Consider two different implementations, M1 and M2, of the same instruction set. There are five classes of instructions (A, B, C, D, and E) in the instruction set M2 has a clock rate of 3,300 MHz. The average number of cycles for each instruction class and their frequencies (for a typical program) are as follows: Instruction Class Machine M1 Machine M2 Frequency
Cycles/Instruction
Frequency
A 1 2 60%
B 2 3 30%
C 4 4 10%
(a) Calculate the average CPI for each machine, M1, and M2.
(b) Calculate the average MIPS ratings for each machine, M1 and M2.
(c) Which machine has a smaller MIPS rating? Which individual instruction class CPI do you need to change, and by how much, to have this machine have the same or better performance as the machine with the higher MIPS rating (you can only change the CPI for one of the instruction classes on the slower machine)?

Write a function that draws a pool ball. this function should take as parameters, the color, the number that should go on the pool ball, and the location of the center of the pool ball. the radius of the pool balls should be pool_ball_radius, and the font of the number should be pool_ball_font. the text of the pool ball font should be white. drawpoolball(color.orange, 5, 100, 100); drawpoolball(color.green, 6, 50, 200); drawpoolball(color.red, 3, 150, 350); drawpoolball(color.blue, 2, 250, 140); to center the numbers on the pool ball, you should use the getwidth() and getheight() methods. you are allowed to call these methods on your text object, such as txt.
