Question

Assume that a computer supports 20-bit physical addresses and runs an operating system that supports 24-bit virtual addresses that uses a 4Kbyte page size. Assume the virtual address 4A02 (from which leading zero's may have been omitted) is used. This address needs to be converted to a real (physical) address. Use hexadecimal notation for all your answers.

1.1) What is the number of the page table entry that will be used? (Include leading zero's if required.)

1.2) What offset will be used to determine the physical address? (Include leading zero's if required.)

1.3) Assume the relevant entry in the process’s page table is D4. What is the physical address corresponding to 4A02?
