Is there some kind of semi-high level overview of the structure of Dolphin somewhere?

Been looking through the source code and I'm seeing room for improvement in the way asynchronous dispatch occurs, but I'd like to get a high level overview of how the whole system works before I start trying to change anything. Is there a high level overview of the different components and how it fits together somewhere?

Oh, I doubt there is one. I'm sorry. We have lots of in-detail articles, but the general overview is missing. I think the best way is to ask on our IRC channel: #dolphin-dev @ freenode.

Which "asynchronous dispatch" are you talking about? GPU dispatching, audio output, real controller feedback, ...?

The very short overview: There are some main chips within the Wii:
- the PPC CPU. We use this one as the main one (for eg timing) as the game runs natively here.
- the GPU. We parse the command buffer and execute everything as fast as possible.
- the DSP. It's mostly used for audio processing, and as nobody but Nintendo itself was able to program it, there are only a few programs. So we have reimplemented them in C++. But there is also a low level emulation of the instruction set.
- the ARM CPU. Used for the OS, which is responsible for all kind of IO. Here we emulate only the interface (no LLE available)

anything with a queue and a mutex probably

where can I find some of these articles anyway? thanks for the short overview
