Abstract
This paper presents a unified 6-D vision processor
that enables dense real-time 3-D depth and 3-D motion perception
at full-high-definition (1920 × 1080, FHD) resolution. The pro-
posed design implements a neighbor-guided semi-global matching
(NG-SGM) algorithm to unify the s tereo depth and optical flow
matching problem and to reduce computation by 98% compared
with the original SGM. We introduce a new custom-designed,
high-bandwidth coalescing crossbar circuit that automatically
coalesces redunda
