Assume a large shared LLC that is tiled and distributed on the chip. Assume that the OS page size is 16KB. The entire LLC has a

size of 32 MB, uses 64-byte blocks, and is 32-way set-associative. What is the maximum number of tiles such that the OS has full flexibility in placing a page in a tile of its choosing?

Answer:

19 - 22 bits ( maximum number of tiles )

Explanation:

from the given data :

  • There is 60 k sets ( 6 blocks offset bits , 16 index bits and 18 tag bits )
  • Address has 13-bit page offset and 27 page number bits
  • 14-22 bits are used for page number and index bits

therefore any tour of these bits can be used to designate/assign tile number

so the maximum number of tiles such that the OS has full flexibility in placing a page in a tile of its choosing can be between 19 -22 bits

What is segmentation and paging?
iogann1982 [59]

Over the years, operating systems have sought to be more efficient, which is why it is vital that the use of main memory such as ram be as intelligent as possible, so that operating systems are more efficient.

Segmentation is a process of dividing the program into logical units, such as sub functions, arrays, variables, etc., making it possible to have processes divided into pieces so that it is easy to access each of the processes that this leads to its execution. Segmentation allows the programmer to contemplate the memory as if it had several address spaces or segments. References to memory consist of an address of the form segment number - offset.

Pagination is a technique where memory space is divided into physical sections of equal size, called page frames. The programs are divided into logical units, called pages, that are the same size as the page frames. In this way, an information page can be loaded in any page frame. The pages serve as an information storage unit and transfer between main memory and auxiliary or secondary memory. Each frame is identified by the frame address, which is in the physical position of the first word in the page frame.
