A Question For Dolphin Coders

[metalnumb]

I Have some technical questions in my mind !

I have no interest in coding i just want to learn some concepts

-- if the DSP on thread will let the sound be emulated on a thread , i.e a cpu core <assuming no HT> ,
so what about the emulated GPU and CPU . . . are they going to be emulated together on the other CPU core "because dolphin only uses two cores"?

another question..

-- about the new OpenCL ... how this can lead to faster emulation ? i mean does it make the GPU handle some of the emulated CPU and GPU workload ?
how the graphics rendering on the same real GPU is affected ?

Thanks in Advance . . .

I don't think you understand what dolphin does, either that or I don't understand what you're trying to ask, either way I'll just explain it. At the moment CPU emulation is done on the first thread and the gpu/dsp plugins run on the second. DSP lle on thread gives the dsp lle plugin its own thread, so dolphin uses 3 cores when that option is being used, however you must keep in mind that it only works with lle emulation. In other words with this option dolphin is capable of using three threads but under normal circumstances only uses 2 since no one wants to use lle emulation for audio (you can't really blame them). DSP LLE on thread has syncing issues because if the dsp and gpu plugins are not running on the same thread it is difficult to keep them in sync with each other.

-- about the new OpenCL ... how this can lead to faster emulation ? i mean does it make the GPU handle some of the emulated CPU and GPU workload ?

Once again I don't understand what your asking so I'll just explain what opencl is. Dolphin originally used a texture decoder that was written in C++ and ran on the cpu to decode textures. Opencl is an api/language for writing programs that run on the gpu instead of the cpu. They wrote a new texture decoder with opencl that would run on the gpu instead of the cpu. The old C++ texture decoder still exists and the opencl option merely toggles which texture decoder you're using. It won't necessarily give you any speedup, it just changes whether texture decoding is done on the cpu or gpu. It may reduce loading time in games but in exchange games will take longer to boot since it compiles at runtime.

how the graphics rendering on the same real GPU is affected ?

I do not understand what your trying to say/ask here.

Thanks For The Information ! Actually That's Exactly What i needed and sorry if i couldn't explain my questions well third question is meaningless after your explanation , so never mind !!
