WebThe effective address is the sum of offset register and displacement value. The default segments for BX and BP are DS and SS. For example: MOV [BX+5], DX In this example, the effective address is BX + 5 and the physical address is DS (shifted left) + BX+5. WebOct 13, 2024 · The offset address, which is a part of the address, is added to the start of the segment to address a memory location within the memory segment. For example, if the segment address is 1000H and the offset address is 2000H, the microprocessor addresses memory location 12000H. What is offset in memory?
WebMay 9, 2024 · The 8086 has 20 address lines (A19:A0) and 16 data lines (D15:D0). Actually the 16 data lines and the lower 16 address lines are the same pins, also called AD15:AD0. They function as address lines for the first part of the clock cycle, and data lines for the later part. Also important for addressing is a pin called BHE, "bus high enable".
