I have been given the format for page table entries:
Bit 23: Valid Bit
Bit 22: Modify Bit
Bits 22-18: LRU Bits
Bits 17-0: Frame Number
Im told that the system uses 32-bit virtual addresses and pages that are 8192 bytes in size.
How could I calculate the maximum amount of physical memory the system can contain?
So you have 18 bits for page numbers. How many possible numbers (and therefore pages) can be represented by 18 bits?
From the above you’ll find how many pages there can be. Then each page has 8192 bytes. How many bytes are there in all possible pages?
