What is clock period of a Processor?

I have a processor of 320 MHz.
What is the clock period of this processor?Or can I clauclate what speed the processor work from this...

It's the same calculation for the period of any repetitive waveform:

period = 1/frequency

In your case, that's 1/320,000,000 or 3.125ns.

T = 1 / F . So if the oscillator vibrates at 320MHz the period T = 0.000000003125 seconds or 3.125 nano seconds...
Keep in mind that when evaluating processor performance - the working frequency hardly tells the whole story. There're many other variables to consider.

The processor (CPU) clock speed is calculated in hertz (Hz), and it reflects the number of cycles per second the processor performs. To calculaate the pwriod use the formular T = 1/f. in your case T = 3.125ns

Are you talking about the processor and his capabilty to works at the maximum speed of 320Mhz
or about the clock witch drives the processor ( value of a Quartz or separate Oscillator).
After the program itsel has a clok periode wich can be less than the main oscillator.
ie: for a PIC16F628-20
external clock maxi is 20 MHz
internal clock is F/4= 5Mhz
so usefull clock periode is 1/5 µS = 200nS

nota: we can try also to force the speed at higher frequency ie: 25Mhz or 40Mhz , but without warranty for results..

for Other microcontroller as 18F46K22 .. etc ..
you have many combinaisons .. and a PLL witch can multiply the Oscillator Frequency
so it is difficult to give a simple response.

As for determining the rate of computations the processor can perform, there are many other variables that come into play. The clock frequency tells you how long it takes to execute one instruction. A simple action like add, subtract, or compare two numbers is generally considered to take one cycle. However it may take a certain processor multiple clock cycles to perform a single function like multiplication or division or two numbers. If you want to gain a lot of insight, take a course that deals with computational design (like low-level FPGA work), and or take a class in Assembly language. Both will give you good opportunities to see how long (how many steps) simple computational activities can take.

When you get into multi-core, multi-threading, look-ahead, pre-caching and predictive algorithms that current CPUs employ, it gets really, really ugly, really, really fast.

My question is for the below requirment.
I am transmitting a signal from a device using an antenna.This device is using 320MHz processor.Transmitted signal will reflect back from target and antenna will recieve the same.Transmission in air will be at the speed of light.Total delay in device is 1 second and total delay in target will be 5 nano seconds.My question is what is the delay required between transmitted and recieved signal, so that device can recognise the recieved signal.My understanding is this is based on clock period or processor speed.Can I measure total time delay using 320MHz processor?Can u throw some light on this?

kemalalturk,

actually i have just registered right now ,i read your question it would be about something i have been through , i know it would be a late answer for your question, but i will tell you that you are supposed to work with four types of delays :
1 -nodal processing :a-check bit errors b-determine output link
2-queueing delay :a-time waiting at output link for transmission b-congestion level of router
3-transmission delay:a- L: packet length (bits) b- R: link bandwidth (bps)
4-propagation delay:a- d: length of physical link b-propagation speed in medium (~2x108 m/sec)

best wishes
