Simplify the following boolean function in POS form using K-maps :
F (A, B, C, D) = Σ (0, 2, 4, 5, 6, 8, 10, 13, 15)
Also draw a logic diagram using only NAND gates. 5m Dec2005
K-Map for F is:
Thus, the simplified equations for F (A, B, C, D) = Σ (0, 2, 4, 5, 6, 8, 10, 13, 15)
are:
F = (|A+|B+D) (B+|D) (|C+|D)

Logic diagram using only NAND gates:-
Assume a compuier having 64 word RAM and cache memory of 8 blocks. Where can we find the main memory location 26 in cache jf
(i) Associative mapping is used;
(ii) Direct rnapping is used;
(iii) 2-way set associative (2 blocks per set) mapping is used.
Assume 1 word = 16 bits and block size = 32 bits Make suitable assumptions if any 5m Dec2005
