getting data on and off chip? Lots of Giga Flops don;t matter much if you can't get data to and from the chip...

@Max: "I woudl love to see this if you do it."

You know you'll be one of the first to be informed about this if I managed to do that ;-)

@Garcia: I was planning to build this system by using the fixed-point arithmetics DSP slices already present in FPGA... but the Altera announcement about true Hard-FP supposes a huge inflection point!

I woudl love to see this if you do it.

A QFT (Quantum Field Theory) model simulation implemented in hardware. I mean, not a custom hardware accelerator for a software algorithm, but a pure HW representation of the QFT equations.

You can imagine the space-time mattress and existing Quantum Fields as a set of discrete data points (registers) interconnected with their neighbours by extremely simple logic+math structures (data-paths). Indeed, this "hardware lattice" point of view is as real as the pure mathematical one: the model predicts the same outcomes.

@Garcia: I've been planning a cool experiment since the first time I heard about Altera devices boasting hard floating point DSP slices... too cool!

What experiment?

I cannot wait, I NEED to give a test drive to one of those "big boys" ;-)

I remember when the first FPGAs hit the street in 1985 -- containing little more than an 8 x 8 array of lookup tables. Who would have thunk that one day these little scamps would be boasting myriad hard floating-point DSP cores?
