a_sh-v [17]

Answer:

Achieved Instruction per cycle rate is $4.11\times 10^{15}$

Solution:

As per the question:

Execution time, t = 1.4 s

No. of instructions being executed, n = 1.8 billion =

Clock speed of CPU, f = 3.2 GHz = $3.2\times 10^{9} Hz$

Now, to calculate the actual issue rate achieved:

CPI (Cycle per Instruction) = $\frac{t}{n\times f}$

CPI = $\frac{1.4}{1.8\times 10^{6}\times 3.2\times 10^{9}}$

Instruction per cycle is given as the reciprocal of CPI:

Instruction per cycle = $\frac{1.8\times 10^{6}\times 3.2\times 10^{9}}{1.4} = 4.11\times 10^{15}$
