Question

Assignment-I

Write the output for the following instructions

1. MOV B , A

            Before instruction execution, the contents of registers B and A are         

                        R_d= B= XB_H

                        R_s= A = 1F_H

             After the execution of instruction.        

                        R_d= B = ?

                        R_s= A = ?

2. ADD B

If A= E 3_H

  B=  0 4_H

then after the  execution of the above instruction the content of A = ?

3. SUI 03_H

If the value of A = 15_Hthen after the execution of the above instruction and the result A = ?

4. ANA B

   If         A  =    95_H   =   1001 0101

  And      B  =    44_H    =  0100 0100

Then ANA B results in A =   ?

5. ORA B

   If     A   =     8 4_H  =   1000 0100

And    B   =    B 3_H   =     1100 0011

        Then ORA B results in A =   ?
