ChipWrights Updates Software for IP Camera Market
ChipWrights announced the latest software release for the IP camera market. The software includes improvements to their DSP libraries and Linux support. It’s now possible to implement a dome fish-eye (360 degree) camera with dewarping and filtering functionality. The software release includes the necessary components to implement cost-effective IP cameras using the CW5631 System-on-Chip, and complements ChipWrights’ initial software release for IPTV media player applications.
Linux 2.6.29 Kernel Improvements
- DSP firmware load support
- Faster SD driver with SDIO support
- SDIO Wi-Fi support through libertas driver
- Booting and rootfs in NAND flash with JFFS2
- Improvements to various device drivers
- Video capture support (V4L2) for various video sources, enabling users to easily port video capture applications to the CW5631 System-on-Chip
Application Support Highlights
- Qt 4.5 support
- DSP acceleration of Qt applications via an SDL driver layer
- Mplayer built with V4L2 support for live playback of captured video
- Standalone FFMPEG (libavcodec) with DSP accelerated encode and decode for supported codecs
- MTD utils for NAND flash support
- Support for WPA/WPA2 Wi-Fi connections
- DSP video processing showcase with PC-based GUI and live video capture using V4L2
- Real-time DSP processing including, de-interlacing, de-warping, filtering, chroma-key, picture-in-picture, and live RTP streaming of MPEG4 encoded video using FFMPEG/Live555
Other key improvements include NAND boot loader bundled with u-boot (u-boot-2009.01), which enables running the root file system from flash and eliminates the need for additional storage media (such as an SD card or a hard drive) to run the whole system. Plus, a sample IP Camera application with a PC-based GUI shows most features.
The CW5631 System-on-Chip is ideal for IP cameras and IPTV set top boxes. It is an embedded single-chip solution designed for multi-purpose applications that require high-speed digital video processing, small size, and low power consumption.
