3/4/2003 - Enabling the consumer to create higher quality digital video and imaging content, Texas Instruments Incorporated (NYSE: TXN) (TI) announced its newest DSP-based digital media processor, plus a full suite of support software and development tools. Targeting digital still cameras in the 3-5 megapixel range, digital video cameras and portable multimedia products, this offering provides fast shot-to-shot image capture performance, the latest compression video and imaging algorithms and single-channel MPEG-4 encoding at 30 frames-per-second (fps) for VGA resolution video--without compromising product size, speed or ease-of-use.
As digital media products providing higher resolution images become more popular, programmable chips that process greater volumes of data at higher speeds are in demand. The TMS320DM270 (DM270) is a highly efficient digital media solution that integrates the low-power TMS320C54xTM DSP, the ARM7TDMI® RISC processor, plus video and imaging coprocessors to improve performance, providing OEMs with a flexible platform suitable for a variety of portable imaging and multimedia products. This approach enables OEMs to expand the breadth of their product portfolio while reducing development costs.
Tools, Software and Support
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 system-on-a-chip (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 eXpressDSPTM Real-Time Software Technology, which includes the Code Composer StudioTM integrated development environment (IDE) and the DSP/BIOSTM 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.
TI also offers high performance analog products that enhance its portable digital media platforms, including ultra-low-power microcontrollers, analog front ends, audio codecs, power management devices, direct current to direct current (DC/DC) controllers, low dropout regulators, data converters, and 1394 controllers.
Prices and Availability
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 $2,900 for the EVM, from $1,000 - $1,500 for the CCD imager board, and $4500 for OMAPTM Code Composer Studio.
