Alexandra Hájková	2008f76054	dca: remove unused decode_hf function and quant_d tables They were superseded with their integer equivalents. Rename integer decode_hf to decode_hf.	9 years ago
Janne Grunau	90b1b9350c	arm: add ff_int32_to_float_fmul_array8_neon Quite a bit faster than int32_to_float_fmul_array8_c calling ff_int32_to_float_fmul_scalar_neon through FmtConvertContext. Number of cycles per int32_to_float_fmul_array8 call while decoding padded.dts on exynos5422: before after change cortex-a7: 1270 951 -25% cortex-a15: 434 285 -34% checkasm --bench cycle counts: cortex-a15 cortex-a7 int32_to_float_fmul_array8_c: 1730.4 4384.5 int32_to_float_fmul_array8_neon_c: 571.5 1694.3 int32_to_float_fmul_array8_neon: 374.0 1448.8 Interesting are the differences between int32_to_float_fmul_array8_neon_c and int32_to_float_fmul_array8_neon. The former is current behaviour of calling ff_int32_to_float_fmul_scalar_neon repeatedly from the c function, The raw numbers differ since checkasm uses different lengths than the dca decoder.	9 years ago
Janne Grunau	e2710e790c	arm: add a cpu flag for the VFPv2 vector mode The vector mode was deprecated in ARMv7-A/VFPv3 and various cpu implementations do not support it in hardware. Vector mode code will depending the OS either be emulated in software or result in an illegal instruction on cpus which does not support it. This was not really problem in practice since NEON implementations of the same functions are preferred. It will however become a problem for checkasm which tests every cpu flag separately. Since this is a cpu feature newer cpu do not support anymore the behaviour of this flag differs from the other flags. It can be only activated by runtime cpu feature selection.	9 years ago
Christophe Gisquet	f827a17005	blockdsp: reindent after parameter removal Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Christophe Gisquet	562ba4a827	blockdsp: remove high bitdepth parameter It is only (mis-)used to set the dsp fucntions clear_block(s). But these functions always work on 16bits-wide elements, which make the parameter useless and actually harmful, as it causes all content on more than 8-bits to not use accelerated functions.

Martin Storsjö	b280c6202b	arm: fft_vfp: Unify the behaviour in ff_fft_calc_vfp between arm/thumb Don't include the function pointer table in the code segment in arm mode. This shouldn't have any significant performance effect. It does end up as a few more instructions than before, for ARM, but only at the entry to this function, not within the fft functions themselves.
