mova m13, [ana_matrix_rq + 0] movq m15, [ana_matrix_rq + 16] pshufd m10, m13, q0000 pshufd m11, m13, q1111 pshufd m12, m13, q2222 pshufd m13, m13, q3333 pshufd m14, m15, q0000 pshufd m15, m15, q1111 Will probably be faster. Also, you're not using m7 anywhere, and m13, m14 and m15 remain unused after the init code. You could keep four of the coeffs in them instead of using stack. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
