Questions

Q$\mathrm{.}1$: answer the following questions.

The clock cycle time that equals $120$ picoseconds $($ps$)$ is equal to in millisecond $($ms$)$ and to in second $($s$).$

The clock rate that equals $4\mathrm{.}5GHz$ is equal tc in $kHz,$ and to in $Hz.$

Computer A has a $2\mathrm{.}5GHz$ clock rate and $25ms$ CPU time.

a$.$ Calculate the clock cycle time?

b$.$ Calculate the CPU clock cycle

Suppose you wish to run a program $P$ with $5^{**}{10}^6$ instructions on a $500MHz$ machine with a CPU time of $20ms.$

Calculate the CPI.

Two processors, $x$ and $Y$ have clock frequencies of $3GHz$ and $4GHz$ respectively. Suppose $x$ can execute an instruction with an average of $1\mathrm{.}5$ steps and $Y$ can execute with an average of $2\mathrm{.}5$ steps. Considering the same IC$,$ which processor is faster and by how much?
