- Used for vertical microinstructions (not for horizontal microinstructions) • The advantage of vertical microinstruction - More compact (fewer bits) at the expense of a small additional amount of logic and time delay Decoder Basic Concepts In vertical microcode, a set of true control signals is represented by a shorter code Vertical µcode only allows RTs in a step for which there is a vertical µinstruction code Thus vertical µcode may take more control store words of fewer bits Horizontal Versus Vertical Microcode Schemes S 2/e C D A This feature is not available right now.

Each line represents a set of micro operations that will be executed at a particular time and known as microinstruction. For each micro instruction, binary numbering system representing the microinstruction is determined for each control involved. Horizontal Vertical Microinstruction Branching in horizontal microprograms is also more complicated than in the vertical case. Each horizontal microinstruction is likely to have at least one branch.

Horizontal lines are parallel to the horizon or parallel to level ground. They have a slope of zero and are parallel to the x-axis on a graph. The two main variations of microprogramming are the horizontal and vertical methods. In the previous section, we already saw some distinction between horizontal and vertical next-state organizations.
