Note: There are six questions in this paper. Question number 1 is compulsory and carries 30 marks. Attempt any three from the rest.
Q.1(a): Construct the Karnaugh map for the function:
F(a, b, c, d) = ? (1, 2, 3, 5, 7, 8, 10, 12, 13, 15)
Find the optimised function in Product of Sum (POS) form using this Karnaugh map.
| Q.1(b): In a XYZ machine the subroutine call instruction
GOSUB X causes the following micro-operations
[X] <- Return address
[X + 1 ] <- Pointer to the argument list
What are the drawbacks of this mechanism of subroutine call? Suggest an impleme: [5]
Q.1(c): What is the need of having many addressing nodes in a machine? Explain the displacement addressing modes and their application.: [5]
Q.1(d): What is the need of Master-Slave flip-flop? Explain the working principle of a master slave flip-flop with the help of logic diagram.: [5]
