InternetComputersNetwork

In this post, we will understand the difference between direct addressing mode and indirect addressing mode −

Direct Addressing Mode

  • In this mode, the address field contains the effective address of the operand.

  • This addressing mode requires one memory reference only.

  • It is a quick addressing mode.

  • There is no further classification in this mode.

  • There are no further calculations required to perform the operation in this addressing mode.

Indirect Addressing Mode

  • In this mode, the address field contains reference of the effective address.

  • It requires two memory references.

  • It is slower in comparison to direct addressing mode

  • It can be further classified into two categories.

  • It requires further calculation to determine the effective address of the operand.
