Q. Salient features of direct addressing mode?

A number of salient points about this technique are:

This scheme offers a limited address space since if address field has n bits then memory space would comprise 2ⁿ memory words or locations. I.e. for illustration machine of Figure above direct addresses memory space will be 2¹⁰.

• The effective address in this technique is described as address of operand which is,

EA <-- A and (EA in the above illustration will be 500)

D = (EA) (D in the above illustration will be 7)

The second statement implies that the data is stored in memory location specified by effective address.

In this addressing technique only one memory reference is needed to fetch the operand.
