computer architecture

3) A program consists of 8 floating point instructions and 12 integer instructions. Floating point instructions take 5 cycles and integer instructions take 2 cycles each. Assuming that the processor has a clock rate of 200.0 MHz: a) Show that the total cycles is equal to 64. b) Show that the total instructions is equal to 20. c) Show that the average cycles per instruction is equal to 3.2. CPI = 3.2 d) Using the total cycles Obtain the execution time. e) Using the average cycles per instruction obtain the execution time. f) Compare the results obtained in parts e and f. 2) Consider the operation of a machine with the data path of the following figure. Suppose that loading the ALU input registers takes m nses, running the ALU takes 12 nses and storing the result back in the register scratchpad takes 5 nsec. If the maximum number of cycle per second in this machine is 50 MHz obtain the m value
