ISRO | ISRO CS 2008 | Question 62
Consider a logical address space of 8 pages of 1024 words mapped into memory of 32 frames. How many bits are there in the logical address?
(A) 13 bits
(B) 15 bits
(C) 14 bits
(D) 12 bits
Explanation: logical address space = 8 pages of 1024 words
number of bits in logical address space = p (page bits) + d (offset bits)
number of bits = log28 + log21024 = 3 + 10 = 13 bits
Option (A) is correct.
