Q2) Answer the following sentence with (True) or (False) and correct the false answer: (20 Marks) 1. CMPS is used with REPE, REPZ, REPNE and REPNZ. 2. Loop instruction is equal to JNZ instruction. 3. SAL and SHL have the same operation. 4. The instruction MOV BX,'B' is allowed. 5. Segment override prefix means we can use any segment register to have the physical address. 6. In CBW, the MSB of AX is copied to all the bits in DX. 7. The following piece of code is used to: Complement PF and CF LAHF AND AH, FOH XOR AH, OFH SAHF 8. In conditional jump, the next instruction is executed if the condition is not met. 9. Assume BL=11H, AX=FFB6 H, the result of executing IDIV BL is AX=FAFD H 10. The instruction queue in the BIU works on LIFO basis.

Identify all possible data hazards that might be present in the following code segment. For each hazard, list the type of hazard. (RAW, WAR, or WAW), the addresses of the instructions involved in the hazard, and the name of the register or memory operand that might have the hazard. Assume that R1, R2, etc. are registers while A, B, etc. are memory operands. The first operand is the destination while the second operand is the source. The numbers on the left are the addresses of the instructions. 140 ADD R1, A 141 ADD R2, B 142 ADD R1, R2 143 MOVE B, R1
