Which of the following addressing modes permits relocation without any change?
Which of the following addressing modes permits relocation without any change?
The correct option is C Base register addressing
Base register addressing modes permits relocation without any change.
Base register addressing:-In this mode, content of base register
is added to the address part of the instruction to obtain effective address. A
base register is assumed to hold a base address and the address field of the
instruction gives a displacement relative to the base address with a base
register, the displacement values of the instruction do not have to change only
the value of the base register requires updating to reflect the beginning of a
new memory of constant.
Base addressing, a
register points to the base of the structure and the effective address is
obtained by computing an offset from the base. The base address register can be
loaded at run time to point to the base of the structure so the code doesn't
have to be modified.
