| This is the sort of thing I might ponder, but end up rejecting. Nice to see there are people in the world that reject such notions and just do it for the sake of doing it. |

The perpetrator of this ummmmm... thingy has been seen on avrfreaks recently.

| A pretty cool hack, but I don't think I would actually use it for anything. |

Not the Linux itself but the ARM emulator in this is the real "clever bit" and would act as yet another solution to perennial "how do I run code from RAM/SDCard/whatever?" question. It'd also mean that easy to find/use ARm dev tools (arm-gcc for example) could be used for developing the code. |

I loved this when we all had a look at work - but I'd REALLY love to see it running on the XMEGA, overclocked to 72MHz (the maximum stable speed I was able to get in my own testing with room temperature/3.3V) and the EBI used for faster memory access.

There is a moment in all new technologies when the developer is overcome by massive feeling of despair that results from having spent many, many long hours getting the new technology to do something 'stupid', or to say, something that can be done much cheaper and easier with existing, older technology.
Steven Levy describes this emotion in the book 'Hackers' when he describes the MIT student who spent a hundred hours getting the school's DEC minicomputer to emulate a typewriter.
This overwhelming feeling of despair and worthlessness is in reality a major breakthrough in bringing advanced technology from the lab to the real world. The feeling passes; the tech breakthough remains. And as the technology advances, increases in speed and comes down in price, it creates more wealth in the real world.
Congratulations! |

It could be used to benchmark the compiler and the tools  |

Something created simply because you can is beautiful in its own right; as it serves no practical purpose, it itself becomes something to admire and thus gives itself worth.

Reminds me of Rowland Emett - anyone who doesn't already know his work should Google it. Wonderful stuff. The guy was clearly stark staring bonkers but an utter genius with it! |

If it's any consolation, the Apps team in Norway were going nuts over this the other day. We'd love to see you port it to the XMEGA devices and use the hardware EBI and USART-SPI modules to see how well it performs, if you have the time.

I would sincerely hope that someone in Atmel has already posted some XMegas, programmers, debuggers, adapters, norse figurines etc. in Dmitry's direction?
Is there some Atmel "award of engineering excellence" that can be handed out? |

This reminds me an oil tanker propelled with two short oars.
Seems like the definition of beauty is highly subjective. |

| Snake oil. Show me the code and the schematic for wiring up a ram stick. How do you set 32 address lines and read and write 32 data bits without latches? How do you do row and column refreshes every couple of milliseconds? |

| I'd like to see a schematic and some details about the refresh too. But wasn't it 30 pin SIMM? They have 12 address lines (12 rows x 12 columns) and 8 data lines. |

| I have no idea how ram row and column refresh works. You have a 12 bit counter on the columns and a 1 of 12 code on the rows? |
