Chapter 10, Problem 58E

Program Plan Intro

Paged memory management:

Paged memory management technique is to partition the main memory into a set of small fixed-sized blocks called as frames.

Logical address of paged memory management:

• The logical address in paged memory management begins as a single integer value.
• The logical address is written in the format of “<page, offset>”.
• Page number is got by the number of times the page size divides the address, and offset is remainder of the division.
• The given logical address in a paged memory management system is <2, 133>.
  • From this given data, the value “2” represents the page number and the value “133” represents offset.
  • The above value means the “133” bytes on page “2” of the process.

Physical address of paged memory format:

• To produce a physical address, the frame number in which a page is stored should be found out.
• Then, the frame number should be multiplied with the frame size.
• The multiplied value should be added with offset value to produce physical address.

The formula to bind logical address to the physical address is,

$\text{Physical address = Frame number * Frame size + Offset value}$        (1)

The following table is given table with specific page number and frame that the page belongs,

Page	0	1	2	3
Frame	5	2	7	3
