Differences of horizontal and vertical micro code - Computer architecture and design

Explain the differences of horizontal and vertical micro code

Horizontal Micro Code

- In this types of code the micro code contains the control signal without any intermediary.

- Horizontal micro code instruction contain a lot of signals and hence due to that the number of bits also increase.

Vertical Micro code.

- In case of vertical micro code every action is encoded in density.

- Vertical micro code are slower but they take less space and their actions at execution time need to be decoded to a signal.
