Discussion Overview

The discussion revolves around the accuracy of a clock cycle calculation for a CPU operating at 2.5 GHz. Participants are examining the relationship between frequency and period, specifically focusing on the calculation of clock cycles in nanoseconds.

Discussion Character

  • Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant states that a nanosecond is 10^-9 seconds and presents a calculation for the clock cycle at 2.5 GHz, suggesting it results in 2.5 nanoseconds.
  • Another participant points out that a 1 GHz frequency corresponds to a 1 ns period and implies that a higher frequency should yield a smaller period, questioning the calculation method used.
  • A third participant inquires whether the calculation is related to schoolwork, indicating a potential educational context.
  • Another participant emphasizes that the period is inversely proportional to frequency and notes the absence of a division operation in the original calculation.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the accuracy of the initial calculation, with multiple viewpoints regarding the correct approach to determining the clock cycle period.

Contextual Notes

The discussion highlights potential misunderstandings regarding the relationship between frequency and period, as well as the mathematical operations involved in the calculation.

Who May Find This Useful

TL;DR
What is the duration of a clock cycle (in nanoseconds) for a CPU running at 2.5 GHz?
So far I have come to the understanding that a nanosecond is one billionth of a second or 10-9 seconds. So I found this formula to calculate the clock cycle in nanoseconds, for a CPU running at 2.5 GHz.

10^-9 x 2.5 x 10^9 = 2.5 nanoseconds

Am I missing any important steps with my calculation? Is this accurate?

A 1GHz frequency would be 1ns period. A higher frequency would involve a smaller period. What formula are you using?

Also, is this for schoolwork?
 
Period is inversely proportional to frequency. I don't see the 'devide' operation in your calculation.
