WAVE420
下一代 HEVC 编解码

Chips&media的WAVE5系列是最佳视频解码器之一,可支持被称为H.265的新一代HEVC标准与谷歌的VP9以及中国标准AVS2多格式的IP。

WAVE5系列是为高端UHD SoC提升性能第二代视频IP。只需500MHz 时钟频率可以解码3840x2160 60fps的视频或同时解码2个3840x2160 30fps的视频,

除4K 60fps 的优秀性能外,WAVE5 系列IP实现了最大带宽效率与出色的低耗电性能。并且使用了 frame buffer compression CFrame技术,平均可降低 50~70%内存访问带宽。

WAVE5 系列可适用于UHD TV,STB,AR/VR,智能手机,平板电脑,摄像机,照相机等高画质的多样化产品中。
