Consider three different processors P1, P2, and P3 executing the same instruction set.

P1 has a 3 GHz clock rate and a CPI of 1.5.

P2 has a 2.5 GHz clock rate and a CPI of 1.0.

P3 has a 4.0 GHz clock rate and has a CPI of 2.2.

a. Which processor has the highest performance expressed in instructions per second?

b. If the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions.

c. We are trying to reduce the execution time by 30%, but this leads to an increase of 20% in the CPI. What clock rate should we have to get this time reduction?

11. Consider three processes P1, P2, and P3, and all them three are ready to run at time = 0. Each process has two CPU bursts. When its first CPU burst is completed, each process requests a blocking I/O operation on a separate I/O device. When a process starts to receive service for I/O, the OS scheduler selects and dispatches another process available at the ready queue. The CPU scheduling policy is preemptive priority-based scheduling, where a process being running...

Rosie’s Company has three products, P1, P2, and P3. The maximum Rosie’s can sell is 76,000 units of P1, 57,000 units of P2, and 45,000 units of P3. Rosie’s has limited production capacity of 42,000 hours. It can produce 12 units of P1, 6 units of P2, and 3 units of P3 per hour. Contribution margin per unit is $5 for the P1, $15 for the P2, and $25 for the P3. What is the most profitable sales mix for...

Consider two different implementations of the same instruction set architecture. The instructions can be divided into four classes according to their CPI (classes A, B, C, and D). P1 with a clock rate of 2.5 GHz and CPIs of 1, 2, 3, and 3, and P2 with a clock rate of 3 GHz and CPIs of 2, 2, 2, and 2. Given a program with a dynamic instruction count of 1.0E6 instructions divided into classes as follows: 10% class A,...
