All Silicon IP

Overview

Chips&Media's WAVE515 is one of the most advanced hardware video decoder IP core which supports the next generation HEVC(High Efficiency Video Coding) standard known as H.265, Google's VP9, and Chinese AVS2 with optimized size.

The WAVE515 is the 2nd generation video IP which is enhanced performance for high-end UHD SoC. It requires only about 380MHz clock frequency to decode 3840x2160 60fps video or 3840x2160 30fps two channel videos with different video standards.

In addition to its superior 4K 60fps performance, the WAVE515 also provides maximum bandwidth efficiency and exceptional low power consumption, which are today's most demanding requirements across all connected devices. It employs frame buffer compression technology named CFrame which can save on average 50~70% bandwidth access to memory.

The WAVE515 is suitable for applications across various industry segments including ultra high-definition televisions(UHDTVs), set-top boxes(STBs), VR?ARs, smartphones, tablets and any others with super-high resolution.
