Nintendo wii has one core and dolphin emulator has dual core support at least (speedup).

We can take some separate units onto a separate core, but we can't move the CPU onto a separate core. And the GPU, well, we've got what we've got. Audio is already (mostly) on a separate thread, I thought.

There's still a lot of room for improvements, though, multicore or not.

The audio mixer (and VAG decoder etc) is not running on a separate thread, neither is the Atrac3(+) decoder. When sceSasCore does hleDelay, we could hand off the work to a secondary thread and wait for it to be finished when the sceSasCore hleDelay returns, that'll get us a little bit of parallelism without any chance of anything breaking, I think. Same for any corresponding atrac3 decode function that does hleDelay.

Technicaly speaking, wouldn't things like the texture interpolator (and any quality improving method or anything that has little to do with straight emulation of PSP) be able to be moved to a different thread/core (simmilarly to Dolphin/PCSX2)?
This could speed up quite enough the emulator.

[Henrik]

The texture scaler is already threaded (but could possibly be done in the background while first displaying the unscaled texture, would lead to some annoying jumpiness though).

[xsacha]

Right now for Blackberry and Qt, I have the audio running in a separate thread (the loop that runs NativeMix() ).
Also things like report uploads are on another thread.

Nothing major though.

Apparently we should get benefits from putting GPU on another thread.

[Henrik]

Yeah but NativeMix doesn't do much, it just pops audio off of a queue.

Sounds reasonable for an optional feature. It would look like how games look when you jump between mipmap versions of one texture, not a big deal.

IF you enable cheats on android it wont load any game please fix it

No threadjacking...

Well psp isn't like a wii.

Anyway, Merivex, in my case, I see a big improvement on my htc one (vs my xperia play)...

compatibility then speed ?

Well, the recent commitments are mainly related to video and audio... which is good for both computer and android version of the emulator... since they need to fix things on that side... why would they even care about optimisation for android....

Have a nice day

Yes .. I said, I see there are MANY IMPROVEMENT but not in the PERFORMANCE ^_^ .. ppsspp runs well (always 60-66vps for some games) .. but only after I root my sgs 4 and set the gorverner to performance

[cloud1250000]

ahah sorry I meant in all way... performance, graph and sound.. except a little delay vs the xperia play when playing projec diva

Oohh Yes . . at first I didnt see any improvement in the performance . The problem is fix when I root my sgs4 and set the gorverner to performance(default is ondemand) with no frills cpu .. If u read all the post ,, I already said about this Yes PPSSPP has improve .. but only root user can get the actual speed .. how about other people that doesnt want to root their phone ? ppsspp LAG on unroot device

[xperiaplay2someday]

So I was skeptical about messing with the cpu clock. But I had previously purchased setcpu ( same thing as no frills) But on my galaxy s4 snapdragon. I set it to lock at my highest frequency 1890mhz and it definatly smoother in the games I tried(wipeout pules/initial d)

I also have a widget of my true cpu temp. Right after unlocking irs about 88f after some heavy gaming its 130-140f getting into the redline but that takes a while. With the locked frequency in setcpu it got to 156f after 10mins! That is near the very top of the redline

Alyhough performance is definatly more constant smoothness I uninstalled it. A but too hot for me
