Question

1. The following instruction is executed. Assume that before execution, register R12 contains 0xA0, R15 initially contains 0x61, and the flags are ZF=0, SF=1, and CF=1. 0x indicates hexadecimal; do not include a 0x with your answer.

Instruction: CMP R12, R15

After execution, register R12 contains ________(in Hex) and the flags will be ZF=_____, SF=_____ and CF=_______

2. The following instruction is executed. Assume that before execution, register R13 contains 0x74, R11 initially contains 0x59, and the flags are ZF=0, SF=0, and CF=0. 0x indicates hexadecimal; do not include a 0x with your answer.

Instruction: CMP R13,R11

After execution, register R13 contains ________(in Hex) and the flags will be ZF=_______, SF=_______ and CF=______

3. Assume that before the instruction is executed, the flags are CF=0, ZF=0 and SF=0 and the Registers have the values AL=0x35BL=0x0F CL=0x25 and DL=0x78.

What are the values of the flags after the instruction ADD AL,0x90 executes?

CF = __________, ZF =_________, SF =_________

4. Assume that the Instruction Pointer, EIP, contains 9610 and the assembly language representation of the instruction in memory at address 9610 is JB 175. If the flags are currently CF=0, ZF=0 and SF=1 what is the value of the EIP after the instruction executes?
