Cavium cuts costs of video processors

The PureVu CNW66xx family of SoC video processors from Cavium Networks have been designed to address the growing market demand for universal wireless display receivers.

The processors will enable receiver designs that can support a range of home networking and wireless video transmission protocols including Cavium's WiVu, Wi-Fi Alliance 802.11-based wireless display standard (WFD), and DLNA.

Unlike the CNW5xxx family which targets high-end, fully interactive, 2D and 3D home theater solutions, Cavium's CNW66xx processors are designed for lower-cost video streaming wireless display receivers targeting portable consumer devices with built-in wireless display functionality. The CNW66xx was architected as a cost-optimized solution with up to 1080p performance and provides a multi-format video processing engine capable of decoding up to 1920×1080 p30/i60 resolution for a range of video standards including MPEG2, H.264, MPEG4, AVS, VC-1, and MJPEG.

It has a ARM CPU core and includes a programmable audio DSP with advanced DMA functionality to enable real time decoding of popular audio standards including MP3, AAC, and AC3.

Included are a display processor with multi-layer 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. A video post-processor has 3D motion adaptive de-interlacer and high quality poly-phase FIR video scaler.

The system interfaces include 4 video DACs for YPbPr/RGB, S-video, and CVBS output, as well as an integrated HDMI 1.3 transmitter, with DVI support. The integrated TV encoder supports both standard definition and high definition video as well as I2S and S/PDIF digital audio output. Other interfaces include 10/100Mbps Ethernet (MII interface), USB 2.0 high speed host controller (with embedded PHY) Misc I/O including UART, SPI, I2C, and GPIOs.
