From c0942b7a2c5ccfd39907257b3b0a10f86d6b9164 Mon Sep 17 00:00:00 2001 From: Shiyou Yin Date: Fri, 1 Feb 2019 14:05:00 +0800 Subject: avcodec/mips: [loongson] optimize put_hevc_epel_bi_hv_8 with mmi. Optimize put_hevc_epel_bi_hv_8 with mmi in the case width=4/8/12/16/24/32. This optimization improved HEVC decoding performance 1.7%(2.30x to 2.34x, tested on loongson 3A3000).
