Note: Solve 2

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 has access to a memory where memory access time is 120ns that is a memory reference such as M[1001] requires 120 ns to get resolved. How many CPU cycles does this correspond to ? 2 4 3 1
