Memory Addressing Modes (Part 2/2) ||

Memory Addressing Modes
Based addressing mode
In this addressing mode, the offset address of the operand is given by the sum of contents of the BX/BP registers and 8-bit/16-bit displacement.

Example
MOV DX, [BX+04], ADD CL, [BX+08]

Indexed addressing mode
In this addressing mode, the operands offset address is found by adding the contents of SI or DI register and 8-bit/16-bit displacements.

Example
MOV BX, [SI+16], ADD AL, [DI+16]

Based indexed addressing mode
In this addressing mode, the operands offset is computed by adding the base register contents. An Index registers contents and 8 or 16-bit displacement.

Example
MOV AX, [BX+DI+08], ADD CX, [BX+SI+16]
