Janne Grunau	98fdfa9970	ppc: reduce overreads when loading 8 pixels in altivec dsp functions Altivec can only load naturally aligned vectors. To handle possibly unaligned data a second vector is loaded from an offset of the original location and the data is recovered through a vector permutation. Overreads are minimal if the offset for second load points to the last element of data. This is 7 for loading eight 8-bit pixels and overreads are reduced from 16 bytes to 8 bytes if the pixels are 64-bit aligned. For unaligned pixels the overread is reduced from 23 bytes to 15 bytes in the worst case.	11 years ago

Diego Biurrun	25841dfe80	Use ptrdiff_t instead of int for {avg, put}_pixels line_size parameter. This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic.	12 years ago
Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Ronald S. Bultje	fef906c77c	Move vorbis_inverse_coupling from dsputil to vorbisdspcontext. Conveniently (together with Justin's earlier patches), this makes our vorbis decoder entirely independent of dsputil.	12 years ago
Justin Ruggles	98db4e2a4e	PPC: Move types_altivec.h and util_altivec.h from libavcodec to libavutil This will allow for easier implementation of Altivec functions in libraries other than libavcodec.	13 years ago
Mans Rullgard	4c387c7070	ppc: dsputil: do unaligned block accesses correctly To load unaligned vector data in the usual way, explicit vec_ld() should be used rather than dereferencing a pointer to a vector type. When the VSX extension is enabled, gcc may compile vector pointer dereferences using the VSX lxvw4x instruction instead of the lvx instruction typically used with Altivec/VMX. As the behaviour of these instructions with unaligned addresses differs, it is important that only lvx is used here. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Oskar Arvidsson	19a0729b4c	Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Måns Rullgård	2829ce4b40	Remove PPC perf counter support This functionality is better accessed through tools like oprofile. Originally committed as revision 23808 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	ddb8c2c0f1	PPC: move prototypes to headers and make some functions static Originally committed as revision 22267 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	afe08a728a	PPC: remove unnecessary alignment on local variables Storing a single element from a vector where all elements have the same value does not require an aligned destination. Which element is stored depends on the alignment of the destination address, but since they all have the same value, the result is the same regardless of the alignment. Originally committed as revision 19696 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	76499b9ff1	Remove useless casts of vec_ld() parameters. Gets rid of 'cast discards qualifiers from pointer target type' warnings. Originally committed as revision 18867 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Guillaume Poirier	64adf4f28d	add Altivec implementation of clear_block Originally committed as revision 16078 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	80a61f08d2	Remove AltiVec vector declaration compiler compatibility macros. The original problem was that FSF and Apple gcc used a different syntax for vector declarations, i.e. {} vs. (). Nowadays Apple gcc versions support the standard {} syntax and versions that support {} are available on all relevant Mac OS X versions. Thus the greater compatibility is no longer worth cluttering the code with macros. Originally committed as revision 14366 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
