Question 32

Horizontal microprogramming

A
does not require use of signal decoders
B
results in larger sized microinstructions than vertical microprogramming
C
uses one bit for each control signal
D
all of the above
Question 32 Explanation: 
In horizontal microprogramming the instruction size is less as compared to vertical microprogramming. So, there is no need for decoding. But, one bit is used for all control signals to execute the microinstruction. If the bit is set to ‘1’ the control signal field is activated. If the bit is set to ‘0’ the control signal field is deactivated.
