Vertical Encoding

What Does Vertical Encoding Mean?

Vertical encoding is a type of instruction set that encodes a field of an instruction word before being converted into signals that control functional units of a computer. It uses hard-wire logic or microcode base encoding to generate control signals for functional units.


Techopedia Explains Vertical Encoding

Vertical encoding is primarily the part of a computer / processor instruction set architecture that deals with micro set instructions. Vertical encoding works by implementing a decoder / encoder between the microinstruction register and the clock or control signals. Each instruction sent is decoded before being sent as a signal. It requires additional logic to convert or encode the instructions into corresponding signals; therefore, it also is slower than horizontal encoding.

Vertical encoding also restricts selecting more than one register for an operand and requires only one register per instruction field.
