BODA7L
用于中低端产品的多格式硬件解码器IP

Chips&Media的硬件解码芯片BODA7系列是高度优化的高清多格式视频引擎,可解码H.264,MPEG2 / 4,H.263,VC-1,RealVideo,

VP8和AVS格式,分辨率高达 1920x1080和高达40Mbps的比特率。 它在硬件层面上解码CABAC和CAVLC数据的所有工作,

涵盖了所有现有的HD-DVD和蓝光光盘以及所需的预配置解码格式。

 

能够实时处理H.264高性能CABAC / CAVLC解码,高达L4.1,每秒133帧,每秒30帧,BODA7503具有先进的基于多电平时钟门控功能的工具,

可以关闭时钟 当模块空闲时,并且利用MC的内部缓存来节省带宽,从而降低纯带宽。

该核心针对各种高清家庭消费设备,包括HDTV,蓝光DVD播放器,高清机顶盒和媒体盒。
