2. Address Displacements

• Address displacement is a constant value added to the effective address.

• A direct memory specifier is the most common type of displacement:

      table   WORD    100 DUP (0)
              .
              .
              .
              mov     ax, table[ esi ]
  

• In relocatable expression table[ esi ] , the displacement is table, providing the base address of an array

• ESI holds an index to an array element. The ESI value is calculated at run time, often in a loop.
