How do you calculate effective address in 8086?
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.
How the 20 bit effective address is calculated in an 8086 processor?
To access a specific memory location from any segment we need 20- bit physical address. The 8086 generates this address using the contents of segment register and the offset register associated with it. The BIU has a dedicated adder for determining physical memory address.
How do you calculate effective address of the register?
The effective address of the memory operand is calculated by adding the base address in register rs1 to the sign-extended 12-bit offset found in the immediate field.
Can you calculate the effective address of the memory location as per the DS register? Solution: No, the effective address of the DS register cannot be calculated from the given values because none of the given offset is an offset of the DS Register._{2 jan. 2021}
