Generating signal with several frequencies - Timing issues

Hi

I use Labview 7.1.

I am trying to generate a signal composed of 1000 different frequencies.

For this purpose I am using the Multitone Generator VI .

 

My problem is that the generating process is too long for my real-time application.

 

Is there any way to accelerate (optimize) this process?

I think about several options, such as:

Using more powerful computer (multicore)

Making the process parallel (is it relevant for Labview7.1?)

Changing VI's properties (priority etc..)

 

Please advice

Can you post some code? A trick may be to only update data that change in each iteration.



Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

Hi,

 

Attached my problem.

 

I am trying to generate signal with 100 frequency component (100 different sine waves).

According to the timers it is taking 87mSec to produce the signal which length is 1 second.

 

In my project, I need to generate 1000 frequency components. And also 20 channel of this kind.

 

So it is clear that i will not be able to achieve the timing requirements

(It will take more than 1 second to generate a signal of 1 second)

 

What can you advise me ?

Thanks

 

Amir

How about posting your full code. we can not debug picture 😉

OK

 

Here is the code.

 

It is rather simple,

I am just  trying to improve timing of this basic module in order to duplicate it and then to fit it into the limited time frame i need.

 

Thanks,

Amir
