Then we can add how many microinstructions each takes (\textbf{bold} number) multiplied with how many times it is used. \begin{equation} - \underbrace{\mathbf 1 \cdot 4}_{MAIN} + \underbrace{\mathbf 5 \cdot 2}_{ILOAD} + \underbrace{\mathbf 3}_{IADD} + \underbrace{\mathbf 6 \cdot 2}_{ISTORE} = 29 + \underbrace{\mathbf 1 \cdot 4}_{MAIN} + \underbrace{\mathbf 5 \cdot 2}_{ILOAD} + \underbrace{\mathbf 3}_{IADD} + \underbrace{\mathbf 6}_{ISTORE} = 23 \end{equation} Then we can multiply with the nanoseconds a single instruction takes \begin{equation} - \frac 1 {2.5 \cdot 10^9} \cdot 29 = 11.6 \cdot 10^{-9}\,, + \frac 1 {2.5 \cdot 10^9} \cdot 23 = 9.2 \cdot 10^{-9}\,, \end{equation} -which is 11.6 Nanoseconds. +which is 9.2 Nanoseconds. |
