Register Organization of 8086

8086  has  a great  set  of registers  containing  special  purpose and general  purpose  registers.  All the 8086 resisters are 16-bit registers. The general purpose registers, may be utilized as either16-bit registers8 or -bit registers. The general purpose registers are either used for holding variables, data and intermediate results temporarily or for the other purposes like as counter or for storing offset address for some specific addressing modes etc. The special purpose registers are utilized as pointers, segment registers, offset storage registers for particular addressing modes or asindex registers. We will categorize the register set into 4 groups that are: General data Registers, Segment Registers, Pointer ad Index Registers, Flag Registers.
