Assignment Task 

Q. 1 Draw schematic diagram to show what happens after the execution of the following instruction. a) LSS BX, (SI] (If before execution: DS= ABOOH, SS= 1750H, SP =FFFEH, SI=5000H) b) REP MOVSB ( If before execution: CX=2, D=1, DS=10D5H, SI=0A0BH, ES=6800H, DI= 8A50H) 
 

Q. 2 Suppose CX=D520H and BX=52EDH. Determine whether the BCA label will execute after the conditional jump instruction or not? Explain your answer. 
CMP CX, BX JG BCA 
 

Q. 3 Suppose that AX= 1895H, BX= 5EE8H, CX=0592H and SP=O1DEH. Give the contents of AX, BX, CX and SP after executing each step of the following instructions: 
PUSH BX XCHG AX, CX ADD CH, BL MOV BX, 00B5h PUSH CX POP AX
