A 1280x720 pixels 30Frames/s H.264/MPEG-4 AVC intra encoder

Abstract

This paper presents an HDTV size H.264/MPEG-4 AVC intra encoder suitable for DSC and digital video camera applications. The chip reduces the gate count by saving the costly plane mode and enhances the video quality with the improved cost function. With careful scheduling and high performance function unit, the developed chip can easily support 29.46M pixels/s still image encoding and real-time moving picture intra coding of HDTV 720p@30fps video application when clocked at 117.28MHz under 0.18um CMOS process.
