• How is physical address calculated in 8086?

  The 8086 addresses a segmented memory. The complete physical address which is 20-bits long is generated using segment and offset registers each of the size 16-bit. The content of a segment register also called as segment address, and content of an offset register also called as offset address.

• How do you calculate physical address value?

  This calculation can be expressed as: Physical address = SS (hex) x 16 + SP (hex).

• How to calculate 20-bit physical address for 8086?

  8086 has 20bit address line. So the maximum value of address that can be addressed by 8086 is 2^20 = 1MB. So 8086 can address the locations ranging between 00000 H to FFFFF H. This 1MB memory is divided into 16 logical segments, each with a memory of 64KB.
• The effective address is computed as 10H*DS+ [BX] + [SI]. 8. Relative Based Indexed: The effective address is formed by adding an 8-bit or 16-bit displacement with the sum of contents of any one of the bases registers (BX or BP) and any one of the index registers, in a default segment.
