MUNICH, Nov. 20 /Xinhua-PRNewswire/ -- Continuing to expand the
availability of digital video, Texas Instruments Incorporated (TI) (NYSE:
TXN) is now sampling four new digital signal processor (DSP)-based digital
media processors priced as low as $9.95. These DaVinci(TM) processors are
tuned for specific markets, including automotive vision, video security and
video telephony. For more information see http://www.ti.com/dm643xpr .

“Vision-based driver assistance and active safety systems, residential
IP netcams and consumer-class videophones are just a few of the digital video
applications that will change how we experience our car and beyond,” said
Gerard Andrews, DSP marketing manager, TI. “We have created these parts to
ensure our customers are able to capture these exploding markets, while new
low price points will allow the implementation of digital video in a
completely new realm of applications.”
Improved Video Performance, 50 Percent Cost Reduction
The four new TMS320DM643x processors, the first DSP-only devices for
DaVinci technology, are providing greater processing power at a lower price
point than ever before. Moore’s Law combined with improvements to the DSP
core and the addition of a video processing subsystem (VPSS), allow the
DM643x processors to offer improved video performance of up to H.264 video
encode at D1 resolution and a 50 percent cost reduction over TI’s previous
DSP digital media processors. All four processors feature the new TMS320C64x+
(TM) core and operate between 300 and 600 MHz.
The VPSS provides up to a 40 percent performance lift by integrating a
preview engine, resizer and on-screen display accelerator, which leaves
headroom on the DSP for additional functionality. Further, the integration
of up to four DACs reduce the system bill of materials by up to $4. For many
applications, the TMS320DM6437, TMS320DM6435, TMS320DM6433 and TMS320DM6431
will have enough headroom for networking, user interface and other tasks
required to run the complete system on the DSP.
Right Performance, Peripheral and Cost Options for Target Video Markets
Three of the new processors (DM6431, DM6435 and DM6437) offer special
features that make them suitable for automotive vision applications, such as
lane departure warning and collision avoidance. They support the CAN
(controller area network) bus interface, a network that enables multiple
microcontrollers to communicate with each other and has become a standard in
the automotive industry. These devices will meet the AEC-Q100 automotive
quality standard, which means they will pass a series of specific stress
tests required for automotive qualification.
“By offering processors specifically suited for video applications and
with automotive-specific interfaces incorporated, TI will help drive the
growth of the automotive vision market. The DM643x devices incorporate
features, such as CAN bus interface and AEC-Q100 qualification, which will
allow us to incorporate DSP performance into our vision sensors for driver
assistance systems,” said Roger Appelo, global strategy manager, Active
Safety, Sensata Technologies.
The four processors provide 32 KB L1P cache/SRAM, and either 32 KB or 80
KB L1D and 64 or 128 KB L2 Cache SRAM memory and an asynchronous 8-Bit wide
EMIF. The DM643x devices include a 32-Bit DDR2 SDRAM (266 MHz) memory
controller, which is important for digital video applications which require
higher memory bandwidth. Other peripherals offered by all four processors
include a 10/100 Ethernet media access controller (MAC), two UARTs, I2C, SPI,
GPIO, McASP and three PWMs. The DM6433 and DM6437 also incorporate 32-bit PCI
(33 MHz). The processors are available in 16 mm and 23 mm square packages and
are pin compatible.
The four DM643x processors take full advantage of the DaVinci software
and development infrastructure by allowing designers to focus on the
application functionality. Developers are able to implement video, imaging,
speech and audio technology through simple calls to the DaVinci application
programming interface (API) that manages the implementation of specific codec
engines and matching screen resolution. For example, the developer can use a
simple function call without being concerned with the details of the actual
codec implementation. The DM643x devices can also be programmed using
conventional DSP programming methods with TI’s best-in-class eXpressDSP(TM)
software and development tools, including Code Composer Studio(TM) Integrated
Development Environment.
Samples Available to Begin Development Today
Samples are available today and devices will be in volume production in
2Q 2007, priced from $9.95 to $22.95 in 10,000 units. A complete, robust
digital video development platform that leverages the entire DaVinci
technology ecosystem, including the codec engine, eXpressDSP(TM) Data
Visualization Technology and digital media software for the DM643x devices
will be released in 2Q 2007. The DM643x H.264 encode demonstration is in the
TI booth at Electronica (Booth #125, Hall A4) in Munich and at Embedded
Technology 2006 (C-29) in Tokyo.
