HD video chip gains Linux development framework support
2010-03-18 Article Rating:  / 0
Timesys announced that its LinuxLink development framework for custom embedded Linux devices supports the Texas Instruments (TI) TMS320DM365 DaVinci video processor. The LinuxLink for DM365 service offers Linux development tools and a pre-integrated build environment for the ARM-based chip, says Timesys.
The LinuxLink for DM365 development service and toolsuite supports TI's Linux-ready digital video software development kit (DVSDK) for the DM365 processor, exploiting TI's value-add video acceleration and codecs, including H.264 and MPEG-4, says Timesys. LinuxLink also provides the Linux GStreamer framework, enabling developers' Linux applications to take advantage of hardware video acceleration in their value-add code, says the company. With a LinuxLink subscription, those developing for the DM365 processor can integrate open source code, media playback frameworks and applications, and GUI frameworks, including Qt Embedded, says Timesys. LinuxLink's desktop version of its "Factory" build framework enables integration of third-party packages, custom applications, and proprietary software, including TI's DVSDK, says the company. 
LinuxLink provides the recent 2.6.32 Linux kernel, which is said to
offer support for many of the device drivers available with TI's DM365
evaluation module (EVM), pictured at left. These are said to include
Ethernet, Flash, LCD, McBSP, TV in/out, and USB. LinuxLink development
software includes the Eclipse-based TimeStorm IDE, as well as commonly
used debugging tools compatible with TI processors, says the company.
(For more details on LinuxLink, see yesterday's story about LinuxLink
support for Wintegra WinPath3 processors, here.) TI's DM365 TI's TMS320DM365 processor began sampling a year ago, billed as a higher-end version of TI's sub-$10, 720p-capable TMS320DM355 DaVinci processor. Timesys, which bills itself as the "preferred Linux solution provider for Texas Instruments processors," released its LinuxLink for the DM355 package last May.
As usual with DaVinci processors, the SoC is available with a Linux-ready evaluation kit and SDK. The DM365 has appeared in a number of IP camera products, including the DM365 IP Camera Design from TI and Appro Photoelectron (pictured above, at right). Stated Sonia Ghelani, TI's DM3xx marketing manager, "By offering LinuxLink support on TI's DM365 DaVinci video processor, this innovative solution allows developers to leverage the video acceleration and codec support needed for video applications, including H.264 and MPEG-4." Stated Maciej Halasz, Director of Product Management at Timesys,
"LinuxLink is well-suited for building Linux products for target markets
for which the TI processor is designed, such as digital picture frames,
DVRs, media players and surveillance systems." Availability LinuxLink for DM365 is available now, says Timesys. For a limited time, developers can obtain free trial access to LinuxLink, to quickly configure, build and evaluate embedded Linux on the DM365 processor, by registering here, and entering promotion code PRDM365.

Aimed at media playback and camera-driven applications, the newer DM365 processor is touted as displaying 1080p video, even with the demanding H264 codec. It supports H.264 high, main, or base profiles at D1 rates (720p at 30fps or 1080p at reduced frame rate) with tri-streaming support, says TI. Equipped with a 300MHz ARM926EJ-S core, plus multiple on-board peripherals, the DM365 also offers TI's fifth-generation ISP (image signal processor), which is said to enable video stabilization, face detection, and other video quality enhancements.
