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 support 256 control word memory?
My approach;
8(256cw)+(2+1+3+6+5) bits=25bits
The total size is 25*256/8bytes
Answer key
8+(1+1+2+6+5)=23bits
For all the groups either 1 of the signals can be active or none also right? That is the meaning of mutually exclusive right?
Am I correct?
@arjun sir?
