Explanation / Answer

ANSWER

GIVEN BY

Word is 4 bytes. Frame extent is 512 bytes = 29 bytes

So, offset field of elementary address strength of will be 9-2 = 7 bits

As the full amount digit of segment is given as 8 so, the piece integer playing field of the logical chat to will be 3 bits.

residual bits i.e 14 -(3 + 7 ) = 4 bits [as total size of consistent address is 14 bits] will be in the quantity of paper number grassland of the sound address.

commonsense address is specific as = 10010000000111

The original three bits are slice number

Therefore, piece number = 100

Next 4 bits are page figure

Then,

page number = 1000

at this occasion offset = 0000111

Now STBR is zilch but slice table base record .it contain the base address of the part stall (which is given as 127(in decimal)).

consequently STBR will surround the value 0000000001111111 .

now STBR + segment number = 127 + 4(as division number is 100) = 131

So in the division table 131th entry will hold the summon figure value i.e = 1000 = 8(in decimal)

Now top of page worktable address is 255.

So 255 + 8 = 263

So, 263th entry of the folio table will hold the cost of the edge figure where the lessons is there i.e = 01111

Now MAR will hold the speak to of this instruction which is not anything but edge number + offset = 0000011110000111.
