Why DaVinci digital video processors?

Optimized for digital video systems, DaVinci digital video processor solu-

tions are tailored for digital audio, video, imaging, and vision applications.

The DaVinci platform includes a general-purpose processor, video acceler-

ators, an optional DSP, and related peripherals. With over 200+ devices,

offerings include a wide range of performance, power and price points.

Optimized for video encode and decode applications, the scalable DaVinci

platform of solutions also includes free multimedia codecs and easy-to-use

(SoC) architecture is suited for products requiring intensive signal process-

ing, comprehensive system control, a responsive graphical user interface

and the ability to run applications under advanced operating systems.

(

• Robust offerings that include multiple operating frequencies, 3D graphics

acceleration, multiple packaging options and temperature ranges

• Integrated high-bandwidth connectivity peripherals including: HD video

coprocessor, 3D graphics core, CAN, DDR2/DDR3 interfaces, Gigabit

Ethernet, PCI Express, SATA 2.0 and USB 2.0

• Demo in 10 minutes and develop in less than an hour with robust

Linux™ and Android™ software development kits

• Accelerate both software and hardware development with low-cost

development tools and free software base ports

Everything you need to get to market faster

TI has launched free software development tools to enable developers to

easily leverage the real-time, intensive signal processing power of the

C6x DSP for DaVinci’s digital video processors.

•

GStreamer DMAI Plug-In – Pipeline-based multimedia framework that

allows you to create a variety of media-handling software components,

including simple audio playback, audio and video playback, recording,

streaming, and editing

•

C6EZAccel – Bundles TI’s extensive set of C6x DSP kernels and source

libraries for many common processing functions

•

C6EZRun – User uses ARM APIs to access the DSP and partitions code

between ARM and DSP for user without writing any DSP code

Key applications

Software/hardware tools to simplify development

TI provides customers with standard software methods to accelerate

applications on the DSP and hardware coprocessors. DSP/BIOS™ Link

provides the foundation for the ARM to load, start and communicate with

the DSP, saving precious ARM MIPS. The Codec Engine algorithm frame-

work provides the ARM developer an additional level of abstraction, which

automates the instantiation and invocation of eXpressDSP™-compliant

codecs and algorithms. Software Development Kits (SDKs), provided with

each EVM, are available for download for free and provide key software

components and documentation. Hardware development kits including

EVMs, starter kits and experimenter boards are available for purchase.
