james.jdunne	134fca9b82	~68% increase in GX_TF_IA8 decoding speed. Not an oft-used texture format. An example use is the Wii cursor in MKWii in the menus. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6699 8ced0084-cf51-0410-be5f-012b33b47a6e	2010-12-31 10:20:43 +00:00
james.jdunne	343e3f7c75	~80% speed improvement in decoding GX_TF_I8 textures. Yes, EIGHTY PERCENT. However, for MKWii movie playback I still can't break the fluffin' 48 FPS boundary on my machine! There's something else at play here because this decoder is ridonkulously fast. ~25% speed improvement in decoding GX_TF_RGB5A3 textures which aren't used very much. I thought it would help for movie playback but I misled myself. Video playback has nothing to do with this texture format. Next I'll see if I can knock out some of these other texture decoders. Byte swizzling I'm sure can somehow be accomplished using _mm_unpacklo_epi8 trickery, so that'd be another big win I hope. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6698 8ced0084-cf51-0410-be5f-012b33b47a6e	2010-12-31 07:23:17 +00:00
james.jdunne	b038df64bf	TextureDecoder.cpp: new SSE2 optimized GX_TF_I8 decoder. Probably not ultimately optimal SSE2 code, but provably better (on my machine) than the memset version. Tested with __rdtsc counts in an independent project. I get about 6-7 FPS more on average during the intro movie playback in Mario Kart Wii. Hope this compiles for GCC okay. TextureDecoder.cpp: merged two functionally identical decode5A3RGBA and decode5A3rgba methods. OpcodeDecoding.cpp and DLCache.cpp: optimization for GX_LOAD_XF_REG. The PSUHFB solution sounds better for SSSE3, but this is a small win for the default case. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6692 8ced0084-cf51-0410-be5f-012b33b47a6e	2010-12-30 19:17:08 +00:00
