    Hi,

    Thanks for your reply.


    Resolution:  SMULL RTemp, Rd, Rm, Rs
                              ADDS RTemp, RTemp, #0X80000000
                              ADDCS Rd, Rd, #0X00000001

    Because of          ADDS RTemp, RTemp, #0X80000000
                              ADDCS Rd, Rd, #0X00000001

    Output in Rd differ by 1.
    This is some thing wrong while we are try to rounded.
