Hi all
Thanks for advices.
I will need time to study all those options.

If no budget and you are mostly a software guy and are doing this because if might be useful if you can get the performance you are looking for, then consider an AWS Cloud FPGA...

Amazon EC2 F1 Instances[^]

No messing with drivers installing tools and and all the other stuff that you have to do before you can do what you want to do. Nicely documented with low slope paths for people coming from a software background. Probably the very fastest and cheapest way to get your algorithm actually running on an FPGA.

And if it does turn out that your new FPGA is useful, you can make an image deploy it on effectively an infinite number of hardware units with a click of the mouse.

depends on your budget.
I bought a few EP2C5T144C8N mini boards through Amazon for under $20 each but you would also need the $10 'Blaster' programming cable. Look up "RioRand EP2C5T144 Altera Cyclone II FPGA Mini Development Board " on Amazon.(free shipping) just connect to 5 volts.
The Software is free from Altera (now Intel) I use Altera Quartus II 13 sp1
I have several 8 bit microprocessor emulator projects I run in them

Live long and prosper

A while back, Michaela Blott of Xilinx was the first I know of to do it all, communications and otherwise, to put a KVS onto an FPGA that handled IP requests at line rates up to 10gbps (and they projected they could do 100gbps with one FPGA node.)

https://www.usenix.org/sites/default/files/conference/protected-files/blott_hotcloud13_slides.pdf

Since then many have repeated this work in conferences, but I believe you can get her code and help if you use a Xilinx FPGA. Nice lady.

So, when the system pops up that "Unknown Error" message, I wonder how it knows it's really an error?

In fact, it doesn't - it said so.

Probably an error message conceived by politicians.

Write a source file fuzzer and see how the compiler deals with it!

Years ago, I was working with a compiler that used to throw the error message "Something wrong".

We had sort of an informal competition to make the shortest source code file that would provoke this error. If I remember right, the winner was down to four lines of code.

I've gotten the C# compiler to give me an internal error. I think I was doing something terrible and unforgivable with generics, admittedly. It has happened intermittently from time to time, but I've only encountered it consistently once.

That's the best I got. I love that you had a contest to confuse the compiler. It's kind of mean though. Poke tongue | ;-P

It would be a lot more surprising if it said "Known error"

"Unknown error" is better than an incorrect result, isn't it?

One way is too check whether the result is in an expected range.

Was making pizza-dough and it failed to rise. So, there was an error but not sure what went wrong. That's an unknown error, no?

No - the error is clearly: you are no cook !
