How to find logical address in 8086?
- Logical address is contained in the 16-bit IP, BP, SP, BX, SI or DI. It is also known as the offset address or the effective address. - The base segment address is contained in one of the 16bit contents of the segment registers CS, DS, ES, SS. of the memory.What is logical address in 8086 example?
To execute a program, the 8086 fetches the instructions from the code segment. The logical address of an instruction consists CS (Code Segment) and IP(instruction pointer). Example: If CS register contains 2500H and IP register contains 95F3H.How address is calculated in 8086 microprocessor?
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.- I learnt that the physical address is calculated by shifting the segment address (16-bit) left 4 times and adding it with the 16-bit offset address. The memory in the 8086 architecture is 1M.
