The Linux Digital Video Software Development Kits (DVSDKs) enable DaVinci system integrators to quickly develop Linux-based multimedia applications that can be easily ported across different devices in the DaVinci family. Each DVSDK combines a pre-tested set of operating system, application framework, and codec libraries with example programs that demonstrate decode and encode of audio and video data streamed in real-time to and from peripheral devices. For DaVinci devices that feature DSP cores, the DVSDKs provide a complete framework for developers to easily leverage DSP-accelerated codecs without having to program the DSP. DVSDKs are free and do not require any run-time royalties.

Features

• MontaVista Linux (MVL) Professional Edition 5.0: This is a demonstration copy of MVL Pro 5.00 with complete host (for example, build tools) and target file systems. MontaVista Pro 5.0 is based on the Linux 2.6.18 kernel. The demonstration copy may be shipped in production systems, but developers will typically need to optimize the file system contents for their application. Developers can optionally purchase the MontaVista DevRocket IDE, access to updates and support documentation via the Monta Vista Zone, and the Monta Vista library optimization tool that simplifies customization of Linux configurations.
• Linux Support Package (LSP): The LSP contains the drivers for the on-chip peripherals for a DaVinci device and EVM peripherals. Developers who require further technical details on the Linux drivers for a device should go to the DVSDK download page and reference the Driver Data Sheet for the specific LSP.
• Bootloading (u-boot) software to boot Linux from a variety of peripherals.
• The Codec Engine Multimedia stack: The Codec Engine algorithm execution framework provides a consistent set of multimedia codec APIs, known as xDM, regardless of whether the codec is being executed on the ARM, DSP, or dedicated accelerator. Developers can then build higher-level multimedia framework functions, such as AV Sync or stream parsing, on top of Codec Engine. For developers whose expertise is in Linux application development, Codec Engine enables developers to remotely instantiate and execute codecs and algorithms on the DSP without needing to write any DSP code.
• DaVinci Multimedia Interface (DMAI): DMAI allows development of highly portable multimedia applications that can move easily from one device or operating system to another.
• Multimedia codecs: The DVSDK provides codec libraries and associated AV clips that enable developers to immediately develop and evaluate real-world applications. These codecs may be in dedicated hardware (DM355S) or DSP-accelerated. The following all available for download now, along with the DVSDK. They are production quality codecs, with production software licensing agreements.
  - DM644x Codec Server: H.264 Enc/Dec, MPEG-4 Enc/Dec, MPEG-2 Dec, AAC HE Dec, G.711 Enc/Dec, plus TI Codec Engine, etc.
  - DM6467 Codec Server: H.264 HP Dec, H.264 BP Enc, MPEG-2 MP Dec, AAC LC Enc/Dec, G.711 Enc/Dec, plus TI Codec Engine, etc.
  - DM365 Codecs: H.264 Enc/Dec, MPEG-4 Enc/Dec, JPEG Enc/Dec
  - DM355 Codecs: MPEG-4 Enc/Dec, JPEG Enc/Dec
• Demonstration programs: The demo programs show decoding and encoding operations to illustrate how frameworks, codecs, video and audio subsystem drivers are integrated to implement complete applications.

• DSP/BIOS operating system: DSP/BIOS is a preemptive, multitasking, real-time kernel that simplifies creation of multithreaded DSP application.
• DSP/BIOS Link: DSP/BIOS Link is ARM-DSP communication software that enables the ARM to bootload the DSP and for the two processors to pass messages and data buffers via shared memory.
• xDAIS Developer’s Kit: xDAIS and xDM are algorithm integration standards that make it easier to implement applications that must use multiple different codecs. Algorithms adhering to the xDAIS standard access shared resources such as internal memory and DMA through the framework, enabling the framework to prevent one codec overwriting the resources used by another. xDM provides standard APIs for different classes of codecs that enable an application to invoke, for example, MPEG4 or H.264 decoders from different vendors without having to change any code.
• Framework Components: Framework Components are modules that simplify implementation of frameworks that wish to use xDAIS-compliant algorithms.
• EDMA3 Driver: This driver provides APIs to utilize DaVinci’s powerful DMA capabilities. The EDMA3 driver includes resource management support to enable developers to safely share DMA resources between different parts of the application.
