Abstract

This paper presents an HD720p 30 frames per sec H.264 intra encoder operated at 61MHz with just 72K gate count. We achieve the low cost and low operating frequency with the highly utilized variable pixel scheduling, and a modified three-step fast algorithm. Thus, the resulted design only needs half of operating frequency and reduces 30% of area cost compared to the previous HD720p intra encoder design.
