Question

Difference between direct and indirect addressing modes

Answer 1

Direct address is faster memory access.

Indirect address usually slower than direct addressing mode.

Answer 2

Difference between direct and indirect addressing modes:

• Addressing is a process which is used to operate an instruction.

• The Direct Addressing method addresses the memory directly but the Indirect Addressing method addresses the registers first and then goes to the memory.

• The Direct Addressing needs two memory locations in which operands will be stored in one location and the operator will be stored in the other and can be operated by addressing directly the locations.

• The Indirect Addressing needs three memory locations in which operands will be stored in one and the operator in the other. The third location is in the register for addressing the operands in the memory.

• By using this address in the register, it will operation will be done.

• The direct Addressing access the memory faster whereas the indirect addressing mode access the memory slower.
