Question 1. (20 Points) On the IAS computer, describe the process that the CPU must perform to read a value from the memory to the AC register and to write a value from AC to memory, explain what will be placed in the MAR, MBR, address bus, and data bus. Question 2. (20 Points) For the IAS computer (Figure 1.6), what is the width in bits for each of the following: MBR, MAR, AC,PC. Question 3. (30 Points) Consider two different machines, with two different instruction sets, Machine A has a clock rate of 300MHz, and Machine B has a clock rate of 270Mhz. The following measurements are recorded on the two machines running a given set of benchmark a. Determine the CPI, MIPS, and the execution time for each machine. b. Comment on the results. Question 4. (30 Points) Consider two computers A and B, A has a single processor of 3.5GHz, and B has 8 cores each of which is 1.5GHz. Both computers use the same instruction set. Assume we have a program to execute in both computers, for the following, which computer is faster? justify your answer. a. 0.1 of the program code can be executed in parallel. b. 0.5 of the program code can be executed in parallel. a. 0.95 of the program code can be executed in parallel
