Control Unit
Design a vertical micro programmed control unit to generate 40 signals. Out of first 35 those only 3 signals can be active at a time. And remaining 5, anyone can be active anytime. The micro instruction of the control unit stores control signal information along with 3-bit MUX select and 12 bits address field. The size of the control memory required is?

Control Unit
Consider a microprogrammed control unit has to support 32 number of instructions. For each instruction execution control unit generate a sequence of 64 control words. Each micro instruction contains 3 fields: 118 control signals to support horizontal control unit, a MUX select field to select one of 8 inputs, and a next address field. The size of control memory needed is?

Microprogrammed approach
Microprogrammed control Unit is useful when very small programs are to be run. Shouldn’t this statement be true because microprogrammed approach uses decoder, which slows down speed, so large programs would take more time, and small ones less?

Vertical microprogramming mutually exclusive
A Hypothetical control unit supports 5 groups of mutually exclusive signals G1:2 G2:1 G3:4 G4:33 G5:25 What is the size of control memory (in bytes), if during any microinstruction atmost 1 control signal is active and the control unit ... signals can be active or none also right? That is the meaning of mutually exclusive right? Am I correct? @arjun sir?

self doubt
The uPC is not incremented in the following cases : (i)When an end microinstruction is encountered. (ii)When a new instruction is loaded into IR(instruction register) (iii)When a branch microinstruction is encountered and branch condition is satisfied. Someone, please explain the last point. I didn't get why it will not be incremented. These statements are from the standard book
