GATE IT 2005 | Question: 49
An instruction set of a processor has $125$ signals which can be divided into $5$ groups of mutually exclusive signals as follows: Group $1$ $:$ $20$ signals, Group $2$ $:$ $70$ signals, Group $3$ $:$ $2$ signals, Group $4$ ... signals. How many bits of the control words can be saved by using vertical microprogramming over horizontal microprogramming? $0$ $103$ $22$ $55$
