Texas Instruments TMS320DM355 DaVinci Processor

The TMX320DM355ZCE216 from Texas Instruments Incorporated (TI) (NYSE: TXN) is a new embedded DaVinci(TM) processor with ARM host control and complete development tools. At a price of less than $10, the new TMS320DM355 digital media processor provides HD video performance and double the battery life of today’s HD products. Tuned for applications such as digital cameras, IP video cameras, digital photo frames and video baby monitors, the DM355 processor consists of an integrated video processing subsystem, an MPEG-4-JPEG co-processor (MJCP), an ARM926EJ-S core and peripherals. The corresponding development tool, the DM355 Digital Video Evaluation Module (DVEVM), will help developers quickly and easily create low-cost portable, digital video devices with HD video capability.

The processor is available in clock speeds of 216 MHz or 270 MHz, which allows for a scalable line of products. Likewise, developers can re-use intellectual property from the robust DaVinci technology portfolio or leverage IP from the vast open-source resources for ARM-based processing to speed them throughout the development process. Other applications that will benefit from implementing the DM355 include commercial products, such as medical imaging, ultra low-cost digital video recorders and portable test equipment.

Optimized for HD video, the DM355 processor achieves its impressive performance by integrating a video/imaging coprocessor to achieve a sub-$10 price and enable ultra-low power consumption. The MJCP provides HD MPEG-4 SP encode or decode at 720p and 30 frames per second and JPEG encode or decode at 50 MegaPixels per second. The video processing subsystem, which is featured on all DaVinci devices, integrates a preview engine, histogram, resizer and on-screen display all in hardware. The MJCP provides the equivalent of 400 MHz of digital signal processing (DSP) to achieve HD video, while the video processing subsystem tasks equate to approximately 240 MHz of performance on a DSP. Combined, the MJCP and video processing subsystem provide the equivalent of up to 640 MHz of DSP processing performance, and up to 270MHz of ARM processing capabilities are still available for product differentiation. The DM355 also includes a carefully selected suite of peripherals, such as high speed USB 2.0 On-The-Go. The integrated 10-bit D-A converter and video encoder also saves developers up to $2 in the bill of materials, as well as the associated manufacturing and design costs compared to the use of discrete parts. Priced at less than $10, the DM355 processor is an even greater value because it includes the production-qualified HD MPEG-4 and JPEG codecs without the need to pay licensing fees or royalties to TI.

Systems built with the DM355 will experience battery life that is up to twice the life of currently available portable HD systems. Depending on the application, the DM355 consumes approximately 400mW during HD MPEG-4 encoding and only 1mW of stand-by power. As an example, this means that consumers using DM355-based digital cameras in video mode can expect to record 80 minutes of HD video while using just two AA batteries.

The DaVinci TMX320DM355ZCE216 processor is now sampling from TI and TI authorized distributors. The 216MHz version will be priced in volume production at $9.75 in 50Ku and the 270MHz version will be $11.49 in 50ku. The highly integrated device is packaged in a 13 x 13 mm, 329 pin, 0.65mm pitch BGA package. The TMDXEVM355 Digital Video Evaluation Module is now available for $495.
