H.264/MPEG-4 AVC is the loresr coding standaid .jointly developed IJ.V the Video Coding Experts Group IVCEG) of' ITU-T and rhe Moviq Picriire Experrs Group (MPEG) uf ISO/IEC. This puper dacrihes on integrated upplicarion specific silicon hurdwore core which iiiqhnents the 11264 srandurd at Muin Profile wirh support ,/or all broadcusr./iirnmrs lip ro and inchrdiiig high d&irion. The .sohition is highly oprimized and c0nsinne.s less rhan 160 milliwarrs or 200 MHi .fix the decoding of high dc/inirion images or 30,fianies per second 1v17en implemented on 130nm process. The iinplemenfarion requires less rhan 300K gam and 24 MB of e.rternu1 system memory Key feariires inchide a novel and innovarive memory managemenr scheme to reduce the hand~sidtl, IO the moin system inemmy and an optimized single syniholper clock cycle CABAC decoding engine'.
