Q4: To determine which code sequence will execute faster according to MIPS (Million Instructions Per Second), we need to compare the instruction counts of the two sequences. However, the specific instruction counts for the sequences have not been provided in the question. Please provide the instruction counts for both code sequences, and I'll be able to analyze and answer your question accordingly.
Q5: To determine which code sequence will execute faster according to execution time, we need additional information such as the clock cycles required for each instruction class in the machine. The given data only mentions the machine's clock rate, which is 100MHz. Without the specific clock cycle information for each instruction class, it is not possible to calculate the execution time of the code sequences accurately. Please provide the clock cycle information or any additional relevant details, and I'll be able to provide a more informed response.
