I'll write a history of the emulator to the best of my knowledge for everybody to look at! Hopefully those who have been here longer (like bositman) can fill you in a bit more on what happened. My apologies for any inaccuracies, I didn't join the team until version 0.8.0 (January 2005)! So, here goes..... http://www.pcsx2.net/blog.php#h138189 http://www.pcsx2.net/blog.php#h138189 Thu, 07 Oct 2010 12:19:27 +0000 As most people probably know, PCSX2 is primarily a dual-thread application. The two main threads are described as such: http://www.pcsx2.net/blog.php#h135140 http://www.pcsx2.net/blog.php#h135140 Tue, 14 Sep 2010 13:14:01 +0000 Over the past two years I have become dearly intimate with Microsoft's Visual C++ 2008 compiler, and the methods it uses for optimizing code. Now generally speaking MSVC 2008 does well -- very well -- especially for everyday "not-so-clever" code. Its global optimization feature (aka Linktime Code Generation, or LTCG) is also a tremendous advantage over GCC -- though GCC is in the process of (finally!) adding LTCG to their own C/C++ compiler. MSVC does have a few very annoying failings as an optimizer, though. The most glaring of which has to do with templated code and inlined functions. http://www.pcsx2.net/blog.php#h132830 http://www.pcsx2.net/blog.php#h132830 Tue, 31 Aug 2010 05:08:41 +0000 For those who don't know, DMA stands for Direct Memory Access, and it refers to logic circuits in a computer that allow for the automated transfer of system memory to and from peripherals. DMAs are beneficial because they are simple circuits that do work in parallel to the CPU -- while a DMA transfers data, the CPU is free to do other work.that requires more complex computations and logic. The end result is better utilization of the computer's maximum memory transfer bandwidth and computational/logical ability.
