Multimedia communication deals with the transfer, protocols, services, and mechanisms of discrete media data (such as text and graphics) and continuous media data (like audio and video) in/over digital networks. - determines the page number and offset of the virtual address - checks whether the page number is larger than the value in the page table length register - if it is, the MMU raises an exception - otherwise, the MMU uses the page table to determine the frame number of the frame that holds the virtual page, and combines the frame number and Therefore the physical address would be 56?

Thank you, The page size indicates how much bits represent the offset in the physical frame. The CPU has one or more registers which hold the address of that one byte which is being worked upon. Since you have only one level of page tables, the rest of the bits to the left represent the actual physical page. If Logical Address = 31 bit, then Logical Address Space = 2, If Logical Address Space = 128 M words = 2, If Physical Address = 22 bit, then Physical Address Space = 2, If Physical Address Space = 16 M words = 2, The Physical Address Space is conceptually divided into a number of fixed-size blocks, called, The Logical address Space is also splitted into fixed-size blocks, called, Physical Address = 12 bits, then Physical Address Space = 4 K words, Logical Address = 13 bits, then Logical Address Space = 8 K words, Page size = frame size = 1 K words (assumption). @DavidRicherby is correct You don't need a formula.
