Consider the evolution of computers in general and the increase in processor speed in particular. Suppose we were to design a system with a processor that is clocked at 10GHz. Further let us suppose that signals in our system can propagate at 80% of the speed of light. Determine the maximum distance between the CPU and Cache memory if we want to access cache data within one processor cycle.

Solution

given, frequency = 10 GHz

speed of signal in our system = 80 % of speed of light = 80/100 * 3* 10^8 = 2.4 * 10^8 m/s

now, maximum distance between the CPU and cache memory = (2.4 * 10^8)/(10 * 10^9) = 2.4 * 10^(-2) m

2.4 cm.

Hope it helps, do give your response.
