8086 Addressing Modes And Physical Address Calculation Examples Addressing modes in 8086 microprocessor. 5. based relative addressing mode. this addressing mode uses a base register either bx or bp and a displacement value to calculate physical address. physical address= segment register (shifted to left by 1) effective address. the effective address is the sum of offset register and displacement value. the default segments for bx and bp are ds.

8086 Addressing Modes And Physical Address Calculatio Vrogue Co The address calculated when bp is taken as the offset gives the starting address of the stack. the address when sp is taken as the offset denotes the memory location where the top of the stack lies. therefore, the effective address for both these cases is: (ss x 10h) sp = 3640h x 10h 1735h. = 36400h 1735h. Tutorial 3 : 8086 addressing modes and physical address calculation. 26 mins. microprocessors and interfaces tutorials. problems and solutions, solved examples on 8086 memory organization, physical address generation, 8086 architecture, physical address calculation, segment address, offset address, code segment, data segment, effective address. 8086 addressing modes and physical address calculation : examples solved problems and solutions. Based addressing mode. in this addressing mode, the offset address of the operand is given by the sum of contents of the bx bp registers and 8 bit 16 bit displacement. example mov dx, [bx 04], add cl, [bx 08] indexed addressing mode. in this addressing mode, the operands offset address is found by adding the contents of si or di register and 8.

Addressing modes. Effective address of data is computed as 10h*ds [bx] [si] 50h. there are two addressing modes for control transfer instructions. intrasegment mode: if the destination location lies in the same segment the mode is called. intrasegment. intersegment mode: if the location to which the control is to be transferred lies in a different.
