Re: MCU and Automotive Questions
FPGA's are pretty handy for designing brushless. DC motor controllers so as hybrid cars gain in the marketplace so may FPGA'S. MicroSemi also does 150 C rated automotive FPGA'S.

Open source Hardware and Security issues
Warren, I can suggest some of the questions related to security aspects of MCU and about open source hardware. I think like me, many of our community members may interested to know about such things.

Blogs through Interview
Warren, I think creating blogs through interviewing dignitaries is a good idea. But make sure that the fellow is speaking on company perspective or technology perspective. Certain peoples may put their own interpretations for company policy and hence it gets diluted.

MCU and Automotive Questions
Hi Warren,
Re: "will be talking to programmable logic "visionaries" to get their views of the future"
Are these FPGA visionaries or FPGA deities? :-)
Here's a couple of market-based questions with respect to MCUs...
1) In the "next five or 10 years", do these visionaries expect FPGA design wins to overtake MCU design wins in the automotive market? Many FPGA companies have automotive families of devices (ex: Xilinx Automotive "XA" including –40°C to +125°C, AEC-Q100 qualification, PPAP documentation, etc.); however, they are still way outnumbered by MCUs in current applications. So, I wonder if they expect for the ratio to remain the same, be more even/split, or FPGAs to overtake MCUs in the next 5-10 years. And, if overtake, what is the strategy to get there...?
2) This one is probably more like 10+ years and beyond, but I will ask anyway. Like the automotive questions above, do the visionaries expect the FPGA and MUC markets to co-exist as is for decades to come or do they expect the market to eventually merge or blur such that it would be an 'all programmable device' market in the future (in other words, no MCUs)?

Re: FPGAs with Optical Interfaces
Going to TC Maker's Hack Factory tonight to work on the LED version. I believe we may see speeds aproaching 100 HZ! I think the phototransistor I am using may be the limiting factor.
Re: Next-Generation Configuration Cells
@Warren: I'm not an expert, but my understanding is that they've been having probs making large amounts of reliable FRAM -- I'm not sure about its speed or power -- I just know that it's been talked about for ages but it never seems quite ready for center stage...
Re: Next-Generation Configuration Cells
Well- you don't want much do you? How about FRAM as a possibility? It hits most of your requirements. Notice the move by Cypress to acquire the technology, probably for PSoC, but Cypress does have some history with programmable logic too...http://tinyurl.com/7mubel5
Re: FPGAs with Optical Interfaces
@EdV: Hi Ed, I recognize your neon optical logic ... so yes, just like this but with an operating frequency of more than 1 Hz (grin)

Would you class these as adages, aphorisms, axioms, dictums, epigrams, maxims, precepts, saws, truisms, or... well, what?
Here we discover how to use the XADC (Xilinx Analog-to-Digital Convertor) in the Zynq All Programmable SoC to read the chip's internal temperature and voltage parameters and output them over an RS-232 link.
When extreme thermal cycling causes circuit boards and chip packages and the silicon die in the packages to expand and contract at different rates, problems may ensue.
In part 3 of this epic tale we consider how we might use tri-state buffers, leading up to the legendary bi-directional buffer.
Digital engineers are often confused among operational amplifiers, differential amplifiers, and instrumentation amplifiers; this is exacerbated by the fact that their circuit symbols can be similar.
