In which addressing mode, the effective address of the operand is generated by adding a constant value to the contents of a register?
The correct option is D Index mode
In Index mode addressing
mode, the effective address of the operand is generated by adding a constant
value to the contents of a register.
The address of the
operand is obtained by adding to the contents of the general register (called
index register) a constant value. The number of the index register and the
constant value are included in the instruction code. Index Mode is used to
access an array whose elements are in successive memory locations. The content
of the instruction code, represents the starting address of the array and the
value of the index register, and the index value of the current element. By
incrementing or decrementing index register different element of the array can
be accessed.
The term addressing modes
refers to the way in which the operand of an instruction is specified.
Information contained in the instruction code is the value of the operand or
the address of the result/operand.
