From 816bd9a7ea4f99aaae67c6e82f686b88dd8c728f Mon Sep 17 00:00:00 2001 From: Robin Watts Date: Mon, 27 Jul 2009 16:29:36 +0000 Subject: Add ARM code version of Normal2x scaler. Add ARM only aspect ratio correcting version of Normal2x scaler. Make WinCE port use Normal2x by default if the screen is large enough. Make WinCE port use aspect ratio correcting version if panel is hidden. svn-id: r42843 --- graphics/module.mk | 3 +- graphics/scaler.cpp | 56 ++++++++++++++ graphics/scaler.h | 3 + graphics/scaler/Normal2xARM.s | 171 ++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 232 insertions(+), 1 deletion(-) create mode 100755 graphics/scaler/Normal2xARM.s (limited to 'graphics') diff --git a/graphics/module.mk b/graphics/module.mk index 90659ce977..46ed564e1e 100644 --- a/graphics/module.mk +++ b/graphics/module.mk @@ -37,7 +37,8 @@ MODULE_OBJS += \ ifdef USE_ARM_SCALER_ASM MODULE_OBJS += \ - scaler/scale2xARM.o + scaler/scale2xARM.o \ + scaler/Normal2xARM.o endif ifndef DISABLE_HQ_SCALERS diff --git a/graphics/scaler.cpp b/graphics/scaler.cpp index 11767848ed..7620e5b107 100644 --- a/graphics/scaler.cpp +++ b/graphics/scaler.cpp @@ -187,6 +187,61 @@ void Normal1x(const uint8 *srcPtr, uint32 srcPitch, uint8 *dstPtr, uint32 dstPit } #ifndef DISABLE_SCALERS +#ifdef USE_ARM_SCALER_ASM +extern "C" void Normal2xAspectMask(const uint8 *srcPtr, + uint32 srcPitch, + uint8 *dstPtr, + uint32 dstPitch, + int width, + int height, + uint32 mask); + +void Normal2xAspect(const uint8 *srcPtr, + uint32 srcPitch, + uint8 *dstPtr, + uint32 dstPitch, + int width, + int height) +{ + if (gBitFormat == 565) + { + Normal2xAspectMask(srcPtr, + srcPitch, + dstPtr, + dstPitch, + width, + height, + 0x07e0F81F); + } + else + { + Normal2xAspectMask(srcPtr, + srcPitch, + dstPtr, + dstPitch, + width, + height, + 0x03e07C1F); + } +} + +extern "C" void Normal2xARM(const uint8 *srcPtr, + uint32 srcPitch, + uint8 *dstPtr, + uint32 dstPitch, + int width, + int height); + +void Normal2x(const uint8 *srcPtr, + uint32 srcPitch, + uint8 *dstPtr, + uint32 dstPitch, + int width, + int height) +{ + Normal2xARM(srcPtr, srcPitch, dstPtr, dstPitch, width, height); +} +#else /** * Trivial nearest-neighbour 2x scaler. */ @@ -210,6 +265,7 @@ void Normal2x(const uint8 *srcPtr, uint32 srcPitch, uint8 *dstPtr, uint32 dstPit dstPtr += dstPitch << 1; } } +#endif /** * Trivial nearest-neighbour 3x scaler. diff --git a/graphics/scaler.h b/graphics/scaler.h index 4cea9ee2fb..bdae161bd1 100644 --- a/graphics/scaler.h +++ b/graphics/scaler.h @@ -45,6 +45,9 @@ DECLARE_SCALER(AdvMame2x); DECLARE_SCALER(AdvMame3x); DECLARE_SCALER(Normal1x); DECLARE_SCALER(Normal2x); +#ifdef USE_ARM_SCALER_ASM +DECLARE_SCALER(Normal2xAspect); +#endif DECLARE_SCALER(Normal3x); DECLARE_SCALER(Normal1o5x); DECLARE_SCALER(TV2x); diff --git a/graphics/scaler/Normal2xARM.s b/graphics/scaler/Normal2xARM.s new file mode 100755 index 0000000000..5de50d9c17 --- /dev/null +++ b/graphics/scaler/Normal2xARM.s @@ -0,0 +1,171 @@ +@ ScummVM Scumm Interpreter +@ Copyright (C) 2009 The ScummVM project +@ +@ This program is free software@ you can redistribute it and/or +@ modify it under the terms of the GNU General Public License +@ as published by the Free Software Foundation@ either version 2 +@ of the License, or (at your option) any later version. +@ +@ This program is distributed in the hope that it will be useful, +@ but WITHOUT ANY WARRANTY@ without even the implied warranty of +@ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
