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.
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.
