Q. Drawback of indirect addressing?
• Drawback of this scheme is that it needs two memory references to fetch actual operand. First memory reference is to fetch the actual address of operand from memory and the second to fetch actual operand using that specific address.
• In this technique the word length determines the size of addressable space as actual address is stored in a Word. For illustration the memory having a word size of 32 bits can have 232 indirect addresses.
