Question

Suppose the page size in a computer system using single-level page-based memory management is 4K bytes, calculate the page number and the offset in hexadecimal for logical addresses 0x17C244 and 0x899 (hexadecimal numbers).

Answer 1

page size is 4K bytes => 2² x 2¹⁰ => 2¹² bits necessary for offset


1) 0x17C244

=> 0001 0111 1100 0010 0100 0100 --> First 12 bits are page number and last 12 bit is the offset

=> Hence the Page number is 0x17C and Offset is 0x244


2) 0x899

=> 1000 1001 1001 --> First 12 bits are page number and last 12 bit is the offset

=> Hence the Page number is 0x000 and Offset is 0x899
