Stella designs a 3 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of 1.5. Sam is tasked with designing the company's next-generation processor and she comes up with an idea that improves the CPI of A to 1.25 and the CPI of B to 1. But the processor can only be implemented with a cycle time of 0.5 ns. Does Sam's new processor out-perform Stella's processor on program A? How about on program B

You are part of the CPP team tasked with designing a new processor. This processor operates at a clock speed of 200 MHz. You have the following hypothetical instruction frequencies for Benchmark B and the number of cycles these instructions take: ⚫ Instruction Class A: 50% of instructions, 1 cycle each ⚫ Instruction Class B: 30% of instructions, 2 cycles each ⚫ Instruction Class C: 20% of instructions, 3 cycles each Assuming the processor executes one instruction at a time, what is the average cycles per instruction (CPI) for this processor with the given mix of instruction classes? 1.7 CPI 2.5 CPI ○ 1.5 CPI ○ 2.0 CPI

Suppose two CPU A and B have exactly the same circuits, but different clock frequencies. Answer the following questions: a) If the clock frequency of CPU A is 8MHz, how long is one clock cycle of CPU A? b) If the CPU A can execute 0.4 million instructions per second on average, how long is the average time to execute one instruction? c) What is the average number of clock cycle to execute one instruction for CPU A? d) The frequency of CPU B is 12MHz. What is the average number of instructions that can be executed per second?

Consider a CPU that operates with a data transfer rate of 30 Mbytes/s. The data is transferred byte-wise and the CPU has to transfer 30bytes of data, and the size of the Status register is 4 bytes. What is the total time needed to perform the data transfer?
