1 billion instructions =10^9 instruction
2ghz =0.5 *10^(-9) sec
Cpi =(50*3/100)+(30/100*4)+(20/100*5)
=1.5+1.2+1=3.7
Execution time =3.7* 10^9 *0.5 *10^(-9)=3.7*0.5=1.85sec

A program (or a program task) takes 150 million instructions to execute on a processor running at 2.7 GHz. Suppose that 50% of the instructions execute in 3 clock cycles, 30% execute in 4 clock cycles, and 20% execute in 5 clock cycles. What is the execution time for the program or task? Suppose the processor in the previous question part is redesigned so that all instructions that initially executed in 5 cycles and all instructions executed in 4 cycles...

5. If a processor clock ticks 4 billion times in a second and has a frequency of 1.5 GHz, with each clock tick, one or more instructions may complete, if a program runs on 3 GHz processor for 7 seconds, how many clock cycles did it run for? (10 points) If a program runs for 2 billion clock cycles on a 1.5 GHz processor, what is the execution time in seconds? (10 points)

A program executes 10 billion instructions. It executes on an Intel processor that has an average CPI of 1.5 and a clock frequency of 2 GHz. How many seconds does the program take to execute? What is the cycle time of this Intel processor? Assume that an AMD processor takes 6 seconds to execute the program. What is the speedup provided by the Intel processor, relative to the AMD processor
Suppose this program is executed in a computer in which the clock rate for the processor is 1.6 MHz
Figure 1: each block gives the number of different types of instructionsConsider a program with the execution flow shown in Figure 1. There are in total 3 types of instructions used in this program: Type 1 (in-processor calculation): execution rate as 1 per clock cycle; Type 2 (memory access): each instruction takes 2 clock cycles for execution; Type 3 (loop control): each instruction takes 2 clock cycles for jump into the loop block or 3 clock cycles for jump to the block after...

Need help to answer this question with explanation please. A program is made of 40% arithmetic instructions (each takes 5 clock cycles), 30% branch instructions (each takes 2 clock cycles) and 30% data transfer instructions (each takes 12 clock cycles). The program has 20,000 instructions and is running on a CPU with a 3 GHz clock. Find the execution time.

Suppose the processor in the previous example is redesigned so that all instructions that initially executed in 5 cycles now execute in 4 cycles. Due to changes in the circuitry, the clock rate has to be decreased from 2.0 GHz to 1.9 GHz. What is the overall percentage improvement?

A non-pipelined processor has a clock rate of 1 GHz and an average instruction takes 9 cycles to execute. The manufacturer has decided to design a pipelined version of this processor. For this purpose, the instruction cycle has been divided into five stages with the following latencies: Stage 1 – 2.0 ns,Stage 2 – 1.5 ns, Stage 3 – 1.0 ns, Stage 4 – 2.6 ns, Stage 5 – 1.9 ns. Each stage will require an extra 0.4 ns for...
