DATA SEGMENT

MOV AX, 05H[SI] ;;AX =3332H

LEA DI, DA2 ;;DI =0008H

MOV CX, AX ;;CX =3332H

ASSUME CS:CODE, DS:DATA

MOV BX, 05H[DI] ;;BX =11000H

DA2 DW 3 DUP(10,20)

END START

;;DX =3D32H

MOV DX, AX ;;DX =3D32H

展开完全

;;上述多线程 运行后:

(先解答第五题,待楼主采纳后再提供第六题的电路图)

CODE ENDS

MOV DS, AX

SUB CL, 1000H ;;CX =3332H -1000H =310002H

;;

ADD AX, 03[DI] ;;AX =3332H +0A00H =3D32H

SAR AX, CL ;;AX =33D2H右移2位 =0F4CH

CODE SEGMENT

DA1 DB "ABCD", "1234"

LEA SI, DA1 ;;SI =0000H

;;CX =310002H

DATA ENDS

;;AX =0F4CH

INT 3

;;BX =11000H

;;DI = 0008H
