Problème mémoire FPGA

Bonjour à tous,

 

Il m'arrive un problème de mémoire au niveau du FPGA.

 

Je créé un tableau pour créer un sinus dans mon Microprocesseur comportant 1024 points.

J'envoie ces points directement dans le FPGA et donc je fixe le nombre de points à 1024 dans le FPGA.

 

Lorsque je compile le FPGA il m'est dit que je dépasse la mémoire du FPGA à plus de 200%.

 

J'envoie seulement 1024 points...

Hi,

 

Some questions :

What is the reference of the FPGA Card (amout of memory) ?

How did you send the array to the FPGA ?

Can we see the FPGA VI ?

 

And by the way we are in the English section of the forum, it would be good and great for the non speaking french user to repost you question in English.

 

Regards Marc.

Hi,

 

Thank you for your answer.

 

The FPGA Card : https://www.ni.com/en-us/support/model.crio-9074.html

 

Here in part attached pictures of my VI and error.

Hi,

 

2 things for the FPGA :

- I think you should put the while loop inside the case structure

- Use flat sequence in order to generate the output and then wait fonction in the 2 step of your sequence.

 

What is the code in the faulse case of the case structure ?

 

On the Windows VI, add a timming function to avoid full charge of you CPU.

 

Regards Marc
