How would I start the competition? Start a new thread or... Ill just do that Smile

after I right down the rules, I was thinking 512 byte-1.5k

for example, the lightest hexadecimal/text editor with save/open file added with a 512b OS.

Coddy41: You are welcome to run another competition if you like. However in my experience with these type of things it is usually not very successful to run the same competition twice. You might like to try a different variation or add something new into it to attract peoples interest.

I PMd him a couple of months ago and I didn't get any answer. He was getting a new job so I hope the work absorbed him and that nothing bad had happened to him.

Both, his last post was http://board.flatassembler.net/topic.php?p=50475#50475 (note that there is a big gap of 8 months between that post and the before last post).

I hope that those changes are nothing serious and that he can come back here like old times.

PM's are there for a reason...

However Adam will not get any answer because Decard is "dead".

If you need to take a look try [url] http://web.archive.org/web/*/http://decard.net/ [/url]

perhaps due to intracore interrupt handling to ensure fresh data manipulation: assume 4 cores, each performing one fourth of an arithmetic computation, something like an FFT, for example--maybe a split radix with one core computing radix 2 and a second core radix 4, then a third core to compute the power spectrum, from the previous data, while the fourth core shuttles new data into successive cache memory locations. Overhead from the 4 cores will consume a significant amount of "cpu" time, so that an FFT of fewer than 1024 points may be more efficiently handled with a single core, performing each aspect successively, as a single task.

I would say, that the numbers of cores makes little differance, once the code is set up, but i could be wrong.

Yes, multi-tasking at it's simplest is just saving the state of one program, setting the state of another program, running it till you get the next timer int and keep looping. this can be done in realmode, as well as pmode.
Things to note: with a singal core there is no such thing as real multi-tasking, its really just time sharing, in about 10 years time we will laugh at so called multi-tasking, and just give every program a core or two, Multi-tasking was a good work around, when processors were expensive, but as they get cheaper and multi cores, there will be no need, so you will get multi low end cores.

Also note: Dos TSR is a simple form of multi-tasking .

Just tried NanoOS in DOSBox 0.70 (heh), works! Cool beans.

Anyways, 286s were supposedly meant for multitasking, but I can only guess they mean "task switching" (pause, start something else, pause that, resume ... maybe manually a la MS-DOS' DOSSHELL ??). And the AmigaOS was/is supposedly real-mode but multitasks, right?

P.S. The rumor is that programming for multiple cores gets exponentially harder with every extra core, so if that's true, I doubt we'll really get code optimized into too many for the near future.

I think it should have one with
1. kernel is boot sector
2. you have 2 "extension" sectors

the ext. sectors can be used for anything

meh on my PSP so...
