Texas Instruments (TI) today announced the launch of four new DSP-based digital media processors that further expand the product portfolio of digital video solutions. The sample is available immediately, and the new product is priced at just $9.95. The family's DaVinciTM-based processors are ideal for specific applications such as automotive vision, video security surveillance systems and video telephony.Gerard Andrews, TI's marketing manager for DSP, pointed out: "Many digital video applications will change the way cars and other everyday activities experience, including vision-based assisted driving and active safety systems, residential IP webcams, and consumer video phones. TI has launched products for these applications to ensure that customers can adapt to the rapidly growing market demand in time to achieve digital video at a low price point in new applications."
The four new TMS320DM643x processors are the first DSP-only products in DaVinci technology to deliver higher processing performance at lower price points. Under the influence of Moore's Law, combined with the enhanced DSP core and the latest Video Processing Subsystem (VPSS), the DM643x processor can improve video performance, achieve up to H.264 video encoding with D1 resolution, and with previous generation DSP digital media. Compared to the processor, the cost is reduced by 50%. All four processors feature the new TMS320C64x+TM core and operate from 300 to 600 MHz.
With an integrated preview engine, image scaling tool, and on-screen display accelerator, VPSS achieves a performance boost of up to 40%, leaving room for adding more functionality to the DSP. In addition, integrating up to four DACs reduces system cost by as much as $4. For more applications, the TMS320DM6437, TMS320DM6435, TMS320DM6433, and TMS320DM6431 also reserve enough space for network functions, user interfaces, and other tasks required to run a complete DSP system.
Three new processors, the DM6431, DM6435 and DM6437, offer dedicated features that are ideal for automotive video applications such as lane departure warning and collision avoidance systems. All of the above processors support a Control Area Network (CAN) bus interface, which allows communication between multiple microcontrollers and has become the standard in the automotive industry. In addition, these devices are also compliant with the AEC-Q1000 automotive quality standards, which means they have passed a series of specific high-intensity tests required by the certification.
Roger Appelo, global strategy manager for Active Security Products at Sensata Technologies, points out: "TI offers processors for video applications and integrates automotive-specific interfaces to help drive the automotive vision market. The DM643x devices not only integrate the CAN bus. The interface is also AEC-Q100 certified, which will allow us to provide DSP performance for the vision sensor's vision sensor."
The above four processors offer 32 KB L1P cache/SRAM; 32 KB or 80 KB L1D; 64 or 128 KB L2 cache SRAM memory; and asynchronous 8-bit wide EMIF. The DM643x device family includes 32-bit DDR2 SDRAM (266 MHz) memory controllers, which are critical for digital video applications that require higher memory bandwidth. In addition, the other peripherals offered by all four processors include 10/100 Ethernet Media Access Controller (MAC), two UARTs, I2C, SPI, GPIO, McASP and three PWMs. The DM6433 and DM6437 also integrate 32-bit PCI (33 MHz). These processors are pin compatible in both 16 × 16 mm2 and 23 × 23 mm2 packages.
The four DM643x processors leverage the DaVinci software and development infrastructure, allowing designers to focus on application functional design. Developers can also implement video, video, voice, and audio technologies by easily calling the DaVinci application programming interface (API) to manage the implementation of a dedicated codec engine and match screen resolution. For example, developers can easily implement function calls without having to consider the implementation details of the actual codec. The DM643x devices support traditional DSP programming methods, and designers can do this using TI's industry-best eXpressDSPTM software and development tools, including the Code Composer StudioTM integrated development environment.
Samples of these devices are available now, with volume production scheduled for the second quarter of 2007, with unit prices ranging from $9.95 to $22.95 per unit. The complete and reliable digital video development platform leverages the DaVinci technology community provided by third-party networks, including codec engines, eXpressDSPTM data visualization technology, and DM643x devices (scheduled for release in the second quarter of 2007) Digital media software.
