• Some vertical microcode is just the assembly language of a simple conventional computer that is emulating a more complex computer.
• Microcode can be characterized as " horizontal " or " vertical ", referring primarily to whether each microinstruction controls CPU elements with little or no decoding ( horizontal microcode ) or requires extensive decoding by combinatorial logic before doing so ( vertical microcode ).
