WebInter Segment Direct Addressing Mode. The new Branch location is specified directly in the instruction Both CS and IP get new values, as this is an inter-segment branch. … This requires space in an instruction for quite a large address. It is often available on CISC machines which have variable-length instructions, such as x86. Some RISC machines have a special Load Upper Literal instruction which places a 16- or 20-bit constant in the top half of a register. That can then be used as the base register in a base-plus-offset addressing mode which supplies the low-order 16 or 12 bits. The combination allows a ful… cpt code revision aka

WebBased 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 ... WebDisplacement Addressing Mode. In this the contents of the indexed register is added to the Address part of the instruction, to obtain the effective address of operand. EA = A + (R), In this the address field holds two values, A(which is the base value) and R(that holds the displacement), or vice versa. Relative Addressing Mode.
