Hmm, I wonder if it would be possible to make a 32-bit intel-based RasPi-type thing out of these? Sounds interesting.

I feel you. I only use C when absolutely necessary, and even then minimally. I would rather use something like Python if I wanted something that high-level to be quite honest. EDIT: Yes, I know Python is interpreted and not usually compiled. In that interpreted environment, however, I would expect about the same amount of overhead/wasted CPU cycles as that disassembled C code, or possibly more. If you wanna be inefficient it's better all than none  [/quote] |

I am trying to get a Quark SE C1000 dev board. That one seems to have 80k RAM and 192k * 2 of ROM, etc.
I usually like to use assembler too. But it appears that this thing doesn't come up in protected mode at all - I think you have to put it there yourself. As soon as I get one of them, I'm going to make a commercial product out of one. |

Except you do not have to set up anything. And some people might not realise that the so-called "16-bit" version of 32-bit unreal mode is just as good. All 32-bit registers and 32-bit addressing modes are available, just a few extra size override bytes in the code, but more often than not other factors result in binaries that are very similar in size. I call it 32-bit Flat Real Mode, and my hobby OS FAMOS is based on it. I just googled the Quark SE C1000 and I get the impression Intel developed it as part of the chipset support for their "main" CPU's - for power management mainly. Although I'm not sure what they mean by "the edge" here? http://www.intel.eu/content/www/eu/en/embedded/products/quark/mcu/se-soc/overview.html _________________ FAMOS - the first memory operating system |
