Subject: Re: [FFmpeg-devel] [PATCH 1/6] lavc/pixblockdsp: rename unaligned R-V V functions
Date: Sat, 28 Oct 2023 11:22:13 +0300
Message-ID: <12309088.O9o76ZdvQC@basile.remlab.net> (raw)
In-Reply-To: <20231027192540.27373-1-remi@remlab.net>
P.S.:
It took some additional efforts to get some benchmarks with proto-RVV.
But here they are:
idctdsp.add_pixels_clamped_c: 259.5
idctdsp.add_pixels_clamped_rvv_i64: 90.5
idctdsp.put_pixels_clamped_c: 186.5
idctdsp.put_pixels_clamped_rvv_i64: 65.5
idctdsp.put_signed_pixels_clamped_c: 209.5
idctdsp.put_signed_pixels_clamped_rvv_i64: 61.5
diff_pixels_c: 177.0
diff_pixels_rvv_i64: 72.0
get_pixels_c: 114.2
get_pixels_rvi: 96.2
get_pixels_rvv_i64: 62.0
The old code can't run on proto-RVV, so comparison before/after patchset is
not possible.
