Central Processing Unit Q.7

7The microinstructions stored in the control memory of a processor have a width of 26 bits. Each microinstruction is divided into three fields: a micro-operation field of 13 bits, a next address field (X), and a MUX select field (Y).
How many bits are there in the X and Y fields, and what is the size of the control memory in number of words ?

Option : A
Explanation : Control memory processor has 26 bit microinstruction divided into three field microoperation field is 13.
So, next address field (X) = 10
MAX select field = 3
Size of control = 2¹⁰ = 1024
