Consider a computer system with a 30-bit logical address and 4-KB page size. The system supports up to 512 MB of physical memory. How many entries are there in each of the following? Assume that each page table entry is 4 Bytes. c. A conventional single-level page table? d. An inverted page table? e. A two-level hierarchical page table? 2. Consider a virtual memory system with a 50-bit logical address and a 38-bit physical address. Suppose that the page/frame size is 16K bytes. Assume that each page table entry is 4 Bytes. a. How many frames are in the systems? How many pages in the virtual address space for a process? b. If a single-level page table is deployed, calculate the size of the page table for each process. c. Design a multilevel page table structure for this system to ensure that each page table can fit into one frame. How many levels do you need? Draw a figure to show your page systems
1. Consider a computer system with a 30-bit logical address and 4-KB page size. The system
supports up to 512 MB of physical memory. How many entries are there in each of the following?
Assume that each page table entry is 4 Bytes.
c. A conventional single-level page table?
d. An inverted page table?
e. A two-level hierarchical page table?
2. Consider a virtual memory system with a 50-bit logical address and a 38-bit physical address.
Suppose that the page/frame size is 16K bytes. Assume that each page table entry is 4 Bytes.
a. How many frames are in the systems? How many pages in the virtual address space for a
process?
b. If a single-level page table is deployed, calculate the size of the page table for each process.
c. Design a multilevel page table structure for this system to ensure that each page table can fit
into one frame. How many levels do you need? Draw a figure to show your page systems
