What is the length of a clock cycle in a 4 GHz machine, in picoseconds?
What is the length of a clock cycle in a 4 GHz machine, in picoseconds?
Homework Answers
a 4 GHz processor performs 4,000,000,000 clock cycles per
second, so length of clock cycle will be:
1/4,000,000,000 in seconds
= 
for clock cycle In picoseconds, it will be:

A non-pipelined processor has a clock rate of 1 GHz and an average instruction takes 9 cycles to execute. The manufacturer has decided to design a pipelined version of this processor. For this purpose, the instruction cycle has been divided into five stages with the following latencies: Stage 1 – 2.0 ns,Stage 2 – 1.5 ns, Stage 3 – 1.0 ns, Stage 4 – 2.6 ns, Stage 5 – 1.9 ns. Each stage will require an extra 0.4 ns for...

Plz help me with this question
Consider a 2.5 GHz 'clock' signal on a circuit board that has the following properties: It is constant at +2.00 V for 0.0083 ns and is zero for the remaining 0.3917 ns of the cycle. What is its rms voltage? Did you use the period of 0.4000 ns when calculating the root of the mean of the square of the voltage?
