LabVIEW NI 7851r DSP Talk

[Alexjdr]

Hi All,

I am programing on a NI PXIe - 1073 system with an NI PXI-7851r board 

I have a question regarding this board, is there a DSP on it ? If there is a DSP, can I program it ?

Any help would be greatly appreciated. Thanks!

Hi Alex,

that board features a FPGA and you can program it using LabVIEW…

Did you read it's specs?

Hi GerdW,

I forgot to mention that it is a board with FPGA. Yes I can program the FPGA. But I found that there is something related to a DSP, some DSP slices.

I need to control the DSP in my project. Is it possible ?

Thank you,

Alex

Hi Alex,

"DSP slices" are part of the FPGA - and you can use them in your FPGA code…

Hi GerdW,

So, this board doesn't have a dedicated DSP? 

Thank you,

Hi Alex,

no, it has a FPGA as written in the spec sheet!

Hi GerdW,

Thank you for clarifying this.

Although the RIO boards do not contain a dedicated DSP, you will find that in the majority of cases the FPGA is actually more capable than an standard DSP because you can customize it to fit any application you need to design. There are designs where a single RIO board replaced a set of 4 or more custom boards using DSPs and had room to spare for additional monitoring, etc. 

I would search around the forums for applications similar to those you are designing and see if others have migrated similar code to FPGA.
