function to generate cosine and sine in FXP in Labview FPGA

Solved!
Go to solution

Dear all, reading a FPGA vi in Labview 8.6 I have found a function to generate cosine and sine in FXP in Labview FPGA,

but I could not understand whether it is a built in function or a subvi.

I attach the icon and explanation .

Does anybody know whether it is a built in function or a vi.

regards

Max

Dear Max Tomatis,

 

 "To generate cosine and sine in FXP in Labview FPGA" it is a built in function.

Dear Enzo,

you are right, there is a built in function to generate Sin in Labview 8.6,

but it is not the same icon as the one  that I have reported in my post.

Do you know if it is possible to find function with the same icon?

Regards

Max

This function is part of the Fixed-Point Math Library from NI Labs.  Beginning with LabVIEW FPGA 2009, it has been integrated into the product, but in versions 8.5 and 8.6, you must download the library and install it into your LabVIEW installation.

Thank you Donovan, I am going to install it ...

I have installed the Fixed-Point library through the setup.exe but I cannot find it from the FPGA block diagram.
Please, could anyone explain me where I could find it from the FPGA block diagram?
Regards
Max

If you don't see the "FPGA interface" like option in the function palette of block diagram you can see in "user library" option.

Hi Enzo, sorry but I do not see the reference to this library. Should I go through the directory tree  or import it from somewhere else?
Thanks

you have to download  .zip file that you want to unzip and place in the following location: 

--> C:\Program Files\National Instruments\LabVIEW 8.6\Targets\NI\FPGA\menus\FPGACategories 

you can proceed with the installer. After you should be like this: 

--> C:\Program Files\National Instruments\LabVIEW 8.6\Targets\NI\FPGA\menus\FPGACategories\Fixed-Point Math\ 

Containing the following .mnu files: 

--> Dir.mnu

--> BasicElem.mnu 

 

And so you should find the fixed-point library  in the palette.

 

Regards,

 

Enzo
