Hello, Changes since version version 5: - Use shifted-add instructions where applicable (pointer arithmetic) to minimise scalar operations to the absolute minimum. - Add AAC PS DSP stereo interpolation [0].
The following changes since commit 7cd252ee41ddc693fa140c5b5eb472b6d6f27f9e: avcodec/parser: Remove declaration of inexistent function (2022-09-24 20:25:19 +0200) are available in the Git repository at: https://git.remlab.net/git/ffmpeg.git rv-cpu for you to fetch changes up to 2f7afca1e160b3bb1bc761ac3eb5e08a0852120b: lavc/aacpsdsp: RISC-V V stereo_interpolate[0] (2022-09-25 17:19:09 +0300) ---------------------------------------------------------------- Rémi Denis-Courmont (31): lavu/cpu: detect RISC-V base extensions lavu/riscv: initial common header for assembler macros lavc/audiodsp: RISC-V F vector_clipf lavc/pixblockdsp: RISC-V I get_pixels lavu/cpu: CPU flags for the RISC-V Vector extension configure: probe RISC-V Vector extension lavu/riscv: fallback macros for SH{1,2,3}ADD lavu/floatdsp: RISC-V V vector_fmul_scalar lavu/floatdsp: RISC-V V vector_dmul_scalar lavu/floatdsp: RISC-V V vector_fmul lavu/floatdsp: RISC-V V vector_dmul lavu/floatdsp: RISC-V V vector_fmac_scalar lavu/floatdsp: RISC-V V vector_dmac_scalar lavu/floatdsp: RISC-V V vector_fmul_add lavu/floatdsp: RISC-V V butterflies_float lavu/floatdsp: RISC-V V vector_fmul_reverse lavu/floatdsp: RISC-V V vector_fmul_window lavu/floatdsp: RISC-V V scalarproduct_float lavu/fixeddsp: RISC-V V butterflies_fixed lavc/audiodsp: RISC-V V vector_clip_int32 lavc/audiodsp: RISC-V V vector_clipf lavc/audiodsp: RISC-V V scalarproduct_int16 lavc/fmtconvert: RISC-V V int32_to_float_fmul_scalar lavc/fmtconvert: RISC-V V int32_to_float_fmul_array8 lavc/vorbisdsp: RISC-V V inverse_coupling lavc/aacpsdsp: RISC-V V add_squares lavc/aacpsdsp: RISC-V V mul_pair_single lavc/aacpsdsp: RISC-V V hybrid_analysis lavc/aacpsdsp: RISC-V V hybrid_analysis_ileave lavc/aacpsdsp: RISC-V V hybrid_synthesis_deint lavc/aacpsdsp: RISC-V V stereo_interpolate[0] Makefile | 2 +- configure | 15 ++ ffbuild/arch.mak | 2 + libavcodec/aacpsdsp.h | 1 + libavcodec/aacpsdsp_template.c | 2 + libavcodec/audiodsp.c | 2 + libavcodec/audiodsp.h | 1 + libavcodec/fmtconvert.c | 2 + libavcodec/fmtconvert.h | 1 + libavcodec/pixblockdsp.c | 2 + libavcodec/pixblockdsp.h | 2 + libavcodec/riscv/Makefile | 11 ++ libavcodec/riscv/aacpsdsp_init.c | 57 +++++++ libavcodec/riscv/aacpsdsp_rvv.S | 286 ++++++++++++++++++++++++++++++++++++ libavcodec/riscv/audiodsp_init.c | 49 ++++++ libavcodec/riscv/audiodsp_rvf.S | 49 ++++++ libavcodec/riscv/audiodsp_rvv.S | 72 +++++++++ libavcodec/riscv/fmtconvert_init.c | 44 ++++++ libavcodec/riscv/fmtconvert_rvv.S | 67 +++++++++ libavcodec/riscv/pixblockdsp_init.c | 45 ++++++ libavcodec/riscv/pixblockdsp_rvi.S | 59 ++++++++ libavcodec/riscv/vorbisdsp_init.c | 37 +++++ libavcodec/riscv/vorbisdsp_rvv.S | 44 ++++++ libavcodec/vorbisdsp.c | 2 + libavcodec/vorbisdsp.h | 1 + libavutil/cpu.c | 13 ++ libavutil/cpu.h | 9 ++ libavutil/cpu_internal.h | 3 + libavutil/fixed_dsp.c | 4 +- libavutil/fixed_dsp.h | 1 + libavutil/float_dsp.c | 2 + libavutil/float_dsp.h | 1 + libavutil/riscv/Makefile | 5 + libavutil/riscv/asm.S | 96 ++++++++++++ libavutil/riscv/cpu.c | 110 ++++++++++++++ libavutil/riscv/fixed_dsp_init.c | 38 +++++ libavutil/riscv/fixed_dsp_rvv.S | 40 +++++ libavutil/riscv/float_dsp_init.c | 72 +++++++++ libavutil/riscv/float_dsp_rvv.S | 238 ++++++++++++++++++++++++++++++ tests/checkasm/checkasm.c | 8 + 40 files changed, 1493 insertions(+), 2 deletions(-) create mode 100644 libavcodec/riscv/Makefile create mode 100644 libavcodec/riscv/aacpsdsp_init.c create mode 100644 libavcodec/riscv/aacpsdsp_rvv.S create mode 100644 libavcodec/riscv/audiodsp_init.c create mode 100644 libavcodec/riscv/audiodsp_rvf.S create mode 100644 libavcodec/riscv/audiodsp_rvv.S create mode 100644 libavcodec/riscv/fmtconvert_init.c create mode 100644 libavcodec/riscv/fmtconvert_rvv.S create mode 100644 libavcodec/riscv/pixblockdsp_init.c create mode 100644 libavcodec/riscv/pixblockdsp_rvi.S create mode 100644 libavcodec/riscv/vorbisdsp_init.c create mode 100644 libavcodec/riscv/vorbisdsp_rvv.S create mode 100644 libavutil/riscv/Makefile create mode 100644 libavutil/riscv/asm.S create mode 100644 libavutil/riscv/cpu.c create mode 100644 libavutil/riscv/fixed_dsp_init.c create mode 100644 libavutil/riscv/fixed_dsp_rvv.S create mode 100644 libavutil/riscv/float_dsp_init.c create mode 100644 libavutil/riscv/float_dsp_rvv.S -- 雷米‧德尼-库尔蒙 http://www.remlab.net/ _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
