Question 1: A two level memory system has eight virtual pages
on a disk to be mapped into four page frames (PFs) in the main
memory. A computer program generated the following page trace:
2, 2, 1, 0, 7, 6, 1, 0, 5, 6, 6, 3, 2, 3, 7, 6
(a) Sketch the successive virtual pages residing in the four page
frames with respect to the above page tracing using the LRU replacement
policy. Compute the hit ratio also. Assume the PFs are initially empty.
(b) Repeat part (a) for the FIFO and Optimal algorithm and calculate the hit ratio.
Question 2: Study any 64-bit microprocessor architectures and discuss
the following features briefly.
(a) Bus architectures
(b) H/w support to memory management
(c) Pipeline architecture
