TI's support features also make system development easier and speeds time to market.
Software support will be available for all major video, imaging, audio and voice compression standards, including, but not limited to, JPEG, motion-JPEG, MPEG-1, MPEG-2, MPEG-4, H.263, H.264, DivX, Windows Media Video (WMV), as well as audio standards such as MP3, Advanced Audio Coding (AAC) and Windows Media Audio (WMA).
Supported voice standards include G.711, G.723.1 and G.726.
The DM270 SoC has the ability to run various operating systems, including Nucleus, Linux, ulTRON, VxWorks and is upwardly code compatible with TI's DSC2x platform.
Additional support for the DM270 includes evaluation models (EVMs), samples, online software module libraries, complete documentation and technical training.
It is also supported by TI's eXpressDSP real-time software technology, which includes the Code Composer Studio integrated development environment (IDE) and the DSP/BIOS real-time kernel.
In addition to supporting a wide array of video, imaging and audio codecs, the DM270 can interface directly with other digital appliances, meeting the need for integration between a wide variety of consumer devices.
This functionality allows images taken with the camera to be displayed on a viewer, transferred to a PC and stored on large memory storage media, all with a single chip.
By using a programmable DSP, these devices can be quickly adapted for additional new applications simply by downloading new software.
The DM270 has been developed with a focus on digital cameras as its target application, as evident by the design-in commitments from multiple leading camera customers.
However, the DM270 is well suited to power a variety of multimedia applications including portable multimedia jukeboxes, camera phones, DVD players, televisions and digital video recorders.
The DM270 is scheduled for sampling in the first quarter of 2003, with volume production expected in July 2003.
Costs are expected to be less than $15 each in quantities of 25,000 for production silicon.
Evaluation modules (EVMs) with a charge coupled device (CCD) imager board plus Code Composer Studio are also currently available to help OEMs begin development on new systems.
Costs include $2900 for the EVM, from $1000 to $1500 for the CCD imager board, and $4500 for OMAP Code Composer Studio.
