Note: Solve 3

A CPU (Intel Pentium of the early 90s) operates at 25MHz. What is the period of a cycle of the CPU (in ns)? In other words, for periodic ticks, what is the distance in time between two consecutive ticks ? Provide the magnitude with the unit of time and select as instructed. \begin{tabular}{l} 25ms \\ \hline 40s \\ \hline 40ns \\ \hline 40 \\ \hline 40ms \\ \hline 25ns \\ \hline 25 \end{tabular} The Pentium CPU of Question 1 executes a complex instruction that requires 1000 cycles. How many ns does the instruction take? Answer must including the appropriate unit. 40000ns 25000ns 25ns 40ns
