80x86 Addressing Modes

• Register Indirect

  • mem[reg]
  • not ESP or EBP

• Base + displacement (8 or 32 bit)

  • mem[reg + const]
  • not ESP or EBP

• Base + scaled Index

  • mem[reg + (2scale x index)]
  • scale = 0,1,2,3
  • base any GPR, Index not ESP

• Base + scaled Index + displacement

  • mem[reg + (2scale x index) + displacement]
  • scale = 0,1,2,3
  • base any GPR, Index not ESP
