A CPU has an instruction pipeline with 10 stages. If a branch misprediction occurs 10% of the time and causes a 5-cycle stall, what is the effective CPI assuming an ideal CPI of 1.2?

Suppose a CPU executes a program in 4 seconds. If the clock speed is doubled while keeping the CPI constant, what will be the new execution time?

A system has a base execution time of 10 seconds. After applying compiler optimizations, the number of executed instructions is reduced by 20%, but the CPI increases by 10%. Assuming the clock speed remains constant, what is the new execution time?

A processor executes a program with the following instruction mix:

• 40% ALU instructions (CPI = 1)

• 30% Load/Store instructions (CPI = 2)

• 30% Branch instructions (CPI = 3)

If the processor has a clock rate of 2 GHz, what is the effective CPI?

If a CPU has a clock rate of 3.5 GHz and an average CPI of 1.8, how long does it take to execute a program with 500 million instructions?

In a system that uses instruction pipelining, if the probability of a control hazard (branch misprediction) is 20% and the penalty for each misprediction is 3 cycles, what is the effective CPI if the ideal CPI is 1.2?

A processor has a cache hit rate of 90% and a memory access time of 100 cycles. If the cache access time is 5 cycles, what is the effective memory access time (EMAT)?

 If a system has an instruction mix with 40% arithmetic, 30% load/store, and 30% branch instructions, and each takes 2, 3, and 4 cycles respectively, what is the average CPI?

A CPU fetches an instruction in 2 cycles, decodes it in 1 cycle, and executes it in 3 cycles. If the system has a pipeline, what is the ideal speedup for executing 100 instructions, assuming no stalls?

A processor follows the Fetch-Decode-Execute cycle. If an instruction takes 5 cycles on average and the processor operates at 2 GHz, how many instructions can it execute per second?
