A compiler designer is trying to decide between two code sequences for a particular machine. Based on the hardware implementation, there are three different classes of instructions: Class A, Class B, and Class C, and they require one, two, and three cycles (respectively) The first code sequence has 4 instructions: 2 of A, 1 of B, and1 of C The second sequence has 5 instructions: 3 of A, 1 of B, and 1 of C Find out following questions: Which sequence will be faster? How much?

Assignment for Computer Architecture Instructions: The assignment is to create a program that adds the number 1/2 to itself a large number of times and adds the number 1/3 to itself a large number of times separately first using type float and then type double. It is to then compare the values of adding the numbers to multiplying 1/2 time the number of times added to compute the “same sum” in a different way. The program will also multiply 1/3 times the number of times 1/3 was added to itself to compute the “same sum” in a different way. The program will then compare these two methods at arrive for the same value and output the difference. Hint, the value for the ½’s will be the same for the smaller numbers of times, the 1/3’s will never be the same. The output from your program is to be to a *.txt file which you are to turn in along with your code. The program must first add the ½’s and 1/3’s using type float and compare to the value obtain using multiplication instead of addition.…

1. A program is running on a machine which has a total of 500 instructions, average cycles per instruction for the program is 2.5, and CPU clock rate is 1.78 GHz. Find the execution time of the program. 2. Consider a program whose instruction count is 50,000, average CPI is 2.2, and clock rate is 1.9 GHz. Suppose we use a new compiler on the same program for which the new instruction count is 40,000, and new CPI is 3.1, which is running on a faster machine with clock rate 2.5 GHz.
In python, Problem DescriptionProfessor Santos has decided to hide a secret formula for a new type of biofuel. She has, however, left a sequence of coded instructions for her assistant. Each instruction is a sequence of five digits which represents a direction to turn and the number of steps to take. The first two digits represent the direction to turn: • If their sum is odd, then the direction to turn is left.• If their sum is even and not zero, then the direction to turn is right.• If their sum is zero, then the direction to turn is the same as the previous instruction. The remaining three digits represent the number of steps to take which will always be at least 100. Your job is to decode the instructions so the assistant can use them to find the secret formula. Input SpecificationThere will be at least two lines of input. Each line except the last line will contain exactly five digits representing an instruction. The first line will not begin with 00. The last line will contain…
