Thank you for your response.
After having a reasonable amount of log data, I want to perform some type of analsys at run time, e.g., no. of unique addresses, total no. of addresses, frequency of occurences of each addresses etc.

What makes you think that the log of physical addresses will tell you anything
useful or interesting?
Hint: Pretty much all physical pages usable for process space are identical as far
as the kernel is concerned, and if a virtual or disk cache page is pulled into memory
from disk more than once, the same virtual page can end up in different physical
pages.each time.

Are you trying to do this *at runtime in real time*, or is post-run analysis OK?
