People, i have a doubt about dual core mode

[BlackLionPT]

But, about the sound, it runs together with the CPU thread? am I right?

[Iulius]

i'm not 100%sure, but i doubt it.

first : HERE
it is mentioned as own thread

also in main.cpp of dsp_lle (sound) there is a thread created which is called "dsp_thread"

so audio allready has its own thread, but it does not consume much.

Would we get better sound from an option that moves that audio thread to its own core? Or better performance? Even if it's something you can't see, maybe it is a good idea to put in this feature now in anticipation of LLE working.

Just going to clear a few things up. Sound currently runs on the same thread as the CPU. Using HLE sound it takes up about 1% of your processor. We will not move it over to a new thread until LLE sound is finished because LLE sound will NEED it's own thread for emulation because it is so CPU intensive.

unlike HLE sound

Quote:syncronisation is not a big problem, as the 4 cores run at the same speed, and a little bit of typing, we can create something that keeps the cores syncronised.

A little typing? A lil'?

I'd love to see you try.

Put it this way: BSNES and PCSX2 has major problems in speed due in some part to thread sync. The more cores you throw and more threads you do, the harder this gets. And the debugging complexity grows exponentially.

So really, I would love to see you try and do this. There's one thing I cannot stand is people saying "Oh, lets throw a lil code together and it works ^^". Because, it never works that way.

BRAVO. The one thread that makes perfect sense .

Agreed. You have to write the initial code *then* do alot of debugging. Especially for threading.

Technically, the Intel quad core processors are actually two dual core chips on one die, giving a total of four cores

yeah that's true...hmm if only it was possible to make two cores emulate the CPU. 6.12 ghz workin on that should be enough one would think.

Not to be mean, but i'm really pissed off when people multiply clockspeed like that.

YUR SO MEEEEEEEN!!!!! jk. yeah i know its not right, but i wasn't gonna put a random number in that made no sense.

lol guys, it's just a number. Also, I think he meant all the cores joined into one 6.12 GHz core...
