Power chip makes the most of a single cell
A buck-boost power management IC helps extend battery life in smart phones, digital still cameras and other single-cell lithium-ion powered multimedia devices.
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 DM355 digital video evaluation module (DVEVM), will help developers quickly and easily create low-cost portable, digital video devices with HD video capability.
"With this DaVinci offering, developers can add HD video functionality at a low price point and execute a quick launch of their product into the fast-growing HD market", said John Dixon, DaVinci Marketing Manager, Texas Instruments.

A new analogue-to-digital video decoder combines four independent video decoders into a single chip.
"The DM355 is tuned to provide the critical balance of price, performance and power for these aggressive markets in an effort to ensure our customers' success".
The processor is available in clock speeds of 216 or 270MHz, which allows for a scalable line of products.
Developers can re-use intellectual property from the DaVinci technology portfolio or leverage IP from the open-source resources for ARM-based processing to speed them throughout the development process.
Other applications that will benefit from implementing the DM355 include medical imaging, ultra low-cost digital video recorders and portable test equipment.
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 400MHz of digital signal processing (DSP) to achieve HD video, while the video processing subsystem tasks equate to approximately 240MHz of performance on a DSP.
Combined, the MJCP and video processing subsystem provide the equivalent of up to 640MHz of DSP processing performance, and up to 270MHz of ARM processing capabilities are still available for product differentiation.
The DM355 also includes a suite of peripherals, such as high speed USB 2.0 On-The-Go.
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.
This means that consumers using DM355-based digital cameras in video mode can expect to record 80 minutes of HD video while using two AA batteries.
The DM355 processor and DVEVM take advantage of all the tools and support included in the DaVinci technology portfolio to help product developers save months of time.
The application programming interfaces (APIs) common across DaVinci offerings also means that developers familiar with DaVinci technology or ARM development can quickly develop their products with virtually no learning curve.
When coupled with the DVEVM, developers are able to get started immediately with product development.
