x86 Memory Addressing Modes

Effective Address

effectiveAddress = BaseReg + IndexReg * ScaleFactor + Displacement

BaseReg = any general purpose register
IndexReg = Index Register - any gen purpose register except Stack Pointer Reg (ESP)
ScaleFactor = 1,2,4,8

Displacement = Constant offset encoded w/in instruction
