Please answer this question about "logical address translation" Thanks. Check all that apply. Check all that apply to logical address translation. Different CPU may have different translation schemes The memory management unit may be inside the CPU The address translation consists always of an addition Address translation is implemented in software The physical address is always different from the logical address

There suppose to be 2 answer correct, please choose 2. Thanks

Answer #1

PLEASE FIND THE ANSWER(S) and EXPLANATION BELOW.

The correct answers are:-

OPTION A and C

EXPLANATION:-

  • In the logical address translation, we will take the address of base register and add it to the limit register always.
  • Hence, it always consists of an ADDITION. OPTION C is correct.
  • For this translation, different CPU can have different translation schemes based on the limit register. Hence OPTION A is correct.
  • The physical address can be same as the logical address if the base register is ZERO. Hence OPTION E is wrong.
  • The address translation may not always be done in the software because this can be done in hardware also. Hence OPTION D is wrong.
  • CPU will not have a MMU.
  • An MMU will be different from the CPU used to do this translation. Hence OPTION B is wrong.
