Cavium Networks has unveiled the PureVu CNW66xx, its latest line of SoC video processors for universal wireless display receivers.

According to Cavium, the processor supports a wide range of home networking and wireless video transmission protocols including its WiVu WiFi Alliance 802.11-based wireless display standard (WFD) and DLNA.

Touted as flexible, low-cost and high-performance the PureVu CNW66xx line expands Cavium's wireless display product portfolio.

Unlike the CNW5xxx family, which targets the high-end, fully interactive, 2D and 3D home theater solutions, the CNW66xx processors are designed for very low-cost video streaming wireless display receivers found in portable consumer devices with built-in wireless display functionality. These include portable CE devices such as smartphones, tablets and notebook computers running a software client to enable seamless wireless connectivity with Cavium's CNW66xx based receivers.

The CNW66xx offers up to 1080p performance, a level that exceeds the requirements of most software transmit solutions.

With the CNW66xx, Cavium believes that OEMs will now be able to build a single wireless display adapter that can work with various video and networking protocols. The processor also provides a wireless display link with a wide range of popular portable devices in the market today, according to Cavium.

The processor's key features include multiformat video processing engine capable of decoding up to 1920x1080 p30/i60 resolutions for a wide range of video standards including MPEG2, H.264, MPEG4, AVS, VC-1, and MJPEG; ARM CPU core; programmable audio DSP with advanced DMA functionality to enable real time decoding of popular audio standards including MP3, AAC, and AC3; display processor with multilayer alpha compositor, 2D graphics layer with color key and programmable screen locations, and video layer with 16:9 to 4:3 conversion, letterboxing, pre-scan, and up/down scaling; and video post-processor with 3D motion adaptive de-interlacer and high quality polyphase FIR video scaler.

PureVu CNW66xx system interface features 4 video DACs for YPbPr/RGB, S-video, and CVBS output; integrated HDMI 1.3 transmitter, with DVI support; integrated TV encoder supporting both Standard Definition and High Definition video; I2S and S/PDIF digital audio output; 10/100Mbps Ethernet (MII interface); USB 2.0 high speed host controller (with embedded PHY); and Misc I/O including UART, SPI, I2C, and GPIOs.
