Subject: [FFmpeg-devel] [PATCH 0/6] RISC-V initial ac3dsp
Date: Thu, 15 Jun 2023 10:36:39 +0000
Message-ID: <20230615103645.25778-1-shenpeiting@eswincomputing.com> (raw)
From: Shen Peiting <shenpeiting@eswincomputing.com>
We optimized the six interfaces of AC3 init by RVV, the optimized
performance was tested on the RISC-V ISA simulator--Spike, and the
results were attached to each commit.

lavc/ac3dsp: RISC-V V ac3_exponent_min
lavc/ac3dsp: RISC-V V float_to_fixed24
lavc/ac3dsp: RISC-V V ac3_sum_square_butterfly_int32
lavc/ac3dsp: RISC-V V ac3_sum_square_butterfly_float
lavc/ac3dsp: RISC-V V ac3_compute_mantissa_size
lavc/ac3dsp: RISC-V B ac3_extract_exponents
