Application field for Floating point unit (FPU)

[seeker_123]

Hi ..

can anyone tell me what are the application fields for FPU on FPGA?
I have gone through some docs from which i got that it can be used for some image processing, DSP applications and matrix operations too.

can it be used in field of PCB testing, signal integrity, EMI/EMC or antenna simulation.. or like that?

I don't know anything about these mentioned fields. I just want to know whether it is possible.

So please guide me in that

thanks in advance

You are almost right.
Only difference is that for a PC (simulations/modelling,...), you can have FPU implemented in software or as a co-processor.

thanks hareeshravi
can you provide me some reference paper or link for mentioned field.

Hi,

Plz see this discussion: https://forum.arduino.cc/index.php?topic=142929.0

FPU is used for calculation, where high calculation accuracies are must.

So if you have to do an operation like 4.5679 * 3.2289, How will you implement it?
Here is where IEEE 754 standard for Floating point representation and computation helps us.
It is basically a method by which decimal digits can be represented and calculation can be done in a digital world.

Now how and when to use it is up to you.
Not all operations with decimal digits opt for floating point, as it requires a pretty heavy hardware.
