What unit is used to measure CPU speed?
Pritesh R.
21. Challenge The processing speed of a computer refers to the number of binary operations it can per- form in a second. Thus, the processing speed is actually a frequency. If the processor of a personal computer operates at $1.80 \mathrm{GHz}\left(1 \mathrm{GHz}=10^{9} \mathrm{~Hz}\right)$, how much time is required for one processing cycle?
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 10 GHz. Furthermore, 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. Please show your detailed work! Thank you.
