Microprocessor

What is the physical address of the instruction if the Code Segment register (CS) has the value 2000 and the instruction pointer (IP) register has the value 100? What value will be in the AX register after the instruction MOV AX,[3000] is executed? (REMEMBER THAT ALL NUMBERS ARE HEXADECIMAL!). What value will be in the CI. register after these instructions are executed?. MOV DH,04. MOV CL,06. ADD CL,DH What value will be in the CH register after these instructions are executed?, MOV BX, 4002 MOV CH, 04, ADD CH,[BX], What value will be in the CH register after these instructions are executed? MOV CH,03, MOV BL, 07, SUB CH, BL, What value will be in the Al, register after these instructions are executed? MOV BX, 1500. MOV AL,[BX | SI]. What value will be in the AH register after these instructions are executed? MOV AH,06, MOV BX, 1000. ADD AH, [BX SI]. What value will be in the AL register after the following instruction is executed? MOV BI,05. MOV AI,02. MOV BL,AL, The following instruction will give an error. Explain why. MOV BX,[AX]. Explain the purpose or use of the w hit in op codes. Write the hexadecimal code for each of these instructions using die information attached. Show your work. MOV CI, DL, MOV DX, 1234. MOV [2468], CX. MOV CX, [BX D 4532]. MOV[BP + SI - 20)], DX

Solution

Physical address of the instruction=Contents of CP+Contents of IP

=2000+100

=2100
