Comment Re:Arduino in FPGA? (Score 1) 144

Well, sure, but I have no idea why you would want to pay for that privilege. The Zynq is in a totally different weight class: dual 800MHz ARM9, DDR2/3 interface, gigabit tranceivers, 1Msps ADCs. All this hardware to replicate the functionality of a 20MHz 8-bit AVR? Why?

Comment Re:Layman Fusion Technologist (Score 1) 65

I'll add that "science has generated net positive fusion" is not true. He's probably thinking of JT-60, which achieved conditions where, if deuterium/tritium (DT) had been used as the fuel, it would have meant breakeven. However JT-60 doesn't have tritium handling facilities, so they can only use deuterium and extrapolate to DT's higher cross section. Still, it's a remarkable achievement.

In my mind, the biggest obstacle to fusion power is finding/designing materials that will last several years in a commercial reactor. And we have hardly anything at the moment.

Comment Re:Evolving to FPGA (Score 1) 499

I don't see this happening anytime soon. FPGA performance is nowhere near the $/performance ratio that would make sense for the consumer sector. Right now, FPGAs are doing what they've been doing for quite some time: custom logic or glue logic. I see the Atom+FPGA products as aimed toward the embedded space, where applications can benefit from hardware-deterministic timing and customizable interface logic; definitely not for number-crunching purposes.

And in general, FPGAs are only good at very repetitive tasks that can be effectively pipelined. You might have 600MHz performance on paper, but once your design gets complex, the on-chip routing starts to get taxed and becomes the bottleneck. Every successive generation of FPGAs improves on both logic and interconnect, but price/performance ratio and the limited number of applications preclude widespread adoption. And in the meantime, conventional CPUs and GPUs will continue to improve.

The collider and hot fusion people keep saying 'fund us more and we'll get huge energy breakthroughs, but the reality always seems to fall a long way short.

I don't think the collider/HEP folks have ever promised energy breakthroughs; that's not what they're interested in. Collider science is pure science.

The DOE fusion budget, on the other hand, has basically been falling monotonically since the 1970s.

I'd rather just believe that it's done by little elves running around.
