Pointer and Index Registers
The pointers contain offset within the specific segments. The pointers BP, IP and SP generally containoffsets within thedata, code and stack segments respectively. The index registers are utilized as general purpose registers and for offset storage in case of indexed, and relative index andbased indexed addressing modes. The register SI is usually used to store the offset of source data in data segment while the register DI is utilized to store the offset of destination in data or extra segment. The index registers are specifically useful for string manipulations.
