Displacement and Stack Addressing mode - computer architecture:

Displacement Addressing:

In displacement addressing mode there are three types of addressing mode. They are following:

  I.          Base register addressing

  II.         Indexing addressing.

  III.        Relative addressing

This is a grouping of register indirect addressing and direct addressing. The value contained in 1 address field. Directly A is used and the other address refers to a register whose contents are added to A to generate the effective address.

Stack Addressing:

Stack is a linear array of locations which referred to as last-in first out queue. The stack is a booked block of location, deleted and appended only at the top of the stack. Stack pointer is a register which hold the address of top of stack location. This mode of addressing is also called as implicit addressing.
