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

Microprogramming
In horizontal micro-programming the control word is of the following format: Flag bits Control Signal Bits Next Control Word Address I know that the Control Signal bits denote which micro-operation to execute. My question is does 1 bit of control ... that Scenario 2 is the correct one i.e. 1 control signal bit in horizontal microprogramming denotes 1 micro-operation entirely?
