system type and processor speed

[techno di]

hi

processors have speeds like 2.7GHz and this actually a frequency at which it runs ..

frequency is cycles per second .... 2.7GHz = 2.7*1024*1024*1024 = 2,899,102,924.8 Hz i.e cycles per second or pulses per second .

i think 2,899,102,924.8 bits per second such processor is said to process .

on the other hand we have system type like 64-bit ... does that mean processor only processes 64 bits per second ? and how we differentiate both of these factors and distinguish clearly ?

It would be more accurate to think of it as the way the chip handles data and floating-point registers.

I sadly do not actually know the math. It does increase the rate at which data is processed.
It has more to do with the registers though. I'm not sure how it would fit into your equation exactly.

 

[techno di]

you meant that processing speed is dependant of registers ?

 

[Maguscreed]

I suck at explaining this kind of thing.
Just google 64bit computing.
It all seems to be there between wiki and a couple of other sources.

you meant that processing speed is dependent of registers ?

Yes. Think of a Process Register as a bucket. One bucket can hold 32 liters, the other 64 liters. The processor can only send and receive one bucket of information per cycle (whether that bucket is full or not).
Obviously there is an advantage to the larger bucket, but only if it is over half full.

A more intelligent explanation of all of this is here:

The article is old but explains it all better than anything I have seen since.

first let me clear something ,,
difference b/w cycle and pulse ..
computer handles info as bits and bytes , a byte is equal to 8 bits and there are many units like kilo ,mega , giga and tera each a factor of 1024 times more ...
so if we say processor A handles data at rate of 2.7 GHz that will mean this processor handles very huge number of pulses per second ( i mentioned the number in the thread) , in this case it also correct to say it handles the huge number of bits per second as the pulse and bit are same ...

coming to cycle , it is something different , it is the complete revolution of a signal in case it is periodic ... correct me if am wrong

 

[techno di]

in the thread i used cycle and pulse interchangeably though , am confused

 

[TVeblen]

in this case it also correct to say it handles the huge number of bits per second as the pulse and bit are same ...

This is the error in your logic, as "pulse" and "cycle" mean the same thing and do not relate to "bits" directly.

The processor clock cycle refers to the frequency of the transmission.
The bits and bytes refer to the content being transmitted.

 

[techno di]

logic 0 is represented by no signal = no pulse i.e V=0
logic 1 is represented by a pulse i.e V= +ve value

The processor clock cycle refers to the frequency of the transmission.

if u have a wave or signal , cycle is a complete revolution and frequency is #of cycles per second .
freq is measured in Hertz ..

 

[TVeblen]

Fascinating.

 

[Maguscreed]

The frequency is a constant the amount of data processed is not.
Actually these days even the frequency isn't fixed as most chips speed up when the data starts moving in larger amounts.
