data;

--

z <= '1' when shift = "0110" else '0';

The shift register keeps history of previous inputs instead of state machine.

in your second process many of your z assignments are not needed. You can just use default z <= '0' at top then update in last state.
