; Notes: filter_block1d_h6 applies a 6 tap filter horizontally to the input pixels. The
|
|
; input pixel array has output_height rows. This routine assumes that output_height is an
|
|
; even number. This function handles 8 pixels in horizontal direction, calculating ONE
|
|
; rows each iteration to take advantage of the 128 bits operations.
|
|
;
|

; This is an implementation of some of the SSE optimizations first seen in ffvp8
